It seems that this delayExportExecutor is a global delay exposed component. I don't think we can delete this field.

Since ServiceConfig exists, we can export the service at runtime, so we can't determine if delayExportExecutor will still be used. In addition, maintaining an object in memory does not have a big impact.

Each ServerConfig instance holds its own delayExportExecutor and delayExportExecutor only used for delay exporting,I feel it is unnecessary to use it.

agree with @carryxyh , all ServiceConfig holds the same delayExportExecutor

My fault, I didn't notice that it was static.

can we call delayExportExecutor.shutdown() method after the delay task add work queue?

Don't think so.
If I want to export the service at runtime(use ServiceConfig), turning off delayExportExecutor will cause problems.
