NoSQL is Great, But You Still Need Indexes

I’ve said it before, and, as is the nature of these things, I’ll almost certainly say it again: your database performance is only as good as your indexes.That’s the grand thesis, so what does that mean? In any DB system — SQL, NoSQL, NewSQL,...

TokuDB v6.0: Even Better Compression

A key feature of our new TokuDB v6.0 release, which I have been blogging about this week, is compression. Compression is always on in TokuDB, and the compression we’ve achieved in the past has been quite good. See a previous post on the 18x compression achieved...

TokuDB v6.0: Getting Rid of Slave Lag

Master/slave replication is an important tool that gets used in many ways: distributing read loads among many slaves for performance, using a slave for backups so the master can handle live load, geographically distributed disaster recovery, etc. The Achilles’...

Query Planner Gotchas

Indexes can reduce the amount of data your query touches by orders of magnitude. This results in a proportional query speedup. So what happens when you define a nice set of indexes and you don’t get the performance pop you were expecting? Consider the following...

Percona Live, NYC

Yesterday, Percona held Percona Live NYC, which they describe as an “intensive one-day MySQL summit.” They meant it. It was like drinking from a firehose. There was too much for me to give a complete report, so I’d like to highlight two sessions that...
