Benjamin Lerer commented on CASSANDRA-10606:
--------------------------------------------
{quote}Why do you think this is a problem btw?{quote}
My code is checking if a {{ColumnFamilyStore}} is empty or not using the
{{isEmpty()}} method. This method internally rely on
{{Memtable.getOperation()}} to determine if an existing memtable is empty or
not. This number is incremented in {{Memtable.put}} by
{{PartitionUpdate.operationCount()}} which in the case of compact table return
0 even if some static columns are set.
I am not sure that this patch is proper the way to fix the problem but I
believe that something is currently broken in {{PartitionUpdate}} as it should
return a non zero value if it contains an operation that change only the value
of a static column.
