[jira] [Commented] (HDDS-8635) Automatically select createKey and createStreamKey in Ozone FileSystem

["Tsz-wo Sze (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HDDS-8635?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17723497#comment-17723497 ] 

Tsz-wo Sze commented on HDDS-8635:
----------------------------------

We may buffer user data in OzoneFSOutputStream.
 # If user closes the file and the file size is within a certain limit, use the createKey API to send the data.
 -- We may use PutSmallFile to further optimize it in the future.
 # If user keeps writing and the bytes written is larger than the limit, use createStreamKey.

> When streaming is enabled (OZONE_FS_DATASTREAM_ENABLED), currently it always uses the createStreamKey API for creating a file.  However, streaming is inefficient when creating small files.  It should automatically select createKey API when the file size is small.
