Commands that won't be implemented

This is just the current status, and may change in the future. If you have ideas on how to implement any of them feel free to tell us about it.

redis	why it doesn't make sense to emulate
debug	This command is intended to aid in debugging redis
dump	Doesn't make sense to implement the internal data format used by RDB
hello	THe protocols this command is switching between (RESP2, RESP3, Redis 6) aren't in use
latency	ioredis-mock isn't operating over the network so there is no latency to monitor
memory	It's unlikely this can be emulated in a JS environment
migrate	This command actually executes a DUMP + DEL on the source instance, and a RESTORE in the target. Since DUMP and RESTORE won't be implemented it includes MIGRATE.
module	It's unlikely that we'll be able to run Redis Modules in a JS VM
pfdebug	This command is intended to aid in debugging redis
restore	The RDB specific format used for restores would be a massive undertaking to implement with very little gain.
slowlog	Useful when you're on redis, not so much when on ioredis-mock
