v2.3.0

This release includes the following:

Features:

• Push down ORDER BY to remote hdfs servers.
  If possible, consider a path that adds the ORDER BY clause to the remote SQL so that we get the ordered result set from the foreign server itself. It might help us to have an efficient merge join.

• Push down LIMIT/OFFSET to remote hdfs servers.
  Wherever applicable, perform LIMIT and OFFSET operations on the remote server. This reduces network traffic between local PostgreSQL and remote HDFS servers.

v2.2.0

This release includes the following:

Features:

• Push down aggregates to remote HDFS servers.
  Push aggregates to the remote HDFS server instead of fetching all
  of the rows and aggregating them locally. This gives a very good
  performance boost for the cases where aggregates can be pushed down.

• Add support for PostgreSQL 15 and EDB Postgres Advanced Server 15.

• Remove support for v9.6.

Other improvements and Fixes:

• Add support for the NUMERIC datatype.
• Remove some extraneous code from function deparse logic.
• Do not push expressions evaluating as non-builtin datatype.
• Improve some test-coverage

v2.1.0

This release includes the following feature:

Join Push-down - If we have a join between two foreign tables from the same remote server, push that join down to the remote server instead of fetching all the rows for both the tables and performing a join locally.

Support for PostgreSQL 14 and EDB Postgres Advanced Server 14.
