Re: Question about whether or not to create an Encoded Vector Index (EVI)

Eric

Remember that even if you create a recommended index, it might not be used for the access plan. In fact, it might help in deciding that another index is better to use.

I forget whether last date used attribute of an LF (EVI index type) is updated when the optimizer uses it in its process. I do remember some discussions about that, to see whether to get rid of unused objects like indexes.

Regards
Vern

I thank you, Michael Schutte. Your comment about EVI is easier to
understand than the IBM White Paper (that I posted the other day). I
will create some Encoded Vector Indexes next, based on the Navigator
recommendations.
