#### Summary of Changes
This PR enables RocksDB read side performance metrics to report to blockstore_rocksdb_read_perf.
The sampling rate is controlled by an env arg `SOLANA_METRICS_ROCKSDB_PERF_SAMPLES_IN_1K`,
specifies the number of perf samples for every 1000 operations. The default value is set to 10, meaning
we will report 10 out of 1000 (or 1/100) reads.
The metrics are based on the RocksDB [PerfContext](https://github.com/facebook/rocksdb/blob/main/include/rocksdb/perf_context.h).
It includes many useful metrics including block read time, cache hit rate, and time spent on decompressing the block.

This PR renames BlockstoreAdvancedOptions to LedgerColumnOptions, as we will
pass-down this struct to LedgerColumn to allow it to perform metric reporting.
#### Summary of Changes
This PR further enables group by operation on storage type in blockstore_rocksdb_cfs metrics.
Such group-by allows us to further compare the performance metrics between rocks-level and
rocks-fifo.
To make things extensible, this PR introduces BlockstoreAdvancedOptions and move shred_storage_type.
All fields in BlockstoreAdvancedOptions will support group-by operation in blockstore_rocksdb_cfs.
Dependency: #23580
This PR enables blockstore to periodically report RocksDB column family properties.
The reported properties are under blockstore_rocksdb_cfs, and the properties also
support group by operation on cf_name.
#### Summary of Changes
This PR adds two hidden arguments to the validator that allow users to use RocksDB's FIFO compaction for storing shreds.
--shred-storage <SHRED_STORAGE>
EXPERIMENTAL: Controls how RocksDB compacts shreds. *WARNING*: You will lose your ledger data
when you switch between options. Possible values are: 'level': stores shreds using RocksDB's default (level)
compaction. 'fifo': stores shreds under RocksDB's FIFO compaction. This option is more efficient on
disk-write-bytes of the ledger store. [default: level] [possible values: level, fifo]
--shred-storage-size <SHRED_STORAGE_SIZE_BYTES>
The shred storage size in bytes. The suggested value is 50% of your ledger storage size in bytes. [default:

The indices for erasure coding shreds are tied to data shreds:
https://github.com/solana-labs/solana/blob/90f41fd9b/ledger/src/shred.rs#L921
However with the upcoming changes to erasure schema, there will be more
erasure coding shreds than data shreds and we can no longer infer coding
shreds indices from data shreds.
The commit adds constructs to track coding shreds indices explicitly.
next-shred-index is already readily available from returned data shreds.
The commit simplifies the api for upcoming changes to erasure coding
schema which will require explicit tracking of indices for coding shreds
as well as data shreds.

SlotMeta.last_index may be unknown and current code is using u64::MAX to
indicate that:
https://github.com/solana-labs/solana/blob/6c108c8fc/ledger/src/blockstore_meta.rs#L169-L174
This lacks type-safety and can introduce bugs if not always checked for
Several instances of slot_meta.last_index + 1 are also subject to
overflow.
This commit updates the type to Option<u64>. Backward compatibility is
maintained by customizing serde serialize/deserialize implementations.
https://github.com/solana-labs/solana/pull/17004
removed position field from coding-shred-header because as it stands the
field is redundant and unused.
However, with the upcoming changes to erasure coding schema this field
will no longer be redundant and needs to be populated.
* Moves create_message(), native_invoke() and process_cross_program_instruction()

Turbine randomly shuffles cluster nodes on a broadcast tree for each
shred. This requires knowing the stakes and nodes' contact-infos (from
gossip).
However gossip is subject to partitioning and propogation delays.
Additionally unstaked nodes may join and leave the cluster at any
moment, changing the cluster view from one node to another.
This commit:
* Always arranges the unstaked nodes at the bottom of turbine broadcast
tree.
* Staked nodes are always included regardless of if their contact-info
is available in gossip or not.
* Uses the unbiased WeightedShuffle construct for shuffling nodes.
