Citus Data is excited to announce the release of cstore_fdw 1.2, which is available on GitHub at https://github.com/citusdata/cstore_fdw. Cstore_fdw is Citus Data’s open source columnar store extension for PostgreSQL.

The changes in this release include:

  • INSERT INTO … SELECT … support. You can now use the “INSERT INTO cstore_table SELECT …” syntax to load data into a cstore table directly from regular tables.
  • COPY TO support. You can now use the COPY command to copy the contents of a cstore table to a file.
  • Improved Memory Usage. Some of our users reported that cstore_fdw was using too much memory when the number of columns was high. This version of cstore_fdw uses memory more efficiently, resulting in up to 90% less memory usage.

For installation and update instructions, please see cstore_fdw’s page in GitHub.

To learn more about what’s coming up for cstore_fdw see our development roadmap.
