v0.9.7 (Mar 07, 2018)

Overview of changes

• Enables high data density by turning multi-level indexing on by default. This allows efficient queries even where there is a lot of data per node.
• Core performance fixes to run better on lightweight (2 vCPU) machines
• Better handling of huge io spikes. The scenario is having many more requests from the clients than what the database cluster can handle.
• Tuning the Redis query layer performance