* add filler accounts to bloat validator and predict failure
* assert no accounts match filler
* cleanup magic numbers
* panic if can't load from snapshot with filler accounts specified
* some renames
* renames
* into_par_iter
* clean filler accts, too
Support using connection pooling and use multiple threads to do Postgres db operations. The performance is improved from 1500 RPS to 40,000 RPS measured during validator start.
Support multiple plugins at the same time.
Now that CRDS supports incremental snapshot hashes,
SnapshotPackagerService needs to push 'em!
This commit does two main things:
1. SnapshotPackagerService now knows about incremental snapshot hashes,
and will push SnapshotPackage::IncrementalSnapshot hashes to CRDS.
2. At startup, when loading from a full + incremental snapshot, the
hashes need to be passed all the way to SnapshotPackagerService so it
can push these starting hashes to CRDS. Those values have been piped
through.

Summary of Changes
Create a plugin mechanism in the accounts update path so that accounts data can be streamed out to external data stores (be it Kafka or Postgres). The plugin mechanism allows
Data stores of connection strings/credentials to be configured,
Accounts with patterns to be streamed
PostgreSQL implementation of the streaming for different destination stores to be plugged in.
The code comprises 4 major parts:
accountsdb-plugin-intf: defines the plugin interface which concrete plugin should implement.
accountsdb-plugin-manager: manages the load/unload of plugins and provide interfaces which the validator can notify of accounts update to plugins.
accountsdb-plugin-postgres: the concrete plugin implementation for PostgreSQL
The validator integrations: updated streamed right after snapshot restore and after account update from transaction processing or other real updates.
The plugin is optionally loaded on demand by new validator CLI argument -- there is no impact if the plugin is not loaded.

This is the 2nd installment for the AccountsDb replication.
Summary of Changes
The basic google protocol buffer protocol for replicating updated slots and accounts. tonic/tokio is used for transporting the messages.
The basic framework of the client and server for replicating slots and accounts -- the persisting of accounts in the replica-side will be done at the next PR -- right now -- the accounts are streamed to the replica-node and dumped. Replication for information about Bank is also not done in this PR -- to be addressed in the next PR to limit the change size.
Functionality used by both the client and server side are encapsulated in the replica-lib crate.
There is no impact to the existing validator by default.
Tests:
Observe the confirmed slots replicated to the replica-node.
Observe the accounts for the confirmed slot are received at the replica-node side.
AccountsBackgroundService now knows about incremental snapshots. It is
now also in charge of deciding if an AccountsPackage is destined to be a
SnapshotPackage or not (or just used by AccountsHashVerifier).
!!! New behavior changes !!!
Taking snapshots (both bank and archive) **MUST** succeed.
This is required because of how the last full snapshot slot is
calculated, which is used by AccountsBackgroundService when calling
`clean_accounts()`.
File system calls are now unwrapped and will result in a crash. As Trent told me:
>Well I think if a snapshot fails due to some IO error, it's very likely that the operator is going to have to intervene before it works. We should exit error in this case, otherwise the validator might happily spin for several more hours, never successfully writing a complete snapshot, before something else brings it down. This would leave the validator's last local snapshot many more slots behind than it would be had we exited outright and potentially force the operator to abandon ledger continuity in favor of a quick catchup
Other errors will set the `exit` flag to `true`, and the node will gracefully shutdown.
Fixes#19167Fixes#19168
#### Problem
Snapshot names are overloaded, and there are multiple terms that mean the same thing. This is confusing. Here's a list of ones in the codebase that I've found:
```
- snapshot_dir
- snapshots_dir
- snapshot_path
- snapshot_output_dir
- snapshot_package_output_path
- snapshot_archives_dir
```
#### Summary of Changes
For all the ones that are about the directory where snapshot archives are stored, ensure they are `snapshot_archives_dir`. For the ones about the (bank) snapshots directory, set to `bank_snapshots_dir`.

Shreds recovered from erasure codes have not been received from turbine
and have not been retransmitted to other nodes downstream. This results
in more repairs across the cluster which is slower.
This commit channels through recovered shreds to retransmit stage in
order to further broadcast the shreds to downstream nodes in the tree.
