Use case:
We are using vertx-config to configure a database connection pool, we wanted to replace it with a new one when configuration is changed.
Retriever.configStream seems a perfect fit but it is not:
Setting a scan period of 30 seconds causes an inacceptable delay when verticle starts (30 seconds) because the first configuration is received after the scan period.
In order to solve it:
We are forced to Retriever.getConfig to get the configuration, and then open Retriever.configStream and discard the first read.
OR
Set a lower scanPeriod that introduces unwanted overhead to the system.
Introducing a firstScanPeriod or similar into ConfigRetrieverOptions will be greatly appreciated.
