Details of the IRedisClient API implemented by the ServiceStack.Redis client

Introduction

This is a friendly, more descriptive API implemented by the ServiceStack.Redis client that provides access to key values as strings (or collection of strings for Redis lists and sets).

Use this API if you just need to access values as strings or you want to have control over your own text serialization format.

Generally, if you only have basic persistence needs I would recommend developing against the above common data access API as it is easier for other persistence providers to implement and increases the likely hood that your existing library can be reused as-is to have your POCO types persist against other data stores i.e. against an RDBMS with OrmLite, etc.
