Simple key value store in Go

Key Value store in memory

Simple key value store in memory using a linked list to implement transactions and rollback.

The idea is to implement a simple version of a kv store to understand the concepts and how it can become more complex over time.

Usage

This example sets "test" to three different values using nested transactions.

Put signature is key, value, ttl.

		kvStore.Put("test", 1, nil)

		kvStore.Begin() // first T1

		kvStore.Put("test", 10, nil)

		kvStore.Begin() // nested T2

		kvStore.Put("test", 20, nil)

		kvStore.Commit() // end nested T2

		kvStore.Commit() // end first T1

		kvStore.Get("test") // value=10

In this example, "test" will be assigned to 1 -> 20 -> 10. 10 being the final value commited from the first transaction.

• KV store
• Transactions/Rollback
• TTL to entries. Expires on get
• Auto delete expired entries with a go routine
