    Return an instance of DeltaColumnBuilder to specify a column. Refer to DeltaTableBuilder for examples and DeltaColumnBuilder detailed APIs.

    Note: This uses the active SparkSession in the current thread to read the table data. Hence, this throws error if active SparkSession has not been set, that is, SparkSession.getActiveSession() is empty.

  8. def convertToDelta(spark: SparkSession, identifier: String): DeltaTable

    Create a DeltaTable from the given parquet table.

    Create a DeltaTable from the given parquet table. Takes an existing parquet table and constructs a delta transaction log in the base path of the table.

    Note: Any changes to the table during the conversion process may not result in a consistent state at the end of the conversion. Users should stop any changes to the table before the conversion is started.

    An Example would be

    io.delta.tables.DeltaTable.convertToDelta(
 spark,
 "parquet.`/path`"
    Since

    0.4.0

  9. def convertToDelta(spark: SparkSession, identifier: String, partitionSchema: String): DeltaTable

    Create a DeltaTable from the given parquet table and partition schema.

    Create a DeltaTable from the given parquet table and partition schema. Takes an existing parquet table and constructs a delta transaction log in the base path of that table.

    Note: Any changes to the table during the conversion process may not result in a consistent state at the end of the conversion. Users should stop any changes to the table before the conversion is started.

    An example usage would be

    io.delta.tables.DeltaTable.convertToDelta(
 spark,
 "parquet.`/path`",
 "key1 long, key2 string")

  10. def convertToDelta(spark: SparkSession, identifier: String, partitionSchema: StructType): DeltaTable

    Create a DeltaTable from the given parquet table and partition schema.

    Create a DeltaTable from the given parquet table and partition schema. Takes an existing parquet table and constructs a delta transaction log in the base path of that table.

    Note: Any changes to the table during the conversion process may not result in a consistent state at the end of the conversion. Users should stop any changes to the table before the conversion is started.

    An example usage would be

    io.delta.tables.DeltaTable.convertToDelta(

 "parquet.`/path`",
 new StructType().add(StructField("key1", LongType)).add(StructField("key2", StringType)))
