Totally agree with the point that we should have some new architecture.

But before get started, we should know that the challenges really can’t be 
overcome in current architecture and IoTDB really needs the features in the 
challenge list. Each architecture has its pro and weakness. Actually what I 
worry about is when we spend a lot time on the new architecture but finally we 
just get very a few benefit.

I think we can follow the below steps to decide if we need a new architecture 
or not.


  1.  List the features expect to support.
  2.  Triage the features, filter out true requirements. (This can be done via 
vote.)
  3.  Can these true requirements be implemented in the current architecture?
  4.  If the answer in the 3 step is No. Then we really need a new architecture.

Architecture evolution is an eternal topic, we should know where we want to go 
in each step. It would be very great if you can share some ideas so that we 
could have some discussion.

How do you think?

What is the next architecture of IoTDB?

As we know,IoTDB cluster version is based on the standalone architecture and 
almost reused all the basic components of standalone version and just add a 
multi-raft protocol based on the thrift.

With the application spreading, the performance of the cluster version of IoTDB 
is changllaged for many aspects:
the num of nodes in cluster can support, the write and read performance in 
multi-replicas,
the linear ratio of read and write in cluster,
the efficiency and smartness of scheduler in cluster based on the dynamic 
workloads,
the joint query between time series data and relational data,
the federal cluster query across data centers, AZ and regions and the 
spatio-temporal data analysis in one DB etc…

So, I suggest we should make a blueprint for the next architecture of IoTDB and 
we can learn the advantage of the InfluxDB.
The InfluxDB has designed the next architecture named IOx and use Fusion as the 
next query engine and adopt parquet as the file format etc.

It's time to action, WDYT?
