InnoDB and TokuDB on AWS

 | February 1, 2016 |  Posted In: Benchmarks, InnoDB, TokuDB

In a recent post, Vadim compared the performance of Amazon Aurora and Percona Server on AWS. This time, I am comparing write throughput for InnoDB and TokuDB, using the same workload (sysbench oltp/update/update_non_index) and a similar set-up (r3.xlarge instance, with general purpose ssd, io2000 and io3000 volumes) to his experiments. All the runs used 16 threads for sysbench, and the following […]

 | December 16, 2015 |  Posted In: InnoDB, Insight for DBAs, MySQL

We work on data recoveries quite often. In many cases, we recover table structures from the .frm files because there was no backup available.

Recently Aphyr (Kyle Kingsbury) published https://aphyr.com/posts/327-call-me-maybe-mariadb-galera-cluster The article is technically valid, I am not going to dispute a conclusion Aphyr made, but it is also quite technically involved, so users who just jump to conclusion may get the wrong impression and we’re left with more questions than ever.

Update on the InnoDB double-write buffer and EXT4 transactions

 | June 17, 2015 |  Posted In: Benchmarks, Hardware and Storage, InnoDB, MySQL

Many people commented on the post mentioning […]
