parquetTimestampInMillisecond

A value that specifies the precision of any TIMESTAMP column values that are written to an Amazon S3 object file in .parquet format.

DMS supports the ParquetTimestampInMillisecond parameter in versions 3.1.4 and later.

When ParquetTimestampInMillisecond is set to true or y, DMS writes all TIMESTAMP columns in a .parquet formatted file with millisecond precision. Otherwise, DMS writes them with microsecond precision.

Currently, Amazon Athena and Glue can handle only millisecond precision for TIMESTAMP values. Set this parameter to true for S3 endpoint object files that are .parquet formatted only if you plan to query or process the data with Athena or Glue.

DMS writes any TIMESTAMP column values written to an S3 file in .csv format with microsecond precision.

Setting ParquetTimestampInMillisecond has no effect on the string format of the timestamp column value that is inserted by setting the TimestampColumnName parameter.
