Hi Vigya, > Should we also revert the default ReadAdvice.RANDOM setting for 10.2.1 > release?
I would prefer to not revert this in 10.2.1. The performance issue is not new in 10.2, it was introduced in a prior release. The focus of 10.2.1 is to address a couple of severe bugs are new in 10.2. Separately, we’re working on fixing the underlying issue in https://github.com/apache/lucene/issues/14422, which will hopefully make 10.3. -Chris. > On 24 Apr 2025, at 17:42, Vigya Sharma <vigya.w...@gmail.com> wrote: > > > There are multiple reports (1, 2) of performance regressions after this > change.
