Provide configuration to paginate index queries with increasing size A 'pageSizeMultiplier' config entry is added to allow paginating index queries with increasing size. Default multiplier is set to 1 to keep the current pagination unchanged. 'maxPageSize' has also been added to limit the maximum results a repeated index query can request. Increasing page sizes can help with performance of queries such as [1] where the visibility is being queried for an account that cannot see most/all changes. On a site with 1M abandoned changes, queries like [1] finish in: 45.1 mins with paginationType=OFFSET and pageSizeMultipler=1 8.5 mins with paginationType=OFFSET and pageSizeMultipler=10 9.1 mins with paginationType=SEARCH_AFTER and pageSizeMultipler=1 8.2 mins with paginationType=SEARCH_AFTER and pageSizeMultipler=10 This change also acts as a stepping stone for the next one in the series where no-limit will be updated to paginate without any regressions. [1] gerrit query 'status:abandoned visibleto:guest' Release-Notes: Index searches can now paginate with increasing size Change-Id: Iee014d1391c15d7ef31770b4fca538122944eb6b
Gerrit is a code review and project management tool for Git based projects.
Gerrit makes reviews easier by showing changes in a side-by-side display, and allowing inline comments to be added by any reviewer.
Gerrit simplifies Git based project maintainership by permitting any authorized user to submit changes to the master Git repository, rather than requiring all approved changes to be merged in by hand by the project maintainer.
For information about how to install and use Gerrit, refer to the documentation.
Our canonical Git repository is located on googlesource.com. There is a mirror of the repository on Github.
Please report bugs on the issue tracker.
Gerrit is the work of hundreds of contributors. We appreciate your help!
Please read the contribution guidelines.
Note that we do not accept Pull Requests via the Github mirror.
The Developer Mailing list is repo-discuss on Google Groups.
Gerrit is provided under the Apache License 2.0.
