> If some replicas continue doing work after the coordinator responds to the client (e.g. writing at CL.ONE with RF=3), those trace events will not have a source_elapsed field, leading to the following error in cqlsh:
> {noformat}
> Traceback (most recent call last):
>   File "bin/cqlsh", line 822, in onecmd
>     self.handle_statement(st, statementtext)
>   File "bin/cqlsh", line 863, in handle_statement
>     return self.perform_statement(cqlruleset.cql_extract_orig(tokens, srcstr))
>   File "bin/cqlsh", line 898, in perform_statement
