Inputlookup vs. summary index performance


If I have a bunch of events in a tabular format that I wish to search for various charts on a dashboard, is it faster to input the events with inputlookup or is it better to save them in a summary index and search the index?

Depends on the size of the lookup table. If it's less than 10MB, it's almost certainly faster to use inputlookup because it'll be sitting in memory already.

However bear in mind that you get all sorts of extra flexibility when you have summary indexing going. It's not uncommon for a lookup solution to get replaced down the road by a summary index solution when you need that flexibility. Like when the values start changing over time and you need to report on the changes.

I would think using a summary index would always be faster.
