FoundationDB vs TiKV

FoundationDB: Apple's ordered, strictly serializable distributed key-value store, built to have layers on top. TiKV: CNCF-graduated, Raft-replicated transactional key-value store in Rust; the storage layer of TiDB.

key differences

  • TiKV is built for larger datasets (Multi-PB) than FoundationDB (≤ 1 PB).
  • Only FoundationDB has pub/sub.
  • Only TiKV has change data capture, ttl / expiry, compression, time travel.

choose foundationdb for

  • +Metadata stores for larger systems (catalogs, object stores)
  • +Foundation for custom databases and layers
  • +Multi-tenant app backends via the Record Layer
  • +Transactional queues and job systems

choose tikv for

  • +Storage layer for distributed SQL (TiDB)
  • +Metadata for distributed file systems (JuiceFS)
  • +Large-scale transactional key-value services
  • +Redis-protocol or custom data layers needing strong consistency

FoundationDB vs TiKV: FAQ

What is the difference between FoundationDB and TiKV?

FoundationDB: Apple's ordered, strictly serializable distributed key-value store, built to have layers on top. TiKV: CNCF-graduated, Raft-replicated transactional key-value store in Rust; the storage layer of TiDB. TiKV is built for larger datasets (Multi-PB) than FoundationDB (≤ 1 PB). Only FoundationDB has pub/sub. Only TiKV has change data capture, ttl / expiry, compression, time travel.

When should I choose FoundationDB over TiKV?

Choose FoundationDB for metadata stores for larger systems (catalogs, object stores); foundation for custom databases and layers; and multi-tenant app backends via the Record Layer. Choose TiKV for storage layer for distributed SQL (TiDB), metadata for distributed file systems (JuiceFS) and large-scale transactional key-value services.

Is FoundationDB or TiKV more popular?

FoundationDB ranks #54 on the WhichDB Score (36.8/100) and TiKV ranks #148 (20.8/100). Popularity is not fit: check the requirements that matter for your project.

Are FoundationDB and TiKV open source?

Yes. FoundationDB is open source. License: Apache License 2.0. Yes. TiKV is open source. License: Apache License 2.0.
