Running out of memory? Learn how Redis Enterprise enables large dataset analysis with the highest throughput and lowest latency while reducing costs over 75%! 

A new article on the DataStax blog provides an interesting look at why the vector clocks conflict resolution strategy isn't used in DynamoDB or Apache Cassandra, even though it was used in the early Amazon Dynamo database, which was the ancestor of both Cassandra and DynamoDB.

The article is a good breakdown of vector clocks, and it's a good resource for learning a little more about newer databases in general.  You should also check out the comments, since there is some contention about how the author describes certain aspects.
