For this month’s PGSQL Phriday blogging challenge, Tomasz Gintowt asks if people rather use partitioning or sharding to solve business problems. Big Data: Partitioning vs Sharding Adjust Here at Adjust we use both. We also have quite a few databases of all sizes. Let’s look at some examples. We leverage four primary database systems, termed as “Backends”, “Shards”, “Bagger” and “Tracker”. The Backend systems function as intermediate storage of data, anything between hours and weeks....

Currently climbing over 80%, which triggered the alarm in the first place. Not good. However nothing serious as of now, but better investigate now and not wait until Monday. Zabbix Graph: Space utilization The System This particular server has about 3....

In our infrastructure, we mostly use Gentoo for our servers. For anyone who doesn’t know Gentoo: this Linux distribution compiles packages on the server. Upgrades take a bit more time, but on the other hand the installation can be adjusted to specific requirements: need debug symbols on a dev or staging platform? No problem, compile them in. Want to optimize an application? Change the compile parameters and recompile once: done. Like with pre-compiled packages, this approach has ups and downs....

The Ansible collection includes the postgresql_privs module which is used to set or revoke privileges on database objects. So far this can be used in a programmatic way: specify the privileges, but also specify if something should be revoked. To give you an example: Let’s say we have a table users in the database. Now an additional role audit is supposed to have SELECT privileges on this table. You solve this by adding one postgresql_privs task:...
