@JimRoepcke it's almost the only point with Dynamo systems, otherwise why to use such a system if the result is data loss?

@aphyr shopping cart? You want a Set performing union. Time series? You want a list performing smart head/tail merging, and so forth.

@aphyr so instead of dealign client-side with multiple returned vales, you pick the data structure depending on what you want.

@aphyr strategy for the different types. Like sets will do unions, and so forth. Maybe strings will just use clocks instead.

@aphyr an idea I explored time ago: take a dynamo system and put Redis-alike data structures on top of it. Then set a default merging...

IMHO the most shocking thing in the @aphyr series is to see how with wrong defaults Dynamo systems like Riak become fragile.

@aphyr good idea, worth to try. Still this should not be a problem at a first glance, clock jumps are much worse in general.

Salvatore Sanfilippo @antirez
@aphyr allow to take the time unaffected of the clock, but guaranteed to monotonically increase. This could be useful.

@aphyr what you can cause is to change the node timeout from the point of view of some Sentinel. Btw in Linux there are sys calls that

Salvatore Sanfilippo @antirez
@aphyr if you skew the clock continuously but very little every second, you can do that, but this will harm very little AFAIK (cont)

@romerorsp ciao Romero, basta la documentazione su redis.io. Potresti anche leggere qui: bit.ly/11MvP23

@aphyr thank you, not due, but appreciated. The only factual incorrect thing AFAIK is the TILT stuff, assuming I understood what you meant.

@aphyr I'm sure about that but the community not caring about high quality work is not a good sign.

It is incredible to me that none of the @aphyr blog posts hit the HN front page yesterday. Hope my post will help popularize his work.

@atl @aphyr I'm not defensive, I'm glad to him honestly.

Look at how @aphyr attacks many data stores, including Redis => aphyr.com That was a great work. I'm writing my reply right now

Seriously read this. Learn about data loss with Postgres, ACID & Two-phase commit. RT @aphyr: Call me maybe: Postgres aphyr.com/posts/282-call…
