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.
Azure PostgreSQL Database is a relational database service based on the open-source Postgres database engine. It is a fully-managed, enterprise-ready community PostgreSQL database as a service that can handle mission-critical workloads with predictable performance, security, high availability, and dynamic scalability.
You can ingest data from your Azure PostgreSQL database using Hevo Pipelines and replicate it to a Destination of your choice.
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.
Azure PostgreSQL does not support logical replication on read replicas. To enable log-based replication, you must select the master database instance.
For new Azure PostgreSQL databases, SSL connections may be enforced. To turn off SSL connections, do the following:
Log in to the Azure Portal.
Under Resources, Recent tab, select the database for which you want to turn off the SSL connection mode. For example, postgresql-docs in the image below.
In the left navigation pane of your <Database Name> page, under Settings, click Connection security.
In the right pane, under SSL settings, toggle the Enforce SSL connection option to DISABLED and click Save.
The data type Array in the Source is automatically mapped to Varchar at the Destination. No other mapping is currently supported.
If your Source data has indexes (indices) and constraints, you must recreate them in your Destination table, as Hevo does not replicate them from the Source. It only creates the existing primary keys.
Hevo does not set the
__hevo_marked_deletedfield to True for data deleted from the Source table using the TRUNCATE command. This could result in a data mismatch between the Source and Destination tables.
