Thread-safety about dgraph4j

I have few tasks, which is a Runnable indeed, run simultaneously and they use the same DgraphClient from dgraph4j.

Is it thread-safe for DgraphClient?

Or how to use it properly in multi-threading environment?

Don’t worry too much . It’s thread-safe.
you can see

final ReentrantLock lrLck = new ReentrantLock();


in's source code .
