Description

While working on a different issue, I noticed that Kudu currently has no way to fetch rows from a table based on the COLUMN LIKE '%value%' filter.

Most relational DBs will allow lookups based on something like this:
select c1, c2 from table-a where c3 like '%something%'

I cant think of an efficient way to do this in Kudu, but I think it would still be more efficient than a client fetching all the rows and then doing the filtering.
