[jira] [Commented] (LUCENE-9511) Include StoredFieldsWriter in DWPT
accounting

LUCENE-9511: Include StoredFieldsWriter in DWPT accounting (#1839)
StoredFieldsWriter might consume some heap space memory that
can have a significant impact on decisions made in the IW if
writers should be stalled or DWPTs should be flushed if memory
settings are small in IWC and flushes are frequent. This change adds
RAM accounting to the StoredFieldsWriter since it's part of the
DWPT lifecycle and not just present during flush.

> StoredFieldsWriter might consume some heap space memory that can have a significant impact on decisions made in the IW if writers should be stalled or DWPTs should be flushed if memory settings are small in IWC and flushes are frequent. We should add some accounting to the StoredFieldsWriter since it's part of the DWPT lifecycle and not just present during flush.
> Our nightly builds ran into some OOMs due to the large chunk size used in the CompressedStoredFieldsFormat. The reason are very frequent flushes due to small maxBufferedDocs which causes 300+ DWPTs to be blocked for flush causing ultimately an OOM exception.
