hongbin ma commented on KYLIN-2598:
-----------------------------------
added a threshold called kylin.query.translated-in-clause-max-size, default
value
> Should not translate filter to a in-clause filter with too many elements
> ------------------------------------------------------------------------

> Key: KYLIN-2598
> URL: https://issues.apache.org/jira/browse/KYLIN-2598
> Project: Kylin
> Issue Type: Improvement
> Reporter: hongbin ma
> Assignee: hongbin ma
> Fix For: v2.1.0
>
>
> In
> org.apache.kylin.dict.BuiltInFunctionTransformer#translateFunctionTupleFilter
> we will translate builtin-functions like upper,lower,like to in-clause
> filters.
> (KYLIN-993)
> The approach is In-clause filter will soon become in-efficient when too many
> elements accumulate in the in-clause. Suggest to set a threshold so that when
> there're more elements than this threshold, the translation will abort
