What is Redis?
- In-memory data structure store
- Robust data types: strings, hashes, lists, sets, sorted sets
- Can use as cache, db, etc.
Why is Redis better than Memcached?
- Data types are very powerful
- Excellent support for atomic operations/transactions
- More robust caching features: pick from 8 eviction policies
- Exponentially better built in metrics/stats:
global info, global memory-specific info,
key-specific memory info - and more!
Redis sorted sets
- Non-repeating collection of strings,
each member with an integer score - Easy/efficient to add, remove, update elements
- Easy/efficient to get, remove multiple items by
score ranges, index ranges, etc.
