------------------------------------------------
Summary: Count all types of tombstones in the read path and the
rows/cells they shadow
Key: CASSANDRA-14149
URL: https://issues.apache.org/jira/browse/CASSANDRA-14149
Project: Cassandra
Issue Type: Improvement
Components: Local Write-Read Paths
Reporter: Alexander Dejanovski
Fix For: 4.x
This ticket is a follow up to CASSANDRA-8527 which aims at reporting row level
tombstones in the read path.
The aim here is to fully categorize the cells/rows that can be shadowed by
range tombstones. Currently, one range tombstone will count for 2 tombstone
cells but as they may shadow thousands if not millions of actual cells, some
latency issues in the local read path may be hard to diagnose.
Based on discussions on the ML, one outcome could be to distinctively count
cell/row/range tombstones and the number of cells/rows shadowed by each type.
