Amazon RDS PostgreSQL

Last updated on Nov 13, 2023

Starting Release 2.18.2, Hevo will stop supporting XMIN as a query mode for all variants of the PostgreSQL Source. As a result, you will not be able to create new Pipelines using this query mode. This change does not affect existing Pipelines. However, you will not be able to change the query mode to XMIN for any objects currently ingesting data using other query modes.

You can set up, operate, and scale PostgreSQL deployments in the cloud with Amazon RDS. Amazon RDS for PostgreSQL gives you access to the capabilities of the familiar PostgreSQL database engine. This means that the code, applications, and tools you already use today with your existing databases can be used with Amazon RDS.

You can ingest data from your Amazon RDS PostgreSQL database using Hevo Pipelines and replicate it to a Destination of your choice.


Source Considerations

  • If you add a column with a default value to a table in PostgreSQL, entries with it are created in the WAL only for the rows that are added or updated after the column is added. As a result, in the case of log-based Pipelines, Hevo cannot capture the column value for the unchanged rows. To capture those values, you need to:

    • Restart the historical load for the respective object.

    • Run a query in the Destination to add the column and its value to all rows.

Limitations

  • The data type Array in the Source is automatically mapped to Varchar at the Destination. No other mapping is currently supported.

  • Hevo does not support data replication from foreign tables, temporary tables, and views.
