    CockroachDB - the open source, cloud-native distributed SQL database.

    Uff... Let's go give a look at the licenses: https://github.com/cockroachdb/cockroach/blob/master/LICENSE

    So many licenses, including the Business Source License which is non-free license.

    Also there's this CockroachDB Community License (CCL), which I guess is a made-up license that's going to include some whatever terms.

    I might still accept this mix of licenses however I can't find the definition of "foundational features" -- what do I "lose" by using the OSS version instead of one of their managed offerings?

    From a quick overview, it's soft-no from me (in the sense that it probably wouldn't be my first choice).

  • rosettable

    service to add postgres triggers on mysql CRUD events

    Shameless plug: check out [Rosettable https://github.com/francoisp/rosettable]. Brings Postgres triggers and notifies to your MySQL schema, with it you can organize a smooth transition. Using MySQL_fdw you can use your current MySQL schema with the above you can know when a client interacted directly with MySQL; all the while you add some nice jsonb and Plpgsql and transition out of MySQL incrementally. Don’t rewrite, write onward

  • Scout APM

    Less time debugging, more time building. Scout APM allows you to find and fix performance issues with no hassle. Now with error monitoring and external services monitoring, Scout is a developer's best friend when it comes to application development.

  • gh-ost

    GitHub's Online Schema Migrations for MySQL

    Online schema change solutions have been around for over the past decade and are commonly used to ALTER TABLE with no downtime (or with minimal interruption) on the largest deployments of MySQL today.

    The two most common solutions are pt-online-schema-change and gh-ost, and if you are running MySQL today and still running direct ALTER TABLE suffering outage, then you're in for a pleasant change.

    On top of that, most MySQL ALTER TABLE operations with InnoDB tables support non-blocking, lockless operation as well. My main concern with these is that they're still replicated sequentially leading to replication lags.

    MySQL is also slowly adding "Instant DDL", currently still limited to just a few types of changes.

    Disclosure: I authored gh-ost (at GitHub), oak-online-alter-table (the original schema change tool) and am a maintainer for Vitess and working on online schema changes in Vitess.

  • mysql-5.6

    Facebook's branch of the Oracle MySQL v5.6 database. This includes MyRocks.

    as we are all discussing the pros and cons of various DBs, my favourite MySQL feature has to be the pluggable storage engines. Being able to support both InnoDB and RocksDB backed tables in the same database is wonderful. Just today I made use of the MyRocks storage engine's handy TTL [1] feature instead of a tedious delete & optimise scheduled job


  • duckduckgo-locales

    Translation files for duckduckgo.com

    That’s good to know!

    If the first result is not reputable, that’s still a smell (but a different kind of smell) for MySQL. https://duckduckgo.com/?q=innodb+vs+myisam

  • yugabyte-db

    The high-performance distributed SQL database for global, internet-scale apps.
