Video is forthcoming.

Release

This release contains AMD and ARM FeatureBase binaries for macOS (darwin) and Linux.

The tarball for each architecture includes a directory for FeatureBase and an IDK directory for consumers for CSV, Github, Kafka and SQL.

Highlights

The SQL3 feature flag has been removed, and the SQL3 is now the default. We've added new functions such as time quantum and aggregate functions.

NOTE: We use "SQL3" to refer to the new SQL support for FeatureBase. "SQL3" does not refer to a particular flavor of SQL.

Resolved Bugs

  • FB-1887 fb_exec_requests query group by not working
  • FB-1909 Bug in backup and backup_tar field key translation
  • FB-1912 Restore uses an obnoxious amount of memory
  • FB-1954 Weird capitalization column misrepresentation bug (Nope, not capitalization)

Task

  • FB-1558 Implement semantics to support inserts into time quantum fields
  • FB-1654 Implement select on a timequantum nested table

  • FB-1996 Limit memory allowed while creating backup
  • FB-2013 Remove SQL3 feature flag

Active Bugs

None

Issues

  • Dashboard UI still isn't showing metrics on imports (previously a bug, but we're kicking around getting rid of the current dashboard, so we moved it here)
  • Delete can delete records it probably shouldn't (this is limited to pending inserts and is a hard problem with filtering we're advertising here while we investigate)

Comments

The previously required flag for enabling full SQL support is no longer required and this message will be removed on the next release.

Keep in mind we don't support all SQL statements, yet.
