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 JonHermes. http://wiki.apache.org/cassandra/API?action=diff&rev1=68&rev2=69 -------------------------------------------------- Remove data from the row specified by `key` at the granularity specified by `column_path`, and the given `timestamp`. Note that all the values in `column_path` besides `column_path.column_family` are truly optional: you can remove the entire row by just specifying the !ColumnFamily, or you can remove a !SuperColumn or a single Column by specifying those levels too. Note that the `timestamp` is needed, so that if the commands are replayed in a different order on different nodes, the same result is produced. + === describe_cluster_name === + ''Requires Cassandra 0.6'' + + . `string describe_cluster_name()` + + Gets the name of the cluster. + + === describe_version === + ''Requires Cassandra 0.6'' + + . `string describe_version()` + + Gets the Thrift API version. + + === describe_ring === + ''Requires Cassandra 0.6'' + + . `list<TokenRange> describe_ring(string keyspace)` + + Gets the token ring; a map of ranges to host addresses. Represented as a set of `TokenRange` instead of a map from range to list of endpoints, because you can't use Thrift structs as map keys: https://issues.apache.org/jira/browse/THRIFT-162 for the same reason, we can't return a set here, even though order is neither important nor predictable. + + === describe_keyspace === + ''Requires Cassandra 0.7'' + + . `KsDef describe_keyspace(string keyspace)` + + Gets information about the specified keyspace. + === describe_keyspaces === - ''Requires Cassandra 0.6'' + ''Requires Cassandra 0.7'' - . `set<string> describe_keyspaces()` + . `list<KsDef> describe_keyspaces()` + Gets a list of all the keyspaces configured for the cluster.
