Dump the jvm heap，analysis the the heap and find which query(s) cost so
many memory？
In my ever bad case，the RS crashed for Long GC pauses because of a big

use case - especially if w
I think Benedict was asking if it would be possible to add the capability.
Actually the old product data doesn't have to die, Benedict. Set VERSIONS > 1
in your schema. The old cell version(s) carrying the old label set will still
be there, accessible with a Scan that asks for N versions instea
