Suppose a sensor ticks whenever a car is passed on a road, and you want to count occurrences. Addn. Like the Bloom filter, the main things we want to do are create one, add things to it, and check if they exist. This is a container command for latency diagnostics commands. Like TTL this command returns the remaining time to live of a key that has an expire set, with the sole difference that TTL returns the amount of remaining time in seconds while PTTL returns it in milliseconds. The command is always propagated in the replication link and the Append Only File as a HSET operation, so that differences in the underlying floating point math implementation will not be sources of inconsistency. addnx; cf. 1:6379> TS.
