-----------------------------------
Hi all, I would like to take this issue:D
> Implement built-in builder class for the Session/SessionPool class
> ------------------------------------------------------------------
>
> Key: IOTDB-1463
> URL: https://issues.apache.org/jira/browse/IOTDB-1463
> Project: Apache IoTDB
> Issue Type: Improvement
> Components: Client/Java
> Reporter: Xinyu Tan
> Priority: Major
> Labels: easy-fix
> Fix For: master branch
>
>
> Currently, the number of parameters that the Session/SessionPool class can be
> configured by the user is increasing, leading to an increasing number of
> confusing constructors. Therefore, we can consider introducing the builder
> class SessionBuilder/SessionPoolBuilder in the Session/SessionPool class, so
> that users can focus only on the parameters they need to focus on. For the
> builder design pattern, you can refer to [this
> .|https://zhuanlan.zhihu.com/p/58093669]
> {code:java}
> // default
> Session session = new SessionBuilder().build()
> SessionPool sessionpool = new SessionPoolBuilder().build()
> // set remote ip
> Session session = new SessionBuilder().setHost("localhost").build()
> SessionPool sessionpool = new
> SessionPoolBuilder().setHost("localhost").build()
> // set remote ip
> // close cache leader
> Session session = new
> SessionBuilder().setHost("localhost").setEnableCacheLeader(false).build()
> SessionPool sessionpool = new
> SessionPoolBuilder().setHost("localhost").setEnableCacheLeader(false).build()
> {code}
> `
> Of course, in order to ensure compatibility, the previous session
> construction interface can not be removed, we need to recommend that users
> gradually migrate to the builder creation method, so as to gain greater
> convenience
