Subject [jira] [Updated] (CASSANDRA-2921) Split BufferedRandomAccessFile (BRAF) into Input and Output classes
Date Thu, 21 Jul 2011 12:53:58 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-2921?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Pavel Yaskevich updated CASSANDRA-2921:
---------------------------------------

    Attachment: CASSANDRA-2921-make-Writer-a-stream.patch

Patch changes a BRAF.Writer: instead of extending AbstractRandomAccessFile it expends AbstractDataOutput
(new class) and introduces mark() and resetAndTruncate(...) methods to satisfy scrub and CommitLong
requirements.

> Split BRAF into Input and Output classes to void complexity related to random I/O in
"write" mode that we don't need any more, see CASSANDRA-2879. And make implementation more
clean and reusable.
