Awesome read and still quite impressed by Aerospike.
I currently work for a company that uses Aerospike quite heavily. In the past couple weeks, we have begun to notice data inconsistencies in our counters. We are seeing fluctuations in the data, despite having no decrement operations. We have the enterprise edition of Aerospike, allowing us to be in constant contact with their support team and developers. A couple weeks later, and we still have no idea why this is hap…
Can you add any detail to this anecdote? It's interesting and important, but detail might help steer others appropriately. What kind of inconsistency? What kind of fluctuation?
The first I found when debugging an issue. I noticed the counters going up, dip down, then continuing up. Rinse repeat. (e.g., 158 -> 160 -> 158 -> 170 -> 175 -> 173 -> 180)
The second I found was when trying to debugging the previous issue. I noticed the counters were essentially cycling. (e.g., 158 -> 160 -> 170 -> 158 -> 160 -> 170). This just repeated for the duration we watched the counters (approximately five minutes).
Please note that I used small numbers here. The counters I was monitoring were in the hundred millions, and I saw decrements in average between 2-3k.

Yikes. What made you choose Aerospike in the first place?
I'm sure many of you know, this leads to quite a few issues.
Earlier quoted context omitted.

I'm current working in AdTech. We are using counters to keep track of a lot of things that are important to us (e.g., reasons for not bidding on a given campaign, money spent within a given transaction, number of bid requests we get by exchange, etc). I personally have found two different, yet very similar, data fluctuations. The first I found when debugging an issue. I noticed the counters going up, dip down, then c…
How big is this cluster? Are you writing and reading to the entire cluster, or do you have certain nodes that you write to and others that you read from?
Is there any reason he's never tried to analyze a "classic" RDBMS like Oracle or SQL Server? I have to imagine they'd clobber a lot of this hipster technology.

Here is a bit of an index page: https://aphyr.com/tags/jepsen . It doesn't appear that he has. And yes, I would guess that they would indeed clobber those written there.
