Pebble

Free plan Self-hosted

What Pebble is

Pebble is a free, open-source Go key-value store for self-hosted applications, built around the performance and storage needs of CockroachDB. Its listed capabilities include checkpoints, indexed batches, snapshots, SSTable ingestion, prefix iteration, range-deletion tombstones, and level-based or manual compaction. The project describes faster reverse iteration and a quicker commit pipeline with improved concurrency compared with RocksDB. Pebble became CockroachDB’s default storage engine in v20.2, released in November 2020, and the README says it is used in production at scale. Its scope intentionally follows CockroachDB’s needs instead of implementing every RocksDB feature. Missing features include backups, column families, transactions, and universal compaction. Compatibility requires care: unsupported RocksDB features may cause silent corruption or incorrect behavior. Pebble v1 may open RocksDB 6.2.1 databases under documented caveats; Pebble v2 and newer cannot open RocksDB-generated databases. Major format upgrades are permanent. The repository uses a BSD-3-Clause license and provides a Go opening example.

Who it suits

It suits Go developers building self-hosted key-value storage around Pebble’s defined feature set. Teams considering RocksDB compatibility should review the unsupported-feature and format-version limits first.

What it does well

Open-source BSD-3-Clause license
Go key-value store for self-hosting
Checkpoints, snapshots, batches, and compaction
Used as CockroachDB’s default storage engine
Production use described at scale

What to know first

No backups, column families, or transactions
No universal compaction
RocksDB compatibility has version limits
Unsupported RocksDB features may corrupt data

Verdict

Pebble offers a focused Go storage engine with a substantial listed feature set and CockroachDB production history. It is most appropriate when its narrower scope and compatibility rules match the application.
