Redis Command: HGET

Get the value of a single field of a hash. This is the simplest command for getting the value from a hash, but only one field can be fetched from the hash. HMGET supports multiple fields, and HGETALL returns all data of a hash. So you can use these if these commands serve your purpose.

Redis Command: LTRIM

Trim a Redis list, and remove items from the list from one or both end(s). We provide a starting and ending index for the trim and the items outside that window are removed. If all items are removed while trimming, then the list is deleted. Indexes are Zero(0) based.
