Implementing Routing Strategy in KV Store on top of MySQL

• Implementing put, get, del, ttl operations all in sync.
  

• We create 2 tables and 2 connections simulating DB Partitions kv_store_shard1 and kv_store_shard2.
  NOTE: Naming of the tables wrong - should be partition not shard

• Run the set_db.sql file to create DB, and partitions. Run: mysql -u root -p < <path to set_db.sql>

• Implementing Routing technique, using a consistent hashing mechanism.

hash := sha256.Sum256([]byte(key))
idx := int(hash[0]) % shardCount

• Randomly get, put, del values.
