PG Columnar Store Extension cstore_fdw 1.2 Released

cstore_fdw 1.2, an open source columnar store extension for PostgreSQL, has been released by Citus Data. Widely used, cstore_fdw can significantly decrease query times for analytic queries, and compress large event datasets to save disk space.

Changes in this release include:

·        Support for “INSERT INTO … SELECT …” – enables loading of data directly into cstore from regular PostgreSQL tables

·        Support for “COPY TO” – enables use of the COPY command to cope the contents of a cstore table to a file

·        Improved Memory Usage – as much as 90% less memory usage in some scenarios

Further information on cstore_fdw can be found on the Citus Data website at https://www.citusdata.com/citus-products/cstore-fdw and on GitHub at https://github.com/citusdata/cstore_fdw/blob/master/README.md.
