I am San. I am San. San I am.

That San-I-am! That San-I-am! I do not like that San-I-am!

Do you like Redis keys in RAM?

I do not like them San-I-am I do not like Redis keys in RAM.

Would you like them large* or small?

I would not like them large or small. I would not like them not at all. I do not like Redis keys in RAM. I do not like them San-I-am.

Would you like them as a String? Would you serialize everything?

I do not like them as a String. I do not like to serialize things. I do not like them large or small. I do not like them not at all. I do not like Redis keys in RAM. I do not like them San-I-am.

Would you like them in a Hash? Would you like a Hash as cache?

Not in a Hash. Not as a cache. Not as a String. No serialized, no anything. I do not want them large or small. I do not want them, not at all. I do not want Redis keys in RAM. I do not want them, San-I-am.

Would you want them as a List instead? Do you want to access tail, body and head?

Not as a List. Not as a Hash. Not as a String. Not as a cache. Small or large I will have naught. Goodbye San-I-am and thanks a lot.

Would you? Could you? As a Set? Get the difference! Store a union! Or just intersect...

I would not, could not, as a Set.

You may like them. You'll see for sure. You may like Sorted Sets by score?

I would not, could not by a score. No more Sets! I say no more! I do not like them as a List Stop this now - I do insist. I do not like them as String or Hash I do not like an in-memory database or cache. I do not want Redis keys in RAM. I do not want them, San-I-am.

You do not like them. So you say. http://try.redis.io! Try them! And you may. Try them and you may, I say.

San! If you will let me be, I will try them. You will see.

Say! I like Redis keys in RAM! I do! I like them, San-I-am! So I will have them as a String. And as a Hash, a List or anything. And as a Set - both unordered and an ordered one. Say! Data structures are so much FUN!

I do so like Redis keys in RAM Thank you! Grazie, San-I-am

• Keys in Redis can be up to 512MB and are binary safe. Simple string values can be up to 512MB and are binary safe as well. Other data structures can hold 2^32 elements, each up to 512MB.
