Dan Burkert commented on KUDU-1452:
-----------------------------------
Sounds good to me. I can't think of an efficient way to do it either, but
agree that it's probably worth pushing down into the tablet server for
applications which have to have it. In the case of prefix matches
("something%"), we could rewrite the query as a range predicate, which could
potentially be faster.
> Add predicate to allow scan based on COLUMN LIKE '%val%'

> 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.
