SSD Helm install: bloom compactor error #12710

Closed mzupan closed 6 months ago

mzupan commented 6 months ago

Describe the bug I've tried to enable bloom filters on the SSD helm install. On one test cluster with not a lot of traffic it seems to be working. I made basically the same config changes and getting the following error
