Subject [jira] [Updated] (CASSANDRA-8230) LongToken no longer needs to use a boxed Long
Date Fri, 31 Oct 2014 15:22:33 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-8230?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Branimir Lambov updated CASSANDRA-8230:
---------------------------------------
    Attachment: 8230-2.1.patch

I went a little further with this, also changing some other features of the token code that
did not make much sense. The attached patch applies after 8171, comparison is viewable [here|https://github.com/blambov/cassandra/compare/blambov:8171-2.1-generics...8230-2.1-token-impr].

{panel}
Small reorganization and simplification of the Token hierarchy:
* LongToken inherits directly from Token and gets a primitive long token
field, improving efficiency.
* BytesToken no longer inherits from AbstractToken as it was not making
use of any of its functionality.
* AbstractToken becomes applicable to Comparable tokens only, allowing
more shared functionality to be moved there.
* AbstractByteOrderedPartitioner is simplified as it is only used with
byte[] tokens.

> After CASSANDRA-8171 a token reference field is no longer a requirement for tokens. This
permits LongTokens to include a primitive long field, which should noticeably improve the
space and time efficiency of the Murmur3Partitioner tokens.
