In this blog post, we’ll discuss the ins and outs of Percona Server 5.7 parallel doublewrite.

After implementing parallel LRU flushing as described in the previous post, we went back to benchmarking. At first, we tested with the doublewrite buffer turned off. We wanted to isolate the effect of the parallel LRU flusher, and the results validated the design. Then we turned the doublewrite buffer back on and saw very little, if any, gain from the parallel LRU flusher. What happened? Let’s take a look at the data:

We see that the doublewrite buffer mutex is gone as expected and that the top waiters are the rseg mutexes and the index lock (shouldn’t this be fixed in 5.7?). Then we checked PMP:

2678 nanosleep(libpthread.so.0),...,buf_LRU_get_free_block(buf0lru.cc:1435),...
867 pthread_cond_wait,...,log_write_up_to(log0log.cc:1293),...
396 …

Some of the most common questions asked by our users are regarding MariaDB support in Docker, and in particular how it can be used in specific development or production deployments. This series of articles will try to cover a few Docker and MariaDB use cases.

Why choose Docker for MariaDB?

• Docker containers can be used to test, deploy and release applications within any environment.
• Docker deployments can be automated easily, creating deployment environments and reproducing them easily in staging and production.
• Docker is lightweight virtualization. Hypervisors are not needed, and a MariaDB Docker container should perform just as well as a normal MariaDB installation without any noticeable overhead.
• Docker is agnostic - once you’ve installed Docker on your OS, the instructions for running containers are …

Before data insertion, updates, deletes etc, database management systems that support foreign keys (like MySQL) make sure you do not introduce any inconsistencies. So, you need to make sure you're not leaving orphan records behind in child tables.
