Barry Fritchman updated TRAFODION-2140: --------------------------------------- Description: The IUS feature provides the ability to update existing histograms incrementally, rather than doing it all from scratch each time. A persistent sample table is used, which is modified at Update Stats time using a predicate to identify rows modified since the last IUS execution. (was: It has been decided that the Incremental Update Statistics feature should be open source; this JIRA is for porting it to the incubator-trafodion code base from EsgynDB.)
