Match multiple entries in container_usage.csv to the entries in container_meta.csv with same container_id

As mentioned in title, here is an example: in container_meta.csv, we have entries about c_1 with various timestamp, thus I expect that there are three instances of container "c_1" is launched; ;correspondingly in container_usage.csv, we obtain the run time details of those instances of "c_1".

It's straightforward that the entries whose time stampe in container_usage.csv less than 287942 are clearly matched to the first launched instance in container_meta.csv. But when the time stamp comes to 764780, which instance in container_meta.csv could be matched?
Thanks!
