Expand description

Represents the statistics of a region.

Fields§

§num_rows: u64

The number of rows

§memtable_size: u64

The size of memtable in bytes.

§wal_size: u64

The size of WAL in bytes.

§manifest_size: u64

The size of manifest in bytes.

§sst_size: u64

The size of SST data files in bytes.

§sst_num: u64

The num of SST files.

§index_size: u64

The size of SST index files in bytes.

§manifest: RegionManifestInfo

The details of the region.

§written_bytes: u64

The total bytes written of the region since region opened.

§data_topic_latest_entry_id: u64

The latest entry id of the region’s remote WAL since last flush. For metric engine, there’re two latest entry ids, one for data and one for metadata. TODO(weny): remove this two fields and use single instead.
