Instaclustr’s automated systems are constantly monitoring the growth of Instametrics, and periodically it reaches a threshold where TechOps determines it requires more storage.
When this happens, they contact the Engineering team to get permission to add more nodes.
On one of these occasions, our team of experts in TechOps looked more closely at our usage of Cassandra and how it has changed over the years, to see if there were ways to further optimize it.
And we found a way to reduce our disk usage by over 20%, with just a change to our data schema.
Read on to see what they did and how they were able to save a good amount of disk space.
