Parallelize inserts into accountPatchReviewDb in schema 127 On large sites, parallelizing inserts helps reduce the migration time of this schema significantly. Default number of migration threads is equal to number of CPUs or can be manually configured through system property 'schema127_threadcount'. This change reduced the time from ~600s to ~ 300s on a postgres based Gerrit site(on a machine with 24 CPUs) with ~25M records in table account_patch_reviews and DB type as postgres for accountPatchReviewDb. Around 30% improvement also was seen when DB type is H2 for accountPatchReviewDb. Updates to schema 127 impact the upgrade of Gerrit to version 2.13.

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.
