replace_if_not_null 🔒: Replace columns in an existing row with the corresponding columns in a replacement row, if the column value in the replacement row is not null.
row_below_committed_watermark 🔒: Check whether the given row is below the committed watermark. If so, we may want to treat them as non-existent. This extra step is necessary for TTL-ed tables because:
versions_are_newer_or_equal 🔒: Compare multiple version columns lexicographically. Returns true if new_row has a newer or equal version compared to old_row.
