Migrate from Hazelcast to KiviDB

Hazelcast is an in-memory data grid: Java objects in distributed maps, queues and topics, reached through Hazelcast's own client protocol or by running a member inside your application. KiviDB is a key-value server that speaks RESP, the Redis protocol. Nothing copies across as it is: you choose a KiviDB type for each Hazelcast structure, copy the data with a small client program, and change the code that used the Hazelcast API. This guide covers all three.
