Update Statistics in IndexOptimize

[Nehamnsu]

Does the @UpdateStatistics parameter in IndexOptimize update stats with full scan or based on some sampling% on a table?

When i checked the CommandLog table for the commands that were run, I didn't see any specification "with Full Scan"

@Nehamnsu, by default it is updating the statistics with a default sample.

You can use the parameter @StatisticsSample, if you want to use another sample.

@StatisticsSample = 100 is equal to FULLSCAN.
