Percona is dedicated to open source software. But recently, open source software has come under attack. Once open source software is being locked away by changing licenses and code that you depended on.

The MySQL 5.7 End of Life is now two months away. Those of you who have waited may be wondering which is the best way to upgrade – an In-Place or Logical upgrade. An In-Place upgrade is where the binaries for 5.7 are replaced with the binaries for 8.0, and the upgrade is made to […]
Open source database architects usually do not implement business logic in their databases. This is in stark contrast to many commercial databases where this is a common practice. In the first case, all the heuristics are kept at the application layer, and the database has little or no effect on the data quality. The second […]

Most of us are lucky that software bugs are a small part of our lives. The ‘things just work’ attitude works for most situations, but occasionally something appears that may seem trivial at first glance may be catastrophic. A bug appeared in MySQL’s recently released 8.0.32 that really caught my attention. This is a prime […]

JSON data and relational databases have traditionally been diametric opposites. One is very free form with minimal rules on the formatting and the other is very strict and formal. So many folks were surprised when relational databases started adding a JSON data type to their products. In this multi-part blog series, we will start with […]
