Table Engines

TiDB Cloud Lake provides several table engines so that you can balance performance and interoperability needs without moving data. Each engine is optimized for a specific scenario—ranging from TiDB Cloud Lake’s native Fuse storage to external data lake formats.

Available Engines

EngineBest ForHighlights
Fuse Engine TablesNative TiDB Cloud Lake tablesSnapshot-based storage, automatic clustering, change tracking
Apache Hive TablesHive metastore dataQuery Hive-managed data stores through external tables
Delta Lake EngineDelta Lake datasetsRead Delta tables in object storage with ACID guarantees

Choosing an Engine

  • Use Fuse when you manage data directly inside TiDB Cloud Lake and want the best storage and query performance.
  • Choose Iceberg when you already manage datasets through Iceberg catalogs and need tight lakehouse integration.
  • Configure Hive when you rely on an existing Hive Metastore but want TiDB Cloud Lake’s query engine.
  • Select Delta to analyse Delta Lake tables in place without ingesting them into Fuse.
