Is the client builders for AWS s3 or any other service side effecting?

[VladKopanievITV]

Would the code like this AmazonS3ClientBuilder.standard().build() execute any IO, open connections or change global mutable state?

[debora-ito]

The instance of S3 client returned by build() is immutable.
It will create the connection pool, but not open connections at startup. Connections will be created lazily.

Nice, thanks for confirming, Debora!
