data inconsistency
I was looking at the architecture and I'm a bit puzzled by the fact that data inconsistency can occur and I'm wondering how I'm supposed to fix those.
Here's an example:
- client writes to relay
- relay writes to InfluxDB A and InfluxDB B
- InfluxDB A write is successful
- InfluxDB B write is not successful
- client got success message, because the write to A was first
So now I have 2 databases with different data. Although A has all the correct and complete data. Now imagine the same process as above again, but B gets the successful write and the client also gets the success message, because the write to B was first (and successful). In this case now both databases have incorrect and incomplete data.
Or am I missing something here?
@tessus You're right. I've noticed the same. Do you know of any alternatives?
Nope, but I guess that's the reason why they are selling the influxdb-cluster. They don't even want to solve this in the free relay code....
Please take a look on https://github.com/veepee-moc/influxdb-relay.
We tried to implement some useful features without conflicting with the paid version in InfluxDB (which is really great).
That's a lot of really interesting work @rockyluke, was there ever a PR to upstream it?
