Scaling PostgreSQL with PgBouncer: You May Need a Connection Pooler Sooner Than You Expect

 | June 27, 2018 |  Posted In: Benchmarks, PostgreSQL

PostgreSQL connection pools

In doing so, we’ll take a look at some of the implications for application […]

I’ve started my long journey from Florianópolis, Brazil, to Santa Clara, California and I type this words while waiting for a connection flight. Next Wednesday, Daniel Guzmán Burgos and I will be presenting in the Percona Live MySQL Conference and Expo (PLMCE). I’m so excited with the new MySQL 101 program that has been added […]

and  | February 26, 2015 |  Posted In: InnoDB, Insight for DBAs, MySQL

If you use Percona Server 5.5 and you have configured it to use multiple buffer pool instances than sooner or later you’ll see the following lines on the server’s error log and chances are you’ll be worried about them:

Worry not as this is mostly harmless. It’s becoming a February tradition for me (Fernando) […]

How to setup a PXC cluster with GTIDs (and have async slaves replicating from it!)

 | February 20, 2015 |  Posted In: GTID, MySQL, Percona XtraBackup, Percona XtraDB Cluster

This past week was marked by a series of personal findings related to the use of Global Transaction IDs (GTIDs) on Galera-based clusters such as Percona XtraDB Cluster (PXC). The main one being the fact that transactions touching MyISAM tables (and FLUSH PRIVILEGES!) issued on a giving node of the cluster are recorded on a GTID set […]

Percona XtraDB Cluster: How to run a 2-node cluster on a single server

 | October 21, 2014 |  Posted In: MySQL, Percona XtraDB Cluster

I reckon there’s little sense in running 2 or more Percona XtraDB Cluster (PXC) nodes in a single physical server other than for educational and testing purposes – but doing so is still useful in those cases.

mysqld_multi: How to run multiple instances of MySQL

 | August 26, 2014 |  Posted In: Insight for DBAs, MySQL, Percona MySQL Support, Percona Server for MySQL, Percona XtraBackup

The need to have multiple instances of MySQL (the well-known mysqld process) running in the same server concurrently in a transparent way, instead of having them executed in separate containers/virtual machines, is not very common. Yet from time to time the Percona Support team receives a request from a customer to assist in the configuration of […]
