Description

We need to store the entity update events in some store. The search supported should return all events for a given entity id within some timerange.
Two choices are:
1. Existing graph db - We can create a vertex for every update with properties for entity id, timestamp, action and details. This will create disjoint vertices. The direct gremlin search is enough to retrieve all events for the entity.
Pros - We already have configurations for graph and utilities to store/get from graph
Cons - It will create extra data and doesn't fit the graph model

2. HBase - Store events with key = entity id + timestamp and columns for action and details. The table scan supports the required search
Pros - Fits the data model
Cons - We will need the configurations and code to read and write from hbase

In either case, we should expose an interface so that alternative implementations can be added
