Redis - Lists
Redis Lists are simply psts of strings, sorted by insertion order. You can add elements in Redis psts in the head or the tail of the pst.
Maximum length of a pst is 232 - 1 elements (4294967295, more than 4 bilpon of elements per pst).
Example
redis 127.0.0.1:6379> LPUSH tutorials redis (integer) 1 redis 127.0.0.1:6379> LPUSH tutorials mongodb (integer) 2 redis 127.0.0.1:6379> LPUSH tutorials mysql (integer) 3 redis 127.0.0.1:6379> LRANGE tutorials 0 10 1) "mysql" 2) "mongodb" 3) "redis"
In the above example, three values are inserted in Redis pst named ‘tutorials’ by the command LPUSH.
