codemysql.org?

Many startups depend on MySQL. Check out the list of keynote speakers from past and present MySQL User Conferences. There are things to make better and new features to add like better support for dynamic schemas (documents) and auto-sharding. But existing deployments aren't in crisis mode and it is being used for new deployments. Maybe I have an agenda...

Everything is awesome

My kids watched the new Lego movie today and spent the rest of the day repeating "Everything is amazing". I spent a few hours reading MongoDB documentation to help a friend who uses it. Everything wasn't awesome for all of us. I try to be a pessimist when reading database documentation. If you spend any time near production then you spend a lot of time...

Legacy isn't a dirty word

Pardon the rant but the winter storm has kept me in a hotel away from home for a few days. I exchanged email this week with someone pitching a solution to a problem I don't have (MySQL failover). But by "I" I really mean the awesome operations team with whom I share an office. The pitch got off to a bad start. It is probably better to compliment the...

Modern databases

What is a modern database? We have some terms that wander between marketing and technical descriptions - NewSQL, NoSQL. We have much needed work on write-optimized database algorithms - Tokutek, LevelDB, RocksDB, HBase, Cassandra. We also get reports of amazing performance.

There might be lost transactions if you use asynchronous replication. You can also lose transactions with synchronous replication depending on how you define lose....

Where are the tests?

I looked at the release notes for 5.6.14 and then my bzr tree that has been upgraded to 5.6.14. I was able to find changes in bzr based on bug numbers. However for the 5 changes I checked I did not see any regression tests. For the record, I checked the diffs in bzr for these bugs: 1731508, 1476798, 1731673, 1731284, 1730289.I think this is where the...

Compression?

There aren't many new files under mysql-test for 5.6.14. Is this compression or something else? Many bugs were fixed per the release notes.diff --recursive --brief mysql-5.6.13 mysql-5.6.14 | grep  "Only in"Only in mysql-5.6.14/man: ndb_blob_tool.1Only in mysql-5.6.14/mysql-test/include: have_valgrind.incOnly in mysql-5.6.14/support-files: mysql.5.6.14.specOnly...
