Delta Lake

An HMS or Glue table is treated as Delta Lake when its properties contain spark.sql.sources.provider with value DELTA, case-insensitively. Lakelet loads the table from its table location and reads the Delta transaction log through delta-rs.

Delta Lake support is not yet complete and should be treated as experimental.

Data Types

The same as delta-rs.

Metadata Table

Delta Lake metadata tables are not currently exposed by Lakelet.
