To see the list of features and bug-fixes planned for next releases, see our [development roadmap][roadmap]. Requested Features ------------------ * Improve write performance * Improve read performance * Add checksum logic * Add new compression methods * Enable INSERT/DELETE/UPDATE * Enable users other than superuser to safely create columnar tables (permissions) * Transactional semantics * Add config setting to make pg\_fsync() optional Known Issues ------------ * Copy command ignores NOT NULL constraints. * Planning functions don't take into account average column width. * Planning functions don't correctly take into account block skipping benefits. * On 32-bit platforms, when file size is outside the 32-bit signed range, EXPLAIN command prints incorrect file size. * If two different columnar tables are configured to point to the same file, writes to the underlying file aren't protected from each other. * When a data load is in progress, concurrent reads on the table overestimate the page count. * We have a minor memory leak in CStoreEndWrite. We need to also free the comparisonFunctionArray. * block\_filtering test fails on Ubuntu because the "da\_DK" locale is not enabled by default. * We don't yet incorporate the compression method's impact on disk I/O into cost estimates. * CitusDB integration errors: * Concurrent staging cstore\_fdw tables doesn't work. * Setting a default value for column with ALTER TABLE has limited support for existing rows.
