The Cassandra Driver wraps the complexity of accessing Cassandra services in an easy-to-integrate, pure Java JDBC Driver. Applications then access Cassandra through the Cassandra Driver with simple Transact-SQL.

The CData JDBC Driver for Apache Cassandra hides the complexity of accessing data and provides additional powerful security features, smart caching, batching, socket management, and more.

Cassandra Application Integration

The Cassandra Driver has the same JDBC architecture as the JDBC drivers for MySQL and OLEDB, including Connection, Statement and ResultSet objects. Because of this you can now access Cassandra data in an easy, familiar way. You can use the Cassandra Driver through popular IDEs (Eclipse, IntelliJ, NetBeans, etc.), in code through familiar classes, and in data controls available through Swing, Eclipse SWT Widgets, etc.

For example:

Connection conn = 
	DriverManager.getConnection("jdbc:cassandra:user=myuseraccount;password=mypassword;");

boolean ret = stat.execute("SELECT * FROM CQL Queries");
ResultSet rs=stat.getResultSet();
while(rs.next()){
  for(int i=1;i<=rs.getMetaData().getColumnCount();i++)
  {
    System.out.println(rs.getMetaData().getColumnName(i) +"="+rs.getString(i));
  }
}


More Than Read-Only: Full Update/CRUD Support

Cassandra Driver goes beyond read-only functionality to deliver full support for Create, Read Update, and Delete operations (CRUD). Your end-users can interact with the data presented by the Cassandra Driver as easily as interacting with a database table.

Connection conn = 
	DriverManager.getConnection("jdbc:cassandra:user=myuseraccount;password=mypassword;");
	
String query = "UPDATE CQL Queries SET Where= ..."; 

PreparedStatement pstmt = conn.prepareStatement(query);
pstmt.setString(1, "Location");
pstmt.setString(2, "UID");
pstmt.execute();
int count=pstmt.getUpdateCount();

Connect to Apache Cassandra Data from Code

The Cassandra Driver offers a standard SQL Server or MySQL interface to data, with read/write (CRUD) support. This powerful remoting features makes it easy to connect your applications with Apache Cassandra data regardless of your solution architecture.

Use one of the standard client libraries for accessing SQL/MySQL from .NET, Java, PHP, Python, Ruby, Objective-C, etc. to start your integration with Cassandra.


JDBC Driver Performance

With traditional approaches to remote access, performance bottlenecks can spell disaster for applications. Regardless if an application is created for internal use, a commercial project, web, or mobile application, slow performance can rapidly lead to project failure. Accessing data from any remote source has the potential to create these problems. Common issues include:

  1. Network Connections - Slow network connections and latency issues are common in mobile applications.
  2. Service Delays - Delays due to service interruptions, resulting in server hardware or software updates.
  3. Large Data - Intentional or unintentional requests for large amounts of data.
  4. Disconnects - Complete loss of network connectivity.

The CData JDBC Driver for Apache Cassandra solves these issues by supporting powerful smart caching technology that can greatly improve the performance and dramatically reduce application bottlenecks.

Smart Caching

Smart caching is a configurable option that works by storing queried data into a local database. Enabling smart caching creates a persistent local cache database that contains a replica of data retrieved from the remote source. The cache database is small, lightweight, blazing-fast, and it can be shared by multiple connections as persistent storage.

Caching with our JDBC Drivers is highly configurable, including options for:

  • Auto Cache - Maintain an automatic local cache of data on all requests. The provider will automatically load data into the cache database each time you execute a SELECT query. Each row returned by the query will be inserted or updated as necessary into the corresponding table in the cache database.
  • Explicit Cache - Cache only on demand. Developers decide exactly what data gets stored in the cache and when it is updated. Explicit caching provides full control over the cache contents by using explicit execution of CACHE statements.
  • No Cache - All requests access only live data and no local cache file is created.

This powerful caching functionality increases application performance and allows applications to disconnect and continue limited functioning without writing code for additional local storage and/or data serialization/deserialization.

More information about JDBC Driver caching and best caching practices is available in the included help files.
