What'm I missing? AWS it's either just part of the default quotas or it's a simple automated form 000
Reposted by James HendersonAndras Gerlits @omniledger.io · 03/02/2025Based on the SQL-spec, why do we need to use locks at all (in an MVCC DB), when we do REPEATABLE READ or READ COMMITTED? Why can't we just expose changes at commit with a future timestamp and read with a past timestamp? Is this like a "vestigial organ" thing? 121
