Pre-emptive eviction of buckets on smartstore ?

agdk — Wed, 17 Apr 2024 08:08:11 GMT

We have a splunk installation with smart store enabled. We have plenty of cache on disk, so we are no near the space padding setting.

I have seen bucket downloads from the S3, and I did not expect that. So my question is, do Splunk pre-emptive evict buckets, even if there are enough space ? I se no documentation that states it does anything else than LRU.

Regards

André

@agdkIf you’re observing bucket downloads from S3 unexpectedly, it might be worth investigating further.. Verify that your SmartStore configuration is correctly set up. Ensure that the cache and cold storage volumes are properly configured.?? Confirm that the space padding setting is appropriately adjusted to avoid unnecessary eviction..??

Yes, it was the padding / max cache size that was the culprit. The calculation I did was wrong.

Thank you
