![]() It contains optimizations that are not in RocksDB, that are inspired by how CockroachDB uses the storage engine.It is developed by Cockroach Labs engineers.It provides atomic write batches and snapshots, which give us a subset of transactions.It is a key-value store, which makes mapping to our key-value layer simple.Pebble integrates well with CockroachDB for a number of reasons: Serves successful reads and writes from the replication layer.ĬockroachDB uses Pebble––an embedded key-value store inspired by RocksDB, and developed by Cockroach Labs––to read and write data to disk.In relationship to other layers in CockroachDB, the storage layer: More than one replica for a range will never be placed on the same store or even the same node. These stores in turn have a collection of range replicas. In addition, there is also a block cache shared amongst all of the stores in a node. One for storing temporary distributed SQL data. ![]() Internally, each store contains two instances of the storage engine: Contains optimizations that benefit CockroachDB.Is written in Go and implements a subset of RocksDB's large feature set.Pebble is inspired by RocksDB, but differs in that it: This data is stored as key-value pairs on disk using the storage engine, which is treated primarily as a black-box API.ĬockroachDB uses the Pebble storage engine. If you haven't already, we recommend reading the Architecture Overview.Įach CockroachDB node contains at least one store, specified when the node starts, which is where the cockroach process reads and writes its data on disk.
