Yueh-Hsuan Chiang 0b5ed87220 (LedgerStore) Enable performance sampling in column family get() (#23834) ... #### 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.		2022-04-01 13:13:32 -07:00
