Impala 2.5.0
Description
The fix for IMPALA-2648/IMPALA-2664 introduced a conservative limitation on the maximum serialized size of incremental stats. As a result, some users with very large tables experienced regressions when upgrading because incremental stats did not work anymore.
We should consider making the limit configurable, or even better fix the design to allow a much higher limit.
Dimitris, assigning to you for triage/consideration.