Working towards sending shreds (instead of packets) to retransmit stage
so that shreds recovered from erasure codes are as well retransmitted.
Following commit will add these metrics back to window-service, earlier
in the pipeline.
Cross cluster gossip contamination is causing cluster-slots hash map to
contain a lot of bogus values and consume too much memory:
https://github.com/solana-labs/solana/issues/17789
If a node is using the same identity key across clusters, then these
erroneous values might not be filtered out by shred-versions check,
because one of the variants of the contact-info will have matching
shred-version:
https://github.com/solana-labs/solana/issues/17789#issuecomment-896304969
The cluster-slots hash-map is bounded and trimmed at the lower end by
the current root. This commit also discards slots epochs ahead of the
root.
Renaming these types to better communicate their usages, which will
further diverge as incremental snapshot support is added.
With the new names, AccountsPacakge now refers to the type between
AccountsBackgroundProcess and AccountsHashVerifier, and SnapshotPackage
refers to the type between AccountsHashVerifier and
SnapshotPackagerService.
* added realtime cost checking logic to reject block that would exceed max limit:
- defines max limits at block_cost_limits.rs
- right after each bath's execution, accumulate its cost and check again
limit, return error if limit is exceeded
* update abi that changed due to adding additional TransactionError
* To avoid counting stats mltiple times, only accumulate execute-timing when a bank is completed
* gate it by a feature
* move cost const def into block_cost_limits.rs
* redefine the cost for signature and account access, removed signer part as it is not well defined for now
* check if per_program_timings of execute_timings before sending
AccountsHashVerifier will need access to both the full and incremental
snapshot archive interval slots config values, which is in the
SnapshotConfig.
Also, cleanup some `Option<>` params and their references.
While reviewing PR #18565, as issue was brought up to refactor some code
around verifying the bank after rebuilding from snapshots. A new
top-level function has been added to get the latest snapshot archives
and load the bank then verify. Additionally, new tests have been
written and existing tests have been updated to use this new function.
Fixes#18973
While resolving the issue, it became clear there was some additional
low-hanging fruit this change enabled. Specifically, the functions
`bank_to_xxx_snapshot_archive()` now return their respective
`SnapshotArchiveInfo`. And on the flip side,
`bank_from_snapshot_archives()` now takes `SnapshotArchiveInfo`s instead
of separate paths and archive formats. This bundling simplifies bank
rebuilding.
bank.get_leader_schedule_epoch(shred_slot)
is one epoch after epoch_schedule.get_epoch(shred_slot).
At epoch boundaries, shred is already one epoch after the root-slot. So
we need epoch-stakes 2 epochs ahead of the root. But the root bank only
has epoch-stakes for one epoch ahead, and as a result looking up epoch
staked-nodes from the root-bank fails.
To be backward compatible with the current master code, this commit
implements a fallback on working-bank if epoch staked-nodes obtained
from the root-bank is none.
If two threads simultaneously call into ClusterNodesCache::get for the
same epoch, and the cache entry is outdated, then both threads recompute
cluster-nodes for the epoch and redundantly overwrite each other.
This commit wraps ClusterNodesCache entries in Arc<Mutex<...>>, so that
when needed only one thread does the computations to update the entry.
* Current caching mechanism does not update cluster-nodes when the epoch
(and so epoch staked nodes) changes:
https://github.com/solana-labs/solana/blob/19bd30262/core/src/broadcast_stage/standard_broadcast_run.rs#L332-L344
* Additionally, the cache update has a concurrency bug in which the
thread which does compare_and_swap may be blocked when it tries to
obtain the write-lock on cache, while other threads will keep running
ahead with the outdated cache (since the atomic timestamp is already
updated).
In the new ClusterNodesCache, entries are keyed by epoch, and so if
epoch changes cluster-nodes will be recalculated. The time-to-live
eviction policy is also encapsulated and rigidly enforced.
The new cluster-nodes cache will:
* ensure cluster-nodes are recalculated if the epoch (and so the epoch
staked nodes) changes.
* encapsulate time-to-live eviction policy.
