It seems that where tracing once 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
4. Delete a row, add an additional couple rows
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.
