== CQL ==
- The preferred interface to Cassandra 1.2 and 2.0 is CQL. There is a quick
introduction in GettingStarted and
[[http://www.datastax.com/documentation/cql/3.1/webhelp/index.html|full
documentation by DataStax]].
+ Cassandra offers a SQL-inspired interface called CQL. The primary difference
from SQL is the emphasis on denormalization (via Collections) over Joins.
- To use CQL effectively you should also understand

+ To use CQL effectively you should also understand the [DataModel].

- If you plan to write a [[ClientOptions|CQL client]], you should also read
about the communication
[[https://github.com/apache/cassandra/blob/cassandra-1.2/doc/native_protocol.spec|protocol
specification]]. Clients do not need to parse CQL, so you shouldn't need to
know the details of the [[http://cassandra.apache.org/doc/cql3/CQL.html|antlr
grammar]]

about the communication

== Thrift ==
- You can read about the legacy Thrift RPC API [[API10|here]].

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 JonathanEllis. http://wiki.apache.org/cassandra/API?action=diffrev1=52rev2=53 -- == Overview == - The Cassandra Thrift API changed between [[API03|0.3]], [[API04|0.4]], 0.5 and [[API06|0.6]]; this document explains the 0.5 version with annotations for the changes in 0.6. + The Cassandra Thrift API changed substantially after [[API03|0.3]], with minor, backwards-compatible changes for [[API04|0.4]], 0.5 and [[API06|0.6]]; this document explains the 0.5 version with annotations for the changes in 0.6. Cassandra's client API is built entirely on top of Thrift. It should be noted that these documents mention default values, but these are not generated in all of the languages that Thrift supports. Full examples of using Cassandra from Thrift, including setup boilerplate, are found on ThriftExamples. Higher-level clients are linked from ClientOptions.

'''WARNING:''' Some SQL/RDBMS terms are used in this documentation for analogy purposes. They should be thought of as just that; analogies. There are few similarities between how data is managed in a traditional RDBMS and Cassandra. Please see DataModel for more information.
