You might have consistency problems if you have: multiple datastores in multiple datacenters, without distributed transactions, and with the ability to alternately execute out of each datacenter; syncing protocols that can fail or sync stale data; distributed clients that cache data and then write old back to the central store; a NoSQL database that doesn’t have transactions between updates of multiple related key-value records; application level integrity checks; client driven optimistic locking.
This blog is called myNoSQL and it is written by me, Alex Popescu, a software architect with a passion for open source and communities.
It records my readings, learnings, and opinions on NoSQL databases, polyglot persistence, and distributed systems -- subjects that I'm passionate about.
The opinions expressed here are my own, and no other party necessarily agrees with them.
If you feel I'm biased, I probably am.
