Hi, That is quite great!
I think we can publish many functions what we want to do this year and attract more persons to join us. I list some interesting features here. Some of them are what I will do this year: 1. Distributed version, A distributed version is required. -- It can adopt a P2P architecture, which uses Gossip and phi-failure to sync basic information of the cluster. -- either a consist hashing algorithm or lookup table can be adopted for data partition. -- As for the replica, for each partition, we can use the Raft algorithm to elect a leader, and then the nodes that handle that data partition behave as a Master-Slave form. -- The data files are needed to re-organized to accelerate data transformation or replica repairing when scaling out the cluster or triggering the replica repairing. -- There are many other improvements that can be implemented for data replica. 2. Relational Schema supported. -- Currently, IoTDB uses a self-designed SQL, which is quite different with SQL in RDB. However, A standard SQL interface will attract more users and help users upgrade their existing database to IoTDB. -- Therefore, combining Apache Calcite with IoTDB may be the fast way to achieve it. 3. Time Series similarity search -- JiaYe Wu gave a KV-match index in dev@mail list. -- There are some other sub-sequence similarity search for time series, e.g., Paper: Matching Consecutive Subpatterns over Streaming Time Series. 4. More: Time series alignment, segmentation, prediction; Trigger for Streaming Calculation and Subscribe; etc..
