[jira] [Commented] (FLINK-19828) Allow loading multiple configuration files

["Robert Metzger (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/FLINK-19828?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17221492#comment-17221492 ] 

Robert Metzger commented on FLINK-19828:
----------------------------------------

I see two approaches:
a) consider all yaml files in a specified directory Flink configurations (instead of the current approach of looking for a specific file in the specified directory)
b) introduce a new configuration parameter to point to an additional configuration file

I prefer approach a). I believe we could sort the files by name, in case users want to introduce overwrites. It seems that one can mount a config map to a specific file in a directory: https://kubernetes.io/docs/tasks/configure-pod-container/configure-pod-configmap/#add-configmap-data-to-a-specific-path-in-the-volume

> This is a feature request from the mailing list: https://lists.apache.org/thread.html/r84ad3af6585ba8138d8bfa8d3d391dab9017aace52df8a757989be1e%40%3Cuser.flink.apache.org%3E
> For scenarios where you want to deploy Flink (for example on Kubernetes) with a set of common configuration keys (for example for the file system), and some deployment specific configuration keys (for example savepoint location), it would be helpful if Flink had a mechanism for loading multiple configuration files.
