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.
