Subject [jira] [Commented] (CASSANDRA-2231) Add CompositeType comparer to the comparers provided in org.apache.cassandra.db.marshal
Date Wed, 01 Jun 2011 15:08:48 GMT

donal zang commented on CASSANDRA-2231:
---------------------------------------

Hi,
forgive me if the question is naive.
I'm using the release 0.7(http://svn.apache.org/repos/asf/cassandra/tags/cassandra-0.7.6-2/)
and  when I apply the patch , it can't find the file TypeParser.java :
$patch -p1 < 0001-Add-compositeType-and-DynamicCompositeType_0.7.patch
patching file src/java/org/apache/cassandra/db/marshal/AbstractCompositeType.java
patching file src/java/org/apache/cassandra/db/marshal/CompositeType.java
patching file src/java/org/apache/cassandra/db/marshal/DynamicCompositeType.java
can't find file to patch at input line 694
Perhaps you used the wrong -p or --strip option?
The text leading up to this was:
--------------------------
|diff --git a/src/java/org/apache/cassandra/db/marshal/TypeParser.java b/src/java/org/apache/cassandra/db/marshal/TypeParser.java
|index a3fabc5..0b21042 100644
|--- a/src/java/org/apache/cassandra/db/marshal/TypeParser.java
|+++ b/src/java/org/apache/cassandra/db/marshal/TypeParser.java
--------------------------
File to patch: 

So, am I missing something?

> CompositeType is a custom comparer that makes it possible to create comparable composite
values out of the basic types that Cassandra currently supports, such as Long, UUID, etc.
 This is very useful in both the creation of custom inverted indexes using columns in a skinny
row, where each column name is a composite value, and also when using Cassandra's built-in
secondary index support, where it can be used to encode the values in the columns that Cassandra
indexes.  One scenario for the usage of these is documented here: http://www.anuff.com/2010/07/secondary-indexes-in-cassandra.html.
