if I recall correctly there was a threshold in place that indexes would be rebuild on DML once DML changed more than x-% of data in a table - is that still correct with V.6.2.8 ? Stumbled upon a scenario where someone inserted a few billion records and I´d have thought that the INSERT part would finish and then there would be INDEX REBUILD steps but instead it took place as INDEX INSERT...or did the REBUILD-part only apply to UPDATEs ?
Ok, and since we are not "shifting data around" when INSERTs happen there probably isn´t much to gain if we were to rebuild instead of plainly INSERT´ing ( things like index node splits and the like probably don´t cost much in this case ).
@exa-Uwe : if you get rid of the "AFAIK" , I´ll mark your answer as solution - deal ? 😄
