If you require rapid in-memory storage for your applications, you need look no further than Amazon ElastiCache for Redis. New and current users of this application will be happy to know that it now sports several useful features:
Sharded Cluster Support and Improved Console
Formerly, Amazon ElastiCache for Redis only allowed up to a cluster of just one primary node and maximum of 5 read replicas. This translates to 237 Gb of storage.
Now, ElastiCache can carry up to 15 shards, providing a total of 3.5 Tb of storage. This provides a great improvement in read/write performance and availability as each shard may also have up to 5 read replicas. This means up to 20M reads sand 4.5M writes each second.
Note that this needs a Redis client that is cluster-aware. ElastiCache will use the entire cluster as a unit for back up and restore. Additionally, AWS has updated the console to make it simpler to use.
Engine Update
ElastiCache has been updated to Regis engine 3.2. Some great features include:
- Enforced Write Consistency – A new WAIT command allows for It stops the caller until all standing write commands have been accepted at the primary node and the specified read replicas.
- SPOP with COUNT – You may now specify more than one element at a time to be removed and returned to a set.
- Bitfields – an efficient way to store small integers as bitmap and stored as a Redis string.
Geospatial Data
The update now lets you store geospatial data. New commands allow you to add a geospatial item, measure the distance between to items, get a Geohash string, give the positions of items given a key or radius of a location or an item.
