Better Replication when running both InnoDB and MyRocks (or other Storage-Engines)

Kristian Nielsen is working on a new feature for MariaDB 10.3 and he published very interesting results.  This feature is MDEV-12179: Per-engine mysql.gtid_slave_pos tables.  He writes about replicating twice as fast in the worst case when using two storage engines (InnoDB and MariaRocks in his tests, but could also be InnoDB and TokuDB or TokuDB and MyRocks).  I will let you read all the details

MyRocks and LOCK IN SHARE MODE

In this blog post, we’ll look at MyRocks and the

LOCK IN SHARE MODE

.

Those who attended the March 30th webinar “MyRocks Troubleshooting” might remember our discussion with Yoshinori on 

LOCK IN SHARE MODE

.

I did more tests, and I can confirm that his words are true:

LOCK IN SHARE MODE

 works in MyRocks.

This quick example demonstrates this. The initial setup:

CREATE TABLE t (
id int(11) NOT NULL,
f varchar(100) DEFAULT NULL,
PRIMARY KEY (id)
) ENGINE=ROCKSDB;
insert into t values(12345, 'value1'), (54321, 'value2');

My First Steps with MariaDB 10.2 and RocksDB Storage Engine

Last year I started to explore MyRocks, that is, RocksDB used as a storage engine with MySQL. So far I had to use Facebook's MySQL 5.6 to do this. I could try to use some specific development branches of MariaDB (or maybe even Percona Server) for this, but I preferred to wait until the engine is included into a main branch by the company I work for. Recently this happened, and now you can get RocksDB loaded and working in main MariaDB 10.2 branch. In this blog post I am going to explain how to build it from source and do some basic checks.

I was updating my MariaDB local repository on my Ubuntu 14.04 netbook, with 10.2 branch already checked out (do git checkout 10.2 if …
