Approximate Nearest Neighbour (ANN) Vector search via Storage-Attached Indexes
As a developer or data scientist looking to carry out advanced analytics,
I want to leverage ANN Vector search across the data in my Cassandra instance, 
so that I can develop machine learning applications and capabilities. 
In addition, the following up stream CEP is of interest to me : https://cwiki.apache.org/confluence/display/CASSANDRA/CEP-30%3A+Approximate+Nearest+Neighbor%28ANN%29+Vector+Search+via+Storage-Attached+Indexes
