Hi,
IoTDB only supports stand-alone version now. We plan to develop distributed
version in next two months.
We initially decided to use the master-slave architecture. The master node is
responsible for processing read and write requests, and the slave node, which
is a copy of master no
Hi XuYi,
I like the idea but I'm unsure if I like the master / slave approach.
We often deal with "Shopfloor" Scenarios where the setup for the Database is
basically "MultiMaster", because we need to sync data one the one hand, but if
a system goes down, everything else should keep working.
Woul
yep, I think the cluster is in P2P mode when they startup. Then a leader
election algorithm will change the cluster into the M/S mode (RAFT
algorithm is qualified). If the master is down, a new master can be elected
and lead the cluster.
By the way, we need to consider the cost of keeping strong c
Hi,
this is a very interesting (and important) question.
I think we should really consider what we can skip (from an application
perspective) and what to keep.
Perhaps a Token Ring architecture like Cassandra uses could also be a good fit,
if we hash on the device id or something.
At least in th
I, on the other hand, would be very interested in the strong consistency option.
(Very cool discussion!)

Hi Felix,
could you elaborate a bit on your use cases?
I am a bit unsure about the consistency, so it would be interesting to hear
where you see the important points.
Thanks
nk I’d generally agree on A in CAP too. But is it going to be eventual
consistency? Or it could split brain and lose data?
