I've been using cassandra on two nodes where one of them ran out of disk space and went down. When I checked, I've observed the size of size_estimates to be ~30GB.

I've removed sstable files from my data directories and restarted the node. Was curious about the root cause of the problem.

As the name suggests, the size_estimates contains estimates of partition counts and their corresponding size. The estimates are calculated and recorded in the background every 5 minutes.

You haven't provided enough information in your post to determine why the node ran out of space. You'll need to analyse the logs for clues. Cheers!

  • Can you please help me with the cause behind observation (size of size_estimates to be ~30GB) and if you need any information that helps you suggest an approach? – PKS Mar 28 '22 at 09:21