Cluster nodes are cached keyed by the respective epoch from which stakes
are obtained, and so if epoch changes cluster-nodes will be recomputed.
A time-to-live eviction policy is enforced to refresh entries in case
gossip contact-infos are updated.
This commit also renames `snapshot_interval_slots` to
`full_snapshot_archive_interval_slots`, updates the comments on the
fields, and make appropriate updates where SnapshotConfig is used.
* wip - cost_update_services to log both us and cu for each instruction to determine possible ratio
* replace microsecond with compute_unit as cost unit
This commit adds high-level functions for creating and loading-from
incremental snapshots, plus all low-level functions required to perform
those tasks. This commit **does not** add taking incremental snapshots
as part of a running validator, nor starting up a node with an
incremental snapshot; just laying ground work.
Additionally, `snapshot_utils` and `serde_snapshot` have been
refactored to use a common code paths for the different snapshots.
Also of note, some renaming has happened:
1. Snapshots are now either `full_` or `incremental_` throughout the
codebase. If not specified, the code applies to both.
2. Bank snapshots now are called "bank snapshots"
(before they were called "slot snapshots", "bank snapshots", or
just "snapshots"). The one exception is within `Bank`, where they
are still just "snapshots", because they are already "bank
snapshots".
3. Snapshot archives now have `_archive` in the code. This
should clear up an ambiguity between bank snapshots and snapshot
archives.
This commit adds CrdsEntry trait which allows generic lookups into crds
table. For example to get ContactInfo or LowestSlot associated with a
Pubkey, the lookup code would be respectively:
crds.get::<&ContactInfo>(pubkey)
crds.get::<&LowestSlot>(pubkey)
* Move transaction sanitization earlier in the pipeline
* Renamed HashedTransaction to SanitizedTransaction
* Implement deref for sanitized transaction
* bring back process_transactions test method
* Use sanitized transactions for cost model calculation
push_lowest_slot cannot sign the new crds-value unless the id (pubkey)
argument passed-in is the same pubkey as in ClusterInfo::keypair(), in
which case the id argument is redundant:
https://github.com/solana-labs/solana/blob/bb41cf346/gossip/src/cluster_info.rs#L824-L845
Additionally, the lookup is done with self.id(), but insert is done with
the id argument, which is logically a bug.
1. check transaction has valid program_id before using it to avoid possible panic;
2. change calculate_cost function signature to return Result;
3. add CostModelError enum, update return type from Result<_, str> to Result<_, CostModelError>
* update ledger tool to restore cost model from blockstore when compute-slot-cost
* Move initialize_cost_table into cost_model, so the function can be tested and shared between validator and ledger-tool
* refactor and simplify a test
The repair-peers cache is reset each time repair service loop runs,
and so computed repeatedly for the same slots:
https://github.com/solana-labs/solana/blob/d2b07dca9/core/src/repair_service.rs#L275
This commit uses an LRU cache to persists repair-peers for each slot.
In addition to LRU eviction rules, in order to avoid re-using outdated
data, each entry also has 10 seconds TTL.
Broadcast stage and retransmit stage should arrange nodes on turbine
broadcast tree in exactly same order. Additionally any changes to this
ordering (e.g. updating how unstaked nodes are handled) requires feature
gating to keep the cluster in sync.
Current implementation is scattered out over several public methods and
exposes too much of implementation details (e.g. usize indices into
peers vector) which makes code changes and checking for feature
activations more difficult.
This commit encapsulates turbine peer computations into a new struct,
and only exposes two public methods, get_broadcast_peer and
get_retransmit_peers, for call-sites.
* Add `ProgramCosts` Column Family to blockstore, implement LedgerColumn; add `delete_cf` to Rocks
* Add ProgramCosts to compaction excluding list alone side with TransactionStatusIndex in one place: `excludes_from_compaction()`
* Write cost table to blockstore after `replay_stage` replayed active banks; add stats to measure persist time
* Deletes program from `ProgramCosts` in blockstore when they are removed from cost_table in memory
* Only try to persist to blockstore when cost_table is changed.
