# Merged in RocksDB 6.19.3, but not updated into MariaDB 10.6
Bug: https://github.com/facebook/rocksdb/issues/7035
Author: Otto Kekäläinen <otto@kekalainen.net>
Subject: Make RocksDB build reproducible

The RocksDB binary included a string with the build timestamp:
> rocksdb_build_git_date:@2021-05-23·16:04:38@

As this changes from build to build, it makes the builds unreproducible.
Simply removing it solves the issue.

This temporary fix can be removed when a proper fix already done in upstream
lands in MariaDB when the RocksDB submodule is updated to a newer release.
