Fast Updates with TokuDB
+4 Vote Up -0Vote Down

With TokuDB v6.6 out now, I’m excited to present one of my favorite enhancements: fast updates with TokuDB. Update intensive applications can have their throughput limited by the random read capacity of the storage system. The cause of the throughput limit is the read-modify-write algorithm that MySQL uses when processing update statements. MySQL reads a row from the storage engine, applies the updates to it, and then writes the new row to the storage engine. To address this throughput limit, TokuDB uses a different update algorithm that simply encodes the …

We wanted to take a moment to say thanks to all of our customers and to the wider MySQL and MariaDB community. Today we announced a doubling of our customer base for the year ending December 31, 2012. Significant milestones over the last year included new technology and service partnerships, several awards, rapid hiring, as well as three upgrades to TokuDB®. We even dabbled in some MongoDB benchmarks. And to fuel continued growth in 2013, we secured additional venture capital funding last November.

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 …

1 Billion Insertions – The Wait is Over!
+4 Vote Up -0Vote Down

iiBench measures the rate at which a database can insert new rows while maintaining several secondary indexes. We ran this for 1 billion rows with TokuDB and InnoDB starting last week, right after we launched TokuDB v5.2. While TokuDB completed it in 15 hours, InnoDB took 7 days.

The results are shown below. At the end of the test, TokuDB’s insertion rate remained at 17,028 inserts/second whereas InnoDB had dropped to 1,050 …
