Subject [Cassandra Wiki] Update of "API" by tuxracer69
Date Tue, 24 Nov 2009 09:06:49 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Cassandra Wiki" for change notification.

The "API" page has been changed by tuxracer69.

  === get_slice ===
    `list<ColumnOrSuperColumn> get_slice(keyspace, key, column_parent, predicate, consistency_level)`
  
- Get the group of columns contained by `column_parent` (either a !ColumnFamily name or a
!ColumnFamily/!SuperColumn name pair) specified by the given `predicate`.  If no matching
values are found, an empty list is returned.  Note that the number of columns returned is
limited to 100 as of [[http://issues.apache.org/jira/browse/CASSANDRA-262|0.4]].  This can
be modified without too much effort in Cassandra.thift by modifying the SliceRange struct.
 After doing so, rerun thrift by doing something like: ''thrift --gen (your language) -o /tmp
cassandra.thrift'' and then replace your languages official files (use locate to find them)
with the new ones in the /tmp directory.

  Returns a list of keys starting with `start`, ending with `finish` (both inclusive), and
at most `count` long.  The empty string ("") can be used as a sentinel value to get the first/last
existing key.  (The semantics are similar to the corresponding components of `SliceRange`.)
 This method is only allowed when using an order-preserving partitioner.
  
+ ''Note'': `get_key_range`'s design is kind of fundamentally broken, so we're deprecating
it in favor of `get_range_slice` starting in 0.5. In trunk (0.5beta) `get_range_slice` should
be used instead.
