> But my concern is, to provide a good use experience and functionality, we may need a bunch of "gap-filling" functions. Like filling it with null, filling it with the last value, filling it with the last value if the gap is less than 1 day otherwise left blank etc. >I'm not sure if these "time-series functions" is also useful to other users of DataFusion (but it might be fine as PostgreSQL also provides such utils). @alamb I also have this concern, some functions specified in `time-series` maybe not compatible with PG, and they maybe not useful to other user who use datafusion just as the PG. -- This is an automated message from the Apache Git Service.
