Follow up question from (^): since segments are not time-partitioned, do hybrid table which need to combine star-indexes use the time-granularity to divide the star-index (ie: allowing for star-index on online to still be efficient?)

while segments need not be strictly time-partitioned, Pinot does store the min-max time for each segment and uses it for pruning segments

🤔 honestly will probably collect these Qs and find a good home for them, going. Thanks for fielding all these questions! I only just realized Pinot was not using strictly time-partitioned data :P

yes, it does not enforce it. Typically offline segments end up being strictly time partitioned while realtime segments are created based on arrival time
