Summary: Consolidate ClientManagers in Datanodes for unified
management
Key: IOTDB-5312
URL: https://issues.apache.org/jira/browse/IOTDB-5312
Project: Apache IoTDB
Issue Type: Improvement
Reporter: Xinyu Tan
Assignee: Xinyu Tan
The ClientManager of Datanodes is divided into different modules. On the one
hand, thrift client reuse rate is not high. On the other hand, under the
current thriftServer thread model of BIO, thread explosion may occur. The PR
will mainly consolidate ClientManagers in Datanodes and do some necessary
reconstruction
* Consolidate ClientManagers in Datanodes for unified management
* Move some clientFactory from DataNodeClientPoolFactory to ClientPoolFactory
* Add thrift related parameters to CommonConfig so that they can be retrieved
by ClientPoolFactory
* By introducing ThriftClientFactory, the BaseClientFactory is not bound to
thrift, so that the RatisClientFactory does not depend on thrift related
parameters in the future
* Enhance clientManager's handling of null, adding necessary judgments and
removing unwanted ones
* Adds invalidation logic for exceptions that occur when an asynchronous client
fails
