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
#### 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:
268435456000]
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.
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.
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
