* Connection pool in connection cache and handle connection errors
1. The connection not has a pool of connections per address, configurable, default 4
2. The connections per address share a lazy initialized endpoint
3. Handle connection issues better, avoid race conditions
4. Various log improvement for help debug connection issues
* client: Remove static connection cache, plumb it instead
* Add TpuClient::new_with_connection_cache to not break downstream
* Refactor get_connection and RwLock into ConnectionCache
* Fix merge conflicts from new async TpuClient
* Remove `ConnectionCache::set_use_quic`
* Move DEFAULT_TPU_USE_QUIC to client, use ConnectionCache::default()
#### Problem
Currently, the creation of ShredStorageType::RocksFifo is hard coded in validator/src/main.rs.
But this common code will also need to be used in other places like ledger-tool.
#### Summary of Changes
This PR creates a helper functionShredStorageType::rocks_fifo that takes a total shred_storage_size
and equally allocates to data-shred and coding-shred storage.
Add in some CPU utilization metrics such as: number of vCPUs, clock frequency, average load across different time intervals, and number of total threads
#### Problem
When FIFO compaction is used, the size ratio between data shred and coding
shred is set to 1:1 based on the `--rocksdb_fifo_shred_storage_size` arg.
However, BlockstoreRocksFifoOptions::default() uses a slightly optimized
5:4 ratio instead, and the default() function is only used in benchmarks.
#### Summary of Changes
This PR makes both validator argument and BlockstoreRocksFifoOptions::default()
to use 1:1 ratio between data and coding shred size.
#### Problem
blockstore_db.rs has a mutual dependency between blockstore_metrics.rs.
#### Summary of Changes
This PR removes the mutual dependency by moving the option-related stuff
out from blockstore_db.rs to its new home --- blockstore_options.rs.
By doing this, we address the mutual dependency and also make the code cleaner.
#### Problem
LedgerColumnOptions contain two fields, perf_read_counter and perf_write_counter,
that are not really options but internal counters.
#### Summary of Changes
This PR introduces BlockstoreRocksDbPerfSamplingStatus, a struct that holds internal
status for RocksDB perf sampling and moves perf_read_counter and perf_write_counter
out from LedgerColumnOptions.
#### Summary of Changes
This PR replaces the use of thread_rng in RocksDB perf metric samples by
AtomicU32 with Ordering::Relaxed to improve the performance of determining
whether to sample the current RocksDB's read/write perf metric.
#### Problem
Currently, the number of RocksDB perf samples is controlled by an env arg
which is later handled using a lazy_static variable. However, there is a known
performance overhead of using lazy_static as mentioned in
https://github.com/solana-labs/solana/pull/6472.
#### Summary of Changes
Instead, this PR uses a hidden validator argument, --rocksdb-perf-sample-interval,
for controlling how often RocksDB read/write performance sample is collected.
Introduced flag --tpu-do-batch2.
Introduced flag to control the batch size-- by default 100
The default batch timeout is 200ms -- configurable. If either it time out or the batch size is filled, a new batch is sent
The batch honor the retry rate on the transaction already sent before.
Introduced two threads in STS: one for receiving new transactions and doing batch send and one for retrying old transactions and doing batch.6.
Fixes #
* transaction-status: Add return data to meta
* Add return data to simulation results
* Use pretty-hex for printing return data
* Update arg name, make TransactionRecord struct
* Rename TransactionRecord -> ExecutionRecord
This PR adds `--rocksdb-ledger-compression` as a hidden argument to the validator
for specifying the compression algorithm for TransactionStatus. Available compression
algorithms include `lz4`, `snappy`, `zlib`. The default value is `none`.
Experimental results show that with lz4 compression, we can achieve ~37% size-reduction
on the TransactionStatus column family, or ~8% size-reduction of the ledger store size.
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]
* AcctIdx: env var "SOLANA_TEST_ACCOUNTS_INDEX_MEMORY_LIMIT_MB"
* ignore env var when starting as validator
* Update runtime/src/bucket_map_holder.rs
