Percona Live Call for Papers

Percona Live Call for PapersWe are extending the Percona Live Open Source Database Conference Europe 2017 call for papers deadline to Monday, July 24, 2017. Get your submissions in now!

Between our Conference Committee working hard to review all the outstanding talk ideas, and the many community requests for more time, we didn’t want to shortchange any of our applicants. If you procrastinated too long, didn’t complete your talk submission or just plain forgot to submit, this is your reprieve! You have one extra week to pull together a proposal for a talk on open source databases at Percona Live Europe 2017.

The theme of Percona Live Europe 2017 is “Championing Open Source Databases.” There are sessions on MySQL, MariaDBMongoDB and Other Open Source Database technologies, including time series databases, PostgreSQL and RocksDB. Are you:

  • Working with MongoDB as a developer?
  • Creating a new MySQL-variant time series database?
  • Deploying MariaDB in a novel way?
  • Using open source database technology to solve a business issue?

Share your open source database experiences with peers and professionals in the open source community! We invite you to submit your speaking proposal for breakout, tutorial or lightning talk sessions:

  • Breakout Session. Broadly cover a technology area using specific examples. Sessions should be either 25 minutes or 50 minutes in length (including Q&A).
  • Tutorial Session. Present a technical session that aims for a level between a training class and a conference breakout session. Encourage attendees to bring and use laptops for working on detailed and hands-on presentations. Tutorials will be three or six hours in length (including Q&A).
  • Lightning Talk. Give a five-minute presentation focusing on one key point that interests the open source community: technical, lighthearted or entertaining talks on new ideas, a successful project, a cautionary story, a quick tip or demonstration.

Submit your talk ideas now.

PLEASE NOTE: We have a new call for papers system that requires everyone to register for a new account. You can save proposals as drafts and edit them later. Once a proposal is submitted, it is final. You can NOT change a proposal once submitted.

Percona XtraDB Cluster 5.7.18-29.20 is now available

Percona XtraDB Cluster 5.7

Percona XtraDB Cluster 5.7Percona announces the release of Percona XtraDB Cluster 5.7.18-29.20 on June 2, 2017. Binaries are available from the downloads section or our software repositories.

NOTE: You can also run Docker containers from the images in the Docker Hub repository.

NOTE: Due to new package dependency, Ubuntu/Debian users should use apt-get dist-upgrade or apt-get installpercona-xtradb-cluster-57 to upgrade.

Percona XtraDB Cluster 5.7.18-29.20 is now the current release, based on the following:

All Percona software is open-source and free.

Fixed Bugs

  • PXC-749: Fixed memory leak when running INSERT on a table without primary key defined and wsrep_certify_nonPK disabled (set to 0).

    NOTE: We recommend you define primary keys on all tables for correct write-set replication.

  • PXC-812: Fixed SST script to leave the DONOR keyring when JOINER clears the datadir.

  • PXC-813: Fixed SST script to use UTC time format.

  • PXC-824: Fixed graceful shutdown of Percona XtraDB Cluster node to wait until applier thread finishes.

Other Improvements

  • PXC-819: Added five new status variables to expose required values from wsrep_ist_receive_status and wsrep_flow_control_interval as numbers, rather than strings that need to be parsed:

    • wsrep_flow_control_interval_low
    • wsrep_flow_control_interval_high
    • wsrep_ist_receive_seqno_start
    • wsrep_ist_receive_seqno_current
