Percona Server for MySQL Highlights – binlog_space_limit

I think it is often confusing to compare upstream MySQL and Percona Server for MySQL, and some helpful information can be found in the introductory notes. But what does that really mean for an ordinary DBA, especially if none of the known big extra features are important in a particular use case?

In this article, I would like to start a series of short blog posts highlighting small, often less known, but potentially useful features, available in Percona Server for MySQL. Let’s start with a relatively new feature.

Limit the disk space used by binary logs problem

Historically, dealing with binary logs and the disk space used by them was quite challenging. The only thing that let you control this is the …

DDL Queries on Foreign Key Columns in MySQL/PXC

Recently, I received a support request where the customer wanted to convert an INTEGER column to BIGINT on two tables. These tables are related by a foreign key, and it is a 3 node PXC cluster. These tables are 20GB and 82 GB in size and DDL’s on such tables in a production environment is always a challenge. We have options like direct ALTER or using pt-online-schema-change to get this done, but this is a very special case where none of them will be able to do this DDL. To demonstrate why this is so, please follow the table schema and the example below about DDL queries on foreign key columns. In the end, I will discuss an easy workaround, too.

Please take a look at table schema before reading further. In the below schema, the product_catalog_id column from the product_details table refers to catalog_id column from the product_catalog table. Both these fields are INT(11) …
