This topic describes how to convert a Parquet table in Hive or Spark SQL to a Delta table.

Examples:
  • Scala 
    import io.delta.tables. _
// Convert a non-partitioned table to a Delta table.
val deltaTable = DeltaTable.convertToDelta(spark, "parquet.`/path/to/table`")
// Convert a partitioned table to a Delta table.
val partitionedDeltaTable = DeltaTable.convertToDelta(spark, "parquet.`/path/to/table`", "date string")
  • SQL 
    -- Convert a non-partitioned table to a Delta table.
CONVERT TO DELTA parquet_table;
-- Convert a partitioned table to a Delta table.
CONVERT TO DELTA parquet_table PARTITIONED BY (date STRING);
