Subject [jira] [Commented] (OAK-4582) Split Segment in a read-only and a read-write implementations
Date Wed, 20 Jul 2016 20:33:20 GMT

    [ https://issues.apache.org/jira/browse/OAK-4582?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15386572#comment-15386572

Michael Dürig commented on OAK-4582:

Interesting approach. I have yet to look at your branch, but IIUC this is about separating
the read and write concerns of segments. I think this is a good idea and it should allow us
to further decouple our code base later on.

> {{Segment}} is central to the working of the Segment Store, but it currently serves two
> # It is a temporary storage location for the currently written segment, waiting to be
full and flushed to disk.
> # It is a way to parse serialzed segments read from disk.
> To distinguish these two use cases, I suggest to promote {{Segment}} to the status of
interface, and to create two different implementations for a read-only and a read-write segments.