* Restore cost table during validator startup
* Offload `cost_model` related operations from replay main thread to dedicated service thread, add channel to send execute_timings between these threads;
* Move `cost_update_service` to its own module; replay_stage is now decoupled from cost_model.
* Add stats and counter around cost model ops, mainly:
- calculate transaction cost
- check transaction can fit in a block
- update block cost tracker after transactions are added to block
- replay_stage to update/insert execution cost to table
* Change mutex on cost_tracker to RwLock
* removed cloning cost_tracker for local use, as the metrics show clone is very expensive.
* acquire and hold locks for block of TXs, instead of acquire and release per transaction;
* remove redundant would_fit check from cost_tracker update execution path
* refactor cost checking with less frequent lock acquiring
* avoid many Transaction_cost heap allocation when calculate cost, which
is in the hot path - executed per transaction.
* create hashmap with new_capacity to reduce runtime heap realloc.
* code review changes: categorize stats, replace explicit drop calls, concisely initiate to default
* address potential deadlock by acquiring locks one at time
When starting a validator, the node initially joins gossip with
shred_verison = 0, until it adopts the entrypoint's shred-version:
https://github.com/solana-labs/solana/blob/9b182f408/validator/src/main.rs#L417
Depending on the load on the entrypoint, this adopting entrypoint
shred-version through gossip sometimes becomes very slow, and causes
several problems in gossip because we have to partially support
shred_version == 0 which is a source of leaking crds values from one
cluster to another. e.g. see
https://github.com/solana-labs/solana/pull/17899
and the other linked issues there.
In order to remove shred_version == 0 from gossip, this commit adds
shred-version to ip-echo-server response. Once the entrypoints are
updated, on validator start-up, if --expected_shred_version is not
specified we will obtain shred-version from the entrypoint using
ip-echo-server.
1. Added both options for measuring space usage using total accounts usage and for individual store shrink ratio using an enum. Validator CLI options: --accounts-shrink-optimize-total-space and --accounts-shrink-ratio
2. Added code for selecting candidates based on total usage in a separate function select_candidates_by_total_usage
3. Added unit tests for the new functions added
4. The default implementations is kept at 0.8 shrink ratio with --accounts-shrink-optimize-total-space set to true
Fixes#17544
* replay stage feeds back realtime per-program execution cost to cost model;
* program cost execution table is initialized into empty table, no longer populated with hardcoded numbers;
* changed cost unit to microsecond, using value collected from mainnet;
* add ExecuteCostTable with fixed capacity for security concern, when its limit is reached, programs with old age AND less occurrence will be pushed out to make room for new programs.
* Create solana-poh crate
* Move BigTableUploadService to solana-ledger
* Add solana-rpc to workspace
* Move dependencies to solana-rpc
* Move remaining rpc modules to solana-rpc
* Single use statement solana-poh
* Single use statement solana-rpc
* Accounts dumping logic
* Add test for interaction between cache flush and remove_unrooted_slot()
* Update comments
* Rename
* renaming
* Add more comments
* Renaming
* Fixup test and bad check
* * Add following to banking_stage:
1. CostModel as immutable ref shared between threads, to provide estimated cost for transactions.
2. CostTracker which is shared between threads, tracks transaction costs for each block.
* replace hard coded program ID with id() calls
* Add Account Access Cost as part of TransactionCost. Account Access cost are weighted differently between read and write, signed and non-signed.
* Establish instruction_execution_cost_table, add function to update or insert instruction cost, unit tested. It is read-only for now; it allows Replay to insert realtime instruction execution costs to the table.
* add test for cost_tracker atomically try_add operation, serves as safety guard for future changes
* check cost against local copy of cost_tracker, return transactions that would exceed limit as unprocessed transaction to be buffered; only apply bank processed transactions cost to tracker;
* bencher to new banking_stage with max cost limit to allow cost model being hit consistently during bench iterations
* Update rocksdb to v0.16.0
* Promote the infrequent and important log to info!
* Force background compaction by ttl without manual compaction
* Fix test
* Support no compaction mode in test_ledger_cleanup_compaction
