Shawn Kumar created CASSANDRA-9815: -------------------------------------- Summary: Tracing doesn't seem to display tombstones read accurately Key: CASSANDRA-9815 URL: https://issues.apache.org/jira/browse/CASSANDRA-9815 Project: Cassandra Issue Type: Bug Components: Tools Reporter: Shawn Kumar Priority: Minor Attachments: tracescreen.png
It seems that where tracing [once|http://stackoverflow.com/questions/27063508/how-to-get-tombstone-count-for-a-cql-query] tracked how many tombstones were read in a query, it no longer happens. Can reproduce with the following: 1. Create a simple key, val table. 2. Insert a couple rows 3. Flush 4. Delete a row, add an additional couple rows 5. Flush 6. Try to query deleted row or select *. In the trace it never mentions reading a tombstoned cell, no matter what. Instead you get a line like the following: "Read 0 live and 0 tombstone cells [SharedPool-Worker-3]". Attached is a screenshot of the trace. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
