* Cost Model to limit transactions which are not parallelizeable (#16694)
* * 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
* replay stage feed back program cost (#17731)
* 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.
* investigate system performance test degradation (#17919)
* 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
* Persist cost table to blockstore (#18123)
* 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.
* log warning when channel send fails (#18391)
* Aggregate cost_model into cost_tracker (#18374)
* * aggregate cost_model into cost_tracker, decouple it from banking_stage to prevent accidental deadlock. * Simplified code, removed unused functions
* review fixes
* update ledger tool to restore cost table from blockstore (#18489)
* 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
* manually fix merge conflicts
* Per-program id timings (#17554)
* more manual fixing
* solve a merge conflict
* featurize cost model
* more merge fix
* cost model uses compute_unit to replace microsecond as cost unit
(#18934)
* Reject blocks for costs above the max block cost (#18994)
* Update block max cost limit to fix performance regession (#19276)
* replace function with const var for better readability (#19285)
* Add few more metrics data points (#19624)
* periodically report sigverify_stage stats (#19674)
* manual merge
* cost model nits (#18528)
* Accumulate consumed units (#18714)
* tx wide compute budget (#18631)
* more manual merge
* ignore zerorize drop security
* - update const cost values with data collected by #19627
- update cost calculation to closely proposed fee schedule #16984
* add transaction cost histogram metrics (#20350)
* rebase to 1.7.15
* add tx count and thread id to stats (#20451)
each stat reports and resets when slot changes
* remove cost_model feature_set
* ignore vote transactions from cost model
