Crate tikv_kv[−][src]

There are multiple Engine implementations, RaftKv is used by the Server. The BTreeEngine and RocksEngine are used for testing only.

Modules

BTreeEngine	The BTreeEngine(based on `BTreeMap`) is in memory and only used in tests and benchmarks. Note: The `snapshot()` and `async_snapshot()` methods are fake, the returned snapshot is not isolated, they will be affected by the later modifies.

PerfStatisticsDelta	Store statistics we need. Data comes from RocksDB’s `PerfContext`. This statistics store delta values between two instant statistics.
