We're happy to have Abigail present at the German Perl Workshop 2026!

Sharding a database, twice richtet sich an Alle und wird in English gehalten.

There comes a time in the life time of a database, the database takes too many resources (be it disk space, number of I/O transactions, or something else) to be handled by a single box.

Sharding, where data is distributed over several identically shaped databases is one technique to solve this.

For a high volume database I used to work with, we hit this limit about a dozen
years ago. Then we hit the limit again two years ago.

In this talk, we will first discuss how we initialized switched our systems to make use of a sharded database, without any significant downtime.
