--------------------------------------
Summary: Apache IoTDB: integration with gRPC
Key: COMDEV-464
URL: https://issues.apache.org/jira/browse/COMDEV-464
Project: Community Development
Issue Type: New Feature
Components: GSoC/Mentoring ideas
Reporter: Xiangdong Huang
*Background:*
Apache IoTDB uses Thrift as its RPC layer. However, there are some voices in
the community: do we need to support gPRC?
We noticed:
* thrift has to apply memory for each RPC call (get data from the network into
a byte array, and then convert the bytes to objects), and it is hard to control
the whole memory cost for large RPC.
* thrift connection may be broken when there are too many concurrent
connections.
* thrift does not support stream mode
So, we'd like to know whether gRPC is better.
*Tasks:*
* implement IoTDB's RPC layer using gRPC.
** including the sync/async mode
** sub-tasks: the C++, c#, python API wrappers are also desired.
* have a performance test
** throughput, memory cost and jitter, etc..
* write a report to compare them
*References:*
iotdb's current thrift RPC specification:
# [https://github.com/apache/iotdb/tree/master/thrift]
# there are some on-going thrift apis: thrift-datanode, thrift-confignode,
thrift-cluster, thrift-sync
