 **Important notes**
 
 - "full", means it has been optimized for both storage, and query operations.
 - "storage" means does not support optimization for queries, for large queries, this can have detrimental performance implication, as the apistack will need to iterate a large number of data.
 - Hazelcast require a custom build / deployment with the JavaCommons JAR file to support the required functionality
 - MySQL connection / db seems to support only up to 16 digits of accuracy
+- Requires read-after-write consistency, for expected behaviour, use w=majority&readConcernLevel=linearizable
