How to reuse tcp connection

How to reuse tcp connection

I am choosing a time series database with excellent performance, and I have chosen influxdb as my first choice.But I encountered a situation
I use the java sdk client to write data to influxdb2, but I find that every time I write a piece of data, there will be a tcp connection in the state of time_wait, which is too strange
Why does this happen and how can I avoid it, or achieve tcp connection multiplexing
influxdb version is 2.6.1 and use default config

java demo:

sdk version: influxdb-client-java:6.7.0

happened

Start with the Java demo in the issue and the influxdb-client-java 6.7.0 behavior against InfluxDB 2.6.1 using the default configuration. Investigate whether each write creates a TCP connection and determine the documented or expected way to reuse connections; done when the cause and a reproducible resolution are established.
