TokuDB v6.0: Frequent Checkpoints with No Performance Hit
+0 Vote Up -0Vote Down

Checkpointing — which involves periodically writing out dirty pages from memory — is central to the design of crash recovery for both TokuDB and InnoDB. A key issue in designing a checkpointing system is how often to checkpoint, and TokuDB takes a very different approach from InnoDB. How often and how much InnoDB checkpoints is complicated, but under certain workloads it can be relatively infrequent. In contrast, TokuDB runs a complete checkpoint starting one minute after the last one ended.

Frequent checkpoints make for fast recovery. Once MySQL crashes, the storage engine needs to replay the log to get back to a correct state. …

TokuDB v6.0: Even Better Compression
+1 Vote Up -0Vote Down

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 by TokuDB v5.0 on one benchmark. In our latest release, we’ve updated the way compression works and got 50% improvement on compression.

I decided to present numbers on the same set of data as the old post, so see …

TokuDB v6.0: Getting Rid of Slave Lag
+1 Vote Up -0Vote Down

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’ Heal of slave performance is that slave workloads are single-threaded. The master can have many clients inserting, updating, querying, whereas the slave has only one insertion client: the master. InnoDB single-client performance is much slower than its multi-client performance, which means that the bottleneck in a master/slave system is often the rate at which a slave can keep up.

If the …

We are excited to announce TokuDB® v6.0, the latest version of Tokutek’s flagship storage engine for MySQL and MariaDB.

This release also brings TokuDB support up to date on MySQL v5.1, MySQL v5.5 and MariaDB v5.2. There’s a lot of great technical stuff under the hood in this release and I’ll be reviewing the improvements one-by-one over the course of this week.

I’ll be posting more details about the …

Last chance to take part in our MySQL/NoSQL/NewSQL survey
+0 Vote Up -0Vote Down

Thanks to everyone who has already taken part in our survey exploring changing attitudes to MySQL following its acquisition by Oracle and examining the competitive dynamic between MySQL and other database technologies, including NoSQL and NewSQL.

The response has been great and even a quick look at the results makes for interesting reading, particularly in the light of our previous findings which indicated declining MySQL usage.

I am really looking forward to …

Is MySQL usage really declining?

If you’re a MySQL user, tell us about your adoption plans by taking our current survey.

Back in late 2009, at the height of the concern about Oracle’s imminent acquisition of Sun Microsystems and MySQL, 451 Research conducted a survey of open source software users to assess their database usage and attitudes towards Oracle.

The results provided an interesting snapshot of the potential implications of the acquisition and the concerns of MySQL users and even, so I am told, became part …
