Method Detail

getProcessedVersions

long getProcessedVersions()

 Number of user keys scanned from the storage.
 It does not include deleted version or RocksDB tombstone keys.
 For Coprocessor requests, it includes keys that has been filtered out by
 Selection.
 

uint64 processed_versions = 1;

Returns:

The processedVersions.

getProcessedVersionsSize

long getProcessedVersionsSize()

 Number of bytes of user key-value pairs scanned from the storage, i.e.
 total size of data returned from MVCC layer.
 

uint64 processed_versions_size = 8;

Returns:

The processedVersionsSize.

getTotalVersions

long getTotalVersions()

 Approximate number of MVCC keys meet during scanning. It includes
 deleted versions, but does not include RocksDB tombstone keys.
 When this field is notably larger than `processed_versions`, it means
 there are a lot of deleted MVCC keys.
 

uint64 total_versions = 2;

Returns:

The totalVersions.

getRocksdbDeleteSkippedCount

long getRocksdbDeleteSkippedCount()

 Total number of deletes and single deletes skipped over during
 iteration, i.e. how many RocksDB tombstones are skipped.
 

uint64 rocksdb_delete_skipped_count = 3;

Returns:

The rocksdbDeleteSkippedCount.

getRocksdbKeySkippedCount

long getRocksdbKeySkippedCount()

 Total number of internal keys skipped over during iteration.
 See https://github.com/facebook/rocksdb/blob/9f1c84ca471d8b1ad7be9f3eebfc2c7e07dfd7a7/include/rocksdb/perf_context.h#L84 for details.
 

uint64 rocksdb_key_skipped_count = 4;

Returns:

The rocksdbKeySkippedCount.

getRocksdbBlockCacheHitCount

long getRocksdbBlockCacheHitCount()

 Total number of RocksDB block cache hits.
 

uint64 rocksdb_block_cache_hit_count = 5;

Returns:

The rocksdbBlockCacheHitCount.

getRocksdbBlockReadCount

long getRocksdbBlockReadCount()

 Total number of block reads (with IO).
 

uint64 rocksdb_block_read_count = 6;

Returns:

The rocksdbBlockReadCount.

getRocksdbBlockReadByte

long getRocksdbBlockReadByte()

 Total number of bytes from block reads.
 

uint64 rocksdb_block_read_byte = 7;

Returns:

The rocksdbBlockReadByte.
