Is AdminClient in package kafka-clients thread safe?

Question

I need to provide existention of kafka topic before producing events and default kafka topic autocreate is not adequate. I have desided to use AdminClient class but I am worried about concurency issues.
There is no information about thread safety AdminClient in documentation for Apache Kafka 2.2.x. Does somebody have any idea?

Answer 1

Yes, Apache Kafka's AdminClient is thread-safe, in every version of Kafka which it appears in. We will create a PR to update the documentation (I thought it was in the JavaDoc already, but it looks like not.)
