filter_crds_values checks every crds filter against every hash value:
https://github.com/solana-labs/solana/blob/ee646aa7/core/src/crds_gossip_pull.rs#L432
which can be inefficient if the filter's bit-mask only matches small
portion of the entire crds table.
This commit shards crds values into separate tables based on shard_bits
first bits of their hash prefix. Given a (mask, mask_bits) filter,
filtering crds can be done by inspecting only relevant shards.
If CrdsFilter.mask_bits <= shard_bits, then precisely only the crds
values which match (mask, mask_bits) bit pattern are traversed.
If CrdsFilter.mask_bits > shard_bits, then approximately only
1/2^shard_bits of crds values are inspected.
Benchmarking on a gce cluster of 20 nodes, I see ~10% improvement in
generate_pull_responses metric, but with larger clusters, crds table and
2^mask_bits are both larger, so the impact should be more significant.
* Add blockstore column to cache block times
* Add method to cache block time
* Add service to cache block time
* Update rpc getBlockTime to use new method, and refactor blockstore slightly
* Return block_time with confirmed block, if available
* Add measure and warning to cache-block-time
* Remove support for Budget
Also:
* Make "pay" command a deprecated alias for the "transfer" command
* chore: remove budget from web3.js
* Drop Budget depedency from core
Validators no longer ship with builtin Budget
* Add check in cluster_info_vote_listenere to see if optimstic conf was achieved
Add OptimisticConfirmationVerifier
* More fixes
* Fix merge conflicts
* Remove gossip notificatin
* Add dashboards
* Fix rebase
* Count switch votes as well toward optimistic conf
* rename
