Francisco Guerrero updated CASSSIDECAR-325:
-------------------------------------------
Bug Category: Parent values: Correctness(12982)Level 1 values:
Unrecoverable Corruption / Loss(13161)
Complexity: Normal
Component/s: CDC
Discovered By: User Report
Severity: Normal
Status: Open (was: Triage Needed)
If the fallback value and the actual {{CdcTotalSpaceSetting}} diverge a lot,
there is potential that the {{cdc_raw}} directory does not get cleaned up,
potentially causing mutations to get backed up.
> CdcRawDirectorySpaceCleaner always uses fallback after the first time it is
> queried from system_views.settings

> URL: https://issues.apache.org/jira/browse/CASSSIDECAR-325
> Project: Sidecar for Apache Cassandra
> Issue Type: Bug
> Components: CDC
> Reporter: Francisco Guerrero
> Assignee: Francisco Guerrero
> Priority: Major
>
> In the
> {{org.apache.cassandra.sidecar.tasks.CdcRawDirectorySpaceCleaner#maxUsage}}
> method, the {{cdcTotalSpaceSetting}} value is populated the first time it
> successfully queries the {{system_views.settings}} table. However, subsequent
> successful queries do not return the value if the value has not changed. This
> causes the code to return the configured
> {{fallbackCdcRawDirectoryMaxSizeBytes}} value.
