[jira] [Created] (IMPALA-9615) Make re2's max_mem option configurable via an Impala startup flag.

             Summary: Make re2's max_mem option configurable via an Impala startup flag.
                 Key: IMPALA-9615
                 URL: https://issues.apache.org/jira/browse/IMPALA-9615
             Project: IMPALA
          Issue Type: Improvement
    Affects Versions: Impala 3.4.0
            Reporter: Attila Jeges


Right now Impala always uses the default max_mem value for re2 regexp pattern matching.

For more memory consuming patterns this can cause the following error:
"re2/re2.cc:667: DFA out of memory: size xxxxx, bytemap range xx, list count xxxxx".

It would be nice if re2's max_mem option would be configurable via an Impala startup flag.
