Coming out of #31, I think it makes sense to enable fielddata for columns of type 'phrase' and 'phrase_array'.
Doing so will enable
zdb_tally()andzdb_significant_terms()to work with such fields, which could be extremely useful for building word-clouds (or whatever) over columns that contain "short text".The downside will be that ES will keep a fielddata cache for these fields, and if the data is dense (and if there's a lot of it), this could have negative impacts to ES' memory management. But ya gotta pay to play.
