Hi, We're trying to confirm on a counter write that the entire partition is read from disk vs. just the row and column of the partition to increment. We've trade the code to this line <https://github.com/apache/cassandra/blob/cassandra-3.7/src/java/org/apache/cassandra/db/SinglePartitionReadCommand.java#L518>. It looks like the code only uses a filter on the partition for reading if the read does not involve collections or counters. Can anyone familiar with the source code confirm if this is true and whether we're looking at the right lines of code that show what data is read from disk (or from an internal cache)?
Thanks, Paul
