Oct 11, To fix this issue, newer versions of CockroachDB now clear the transaction ID for overlapping timestamp cache entries with identical timestamps. It's important to test and tune your hardware setup before deploying to production. Cheaper gp2 volumes can be used instead, if your performance needs are less demanding. CockroachDB is well suited for applications that require reliable, available, and correct data regardless of scale. PostgreSQL is also supported by a devoted and experienced community and can be extended with strong third party support. You can run it on your local computer, a single server, a corporate development cluster, or a private or public cloud. Individual keys within CockroachDB are stored by a single Raft cluster: updates to them are linearizable because they go through Raft consensus.
CockroachDB FAQ - What is CockroachDB? How does it work? Since CockroachDB is inspired by Spanner, does it require atomic clocks to synchronize time?

Below is a simulation highlighting how multi-regional data can self-organize with Geo-partitioning. This will likely be difficult to productionize, as it would take up a lot of space on disk to store latencies for all query fingerprints in an active database, but it's an interesting idea that a few people have been talking about so I'll make a quick prototype to see whether or not it's useful.
Version: v While it did not break the build it seems to break something for developers using their local compiler MacOS? Bankadapted from the Galera snapshot isolation testverifies that CockroachDB conserves the total sum of values in a table, while transferring units between various rows.
