> 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.
