cannot run them in parallel because they need to take an rdonly instance offline to perform the comparison. NOTE: This example does not actually run this command. NOTE: SplitDiff can be used to split transactions that give you distributed atomic guarantees. However, choosing this option increases the write cost by approximately 50%. Single shard transactions continue to remain ACID, just like MySQL supports is one case that is not addressed by Vitess. The current recommen- dation is to absorb the latency cost of long-distance round-trips for writes. If the data distribution allows, you still have the option

Code Auditing Phase 2. Code-Assisted Penetration Testing Miscellaneous Issues VIT-01-001 MySQL: Comparison of Auth Token allows timing Attacks (Info) VIT-01-002 MySQL: Timing attacks due to plain-text while a vulnerability is present, an exploit might not always be possible. VIT-01-001 MySQL: Comparison of Auth Token allows timing Attacks (Info) One of the discovered issues allows an attacker to performed by xoring the tested bit with sha1(salt + sha1(sha1(pw)). By exploiting the timing-unsafe comparison, an attacker would be able to retrieve sha1(pw), which is sufficient for authenticating to the
