you're kind of missing the problem here - who should be the master? The choice of master is a static configuration set by the user. Redis itself has no failover or promotion ability. There's an additional thing called Sentine

data loss due to a broken replica-repair strategy. That's the thing: Redis has no read repair strategy. Redis has a "be an exact copy of your master" strategy. It's not a secret. It's the exact design. The comp

Quick semantic cleanup: Redis has two types of persistence: snapshot persistence (RDB) and journal persistence (AOF). It sounds like they tried only snapshot ("copy the world") persistence, found it to increase latency, then turn

In the case described, there is no promotion logic. The replicas will try to reconnect to their original master forever unless something else (like Sentinel) redirects them in an actual failover/promotion setup. So, the master had data

That's kinda an obtuse version of a middlebrow dismissal. You're positioning yourself as "of course— I knew better all along! Bow before my foresight!" In other anecdotal evidence, I've been using Redis as a persi

Well, companies also use ejabberd, but that doesn't make ejabberd a valid piece of software either. Then there's the massive problem of "everyone" using MongoDB and we know how much pain _that_ sucker causes. Playing po

The code is just strange. To support Redis, it has a 2,500 line Redis adapter. It has special cases for each Redis command because it doesn't extract key position information from Redis directly. Plus, despite the name and where it&#

Picking out the three points: not highly available, not consistent, and not partition tolerant. [reverting to non-standard, dummy definitions below just to explicitly define some things] Redis Cluster is available as long as (50% + 1) of

async != an incorrect system. Very correct! Most of the mysql problems derive from it being statement replication and not log shipping. A proper postgres replication setup will be less prone to having data inconstancies.

This doesn't describe a lot of use cases. Do you have any idea how many people run master/slave mysql? That's async and will definitely give you data drift over time. There's an entire suite of Percona tools to det

Excellent point except for the math mistake! A 10% rent increase in $1000/month rent make the new rent $1100/month, so your total additional cost is $1200/year, not $100/year! Then , on top of all that, your salary inc

For all we know, making an intractable problem tractable is the necessary step to make AI a reality. But, we know that's not a necessary step. We have computer vision systems working essentially the same way our brains perceive imag

I think there's two viewpoints. There's "outside in" when the media calls things like Siri "AI" then there's the scifi AI perspective where we want talking starships. Siri++ doesn't get us closer to

Would the Semantic Web (e.g. vertical knowledge graphs) qualify as AI? Anything resembling OpenCog or Freebase isn't AI—it's just a database with clever retrieval through traversal hierarchies. The world does need better ways to

In fact, there's no clear way to even define AI, It's easy to define, but the term has been stolen by people wanting more media attention for less work. AI is just "what we are" without all the squishy parts. AI (&quo
