It is not uncommon that we need to filter out some DBs or Tables while setting up replication. It is important to understand how MySQL evaluates/process the replication filtering rules to avoid the conflicting or confusion while we setting them up.The purpose of this blog is to illustrate the rules and provide some suggestions for best practice.

MySQL provides 3 levels of filters for setting up replication: Binary log, DB and Table. The binlog filters apply on the master to control how to log the changes.

While the DB-level and Table-level filters apply on the slaves, since each table belongs to a schema, the DB-level filters have higher priority than the Table-level ones. Inside the Table-level filters, MySQl will evaluate the options in the order of: …

In last week’s post, Part 1 of 3, we took a look at the JSON data type support added in MySQL 5.7.8. This week, I wanted to look at some of the document-oriented patterns that MongoDB uses so we can see how we might accomplish the same in MySQL.

Historical MySQL Bug#2, opened 12 Sep 2002, states that MySQL Connector/J doesn’t make toast. It hasn’t been fixed for more than 14 years. I’ve finally created a patch for it.

First of all: why only fix this for MySQL Connector/J? We should make sure the server can do this for any implementation! With this fix, now MySQL server (starting with version 5.1) can make toast.

There are few dependences though (see assembled setup picture):
