The MySQL ARCHIVE storage engine – Alternatives
+0 Vote Up -0Vote Down

In my previous post I pointed out that the existing ARCHIVE storage engine in MySQL may not be the one that will satisfy your needs when it comes to effectively storing large and/or old data. But are there any good alternatives? As the primary purpose of this engine is to store rarely accessed data in disk space efficient way, I will focus here on data compression abilities rather then on performance.

The InnoDB engine provides compressed row format, but is it’s efficiency even close to the one from …

MariaDB world record price per row 0.0000005$ on a single DELL R710
+0 Vote Up -0Vote Down

Don't look at an industry benchmark here, it's a real client story.

200 Billion records in a month and it should be transactional but not durable.

For regular workload we use LOAD DATA INFILE into partitioned InnoDB, but here we have estimated 15TB of RAID storage. This is a lot of disks and it can't no more stay inside a single server internal storage.

MariaDB 5.5 come with TokuDB storage engine for compression, but is it possible in the time frame impose by the workload?

We start benchmarking 380G of raw input data files,  6 Billion rows.

What does the ‘Incorrect key file for table’ error mean?
+0 Vote Up -0Vote Down

What does it mean if MySQL returns the ‘Incorrect key file for table’ error for one of my queries? The answer is complicated and depends on which storage engine is returning the error. We have debugged two cases which we describe here.

File system out of space

When running the random query generator, one of the queries failed.

Query: SELECT * FROM (mysql . general_log AS table1 INNER JOIN INFORMATION_SCHEMA . INNODB_BUFFER_PAGE AS table2 
ON ( table2 . SPACE = table1 . user_host ) ) ORDER BY table1 . thread_id LIMIT 168 
failed: 126 Incorrect key file for table …
