[jira] [Commented] (FLINK-29795) The source.file.stream.io-fetch-size can not be set by table properties

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

    [ https://issues.apache.org/jira/browse/FLINK-29795?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17626018#comment-17626018 ] 

Aitozi commented on FLINK-29795:
--------------------------------

A reasonable fix to my mind, is to expose the original options in the properties to the format builder. So that it can fallback to the original options to get the \{{source.file.stream.io-fetch-size}}, then it will work I think.

cc [~martijnvisser] can you give me some suggestion on this ?

> The {{source.file.stream.io-fetch-size}} is used in the bulk format mode, but it is not exposed to the filesystem connector options. If I try to use it in the with property, it will fails with \{{Unsupported options}}. It can only be set by add it to the {{flink-conf.yaml}} now. It's not convenient and it should be scoped to the table's property.
