Release 1.14.0 (Brazil)

Released on 2014-08-20

The highlights of this release are:

  • Support for storing binary data
  • Seamless database migration
  • Support for Python 3

Compatibility

Backwards-compatible changes

Data files from RethinkDB versions 1.13.0 onward will be automatically migrated to version 1.14.x. As with any major release, back up your data files before performing the upgrade. If you are upgrading from a release earlier than 1.13.0, follow the migration instructions before upgrading:

http://rethinkdb.com/docs/migration/

Secondary indexes now use a new format; old indexes will continue to work, but you should rebuild indexes after upgrading to 1.14.x. A warning about outdated indexes will be issued on startup.

Indexes can be migrated to the new format with the rethinkdb index-rebuild utility. Consult the troubleshooting document for more information:

http://rethinkdb.com/docs/troubleshooting#my-secondary-index-is-outdated

API-breaking changes

The return_vals optional argument for insert, delete and update has been changed to return_changes, and works with all write operations (previously, this only worked with single-document writes). The returned object is in a new format that is backwards-incompatible with previous versions. Consult the API documentation for these commands for details:

http://rethinkdb.com/api/javascript/insert
http://rethinkdb.com/api/javascript/delete
http://rethinkdb.com/api/javascript/update

The upsert optional argument to insert has been replaced with conflict and new allowed values of error, replace or update. This is a backwards-incompatible change. Consult the API documentation for more information.

  • Queries are automatically parallelized and distributed
  • Lock-free operation via MVCC concurrency

Limitations

There are a number of technical limitations that aren't baked into the architecture, but were not resolved in this release due to time pressure. They will be resolved in subsequent releases.

  • Write requests have minimal batching in memory and are flushed to disk on every write. This significantly limits write performance, expecially on rotational disks.
  • Range commands currently don't use an index.
  • The clustering system has a bottleneck in cluster metadata propagation. Cluster management slows down significantly when more than sixteen shards are used.
