Challenges of Big Databases with MySQL – IOUG Presentation
+3 Vote Up -0Vote Down

 

 

Many database management tasks become difficult as you move from millions of rows and gigabytes of data to billions of rows and terabytes of data. Such tasks include ingesting data while maintaining indexes; changing schemas without downtime; and supporting connections, replication, and backup. For some scaling problems (connections and replication), MySQL® is better than most of the competition. For others, such as indexing, schema changes, and backup, MySQL has typically been harder to use. Fortunately, the tasks MySQL does well are in its core, whereas the tasks that are more difficult can be solved with storage engine plug-ins.

This week, I was at Percona Live, and it was a lot of fun! I even got to give a talk on write optimization techniques (not just ours), that I’m told will be online soon.

But if you missed that, or even if you didn’t, I’m still in the valley until Monday night. I’ll be speaking very briefly, and fielding questions this Monday, April 16th, at 6PM, at the Silicon Valley NewSQL group’s meetup in Sunnyvale. It’s shaping up to be a great crowd—Amazon, Microsoft, Clustrix, VoltDB, Drizzle, and many others will be there. So if you’re at all

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. The length of the log is a function of the time since the last checkpoint for TokuDB and a more complicated function of the workload for InnoDB. And replaying the log is single threaded. So

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 that post for experimental details.

But first, what are the changes? TokuDB compresses large blocks

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 master has an average transactions per second (tps) that is higher than what the slave can handle, the slave will fall further and further behind. If the slaves are being used to distribute read workload, for example, the

Announcing TokuDB v6.0: Less Slave Lag and More Compression
+1 Vote Up -0Vote Down

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

This version offers feature and performance enhancements over previous releases, support for XA (two-phase transactional commits), better compression, and reduced performance variability associated with checkpointing. 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 new features and performance, so here’s an overview of what’s in store.

Extra features planned for MariaDB 5.5 will be pushed into future releases.

As with any alpha release, MariaDB 5.5.20-alpha should not be used on production systems.

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 inserts/second. That is a difference of over 16x. Our complete set of benchmarks for TokuDB v5.2 can be found here.

Announcing new features in MariaDB

We have lately been talking about some upcoming features that we feel are important to MariaDB users, because the corresponding ones that will be provided with MySQL will be incompatible with MariaDB and closed source.

We’re happy to announce the following:

  • The next version of MariaDB, version 5.2.10 will include an open source PAM Authentication Plugin. MariaDB 5.2.10 is scheduled for release next week.
  • A Windows Authentication Plugin is in development and QA currently and will be part of MariaDB 5.2.11, which is scheduled for release before Christmas.
  • MariaDB 5.5 will include both of the above plugins and an open source thread pool implementation. The soon-to-be-launched first version however will not include the thread pool.

With the release of TokuDB v5.0 last March, we delivered a powerful and agile storage engine that broke through traditional MySQL scalability and performance barriers. As deployments of TokuDB have grown more varied, one request we have repeatedly heard from customers and prospects, especially in areas such as online advertising, social media, and clickstream analysis, is for improved performance for multi-client workloads.

Tokutek is now pleased to announce limited beta availability for TokuDB v5.2. The latest version of our flagship product offers a significant improvement over TokuDB v5.0 in multi-client scaling as well as performance gains in point queries, range queries, and trickle load speed. There are a host of other smaller changes and improvements that are detailed in our release notes (available to beta participants).
