------------------------------------
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.
