Scylla Java Driver
|
||
==================
|
||
|
||
Scylla Java Driver is forked from `DataStax Java Driver <https://github.com/datastax/java-driver>`_ with enhanced capabilities, taking advantage of Scylla's unique architecture.
|
||
|
||
The Scylla Java driver is shard aware and contains extensions for a ``tokenAwareHostPolicy``.
|
||
Using this policy, the driver can select a connection to a particular shard based on the shard’s token.
|
||
As a result, latency is significantly reduced because there is no need to pass data between the shards.
|
||
|
||
Use the Scylla Java driver for better compatibility and support for Scylla with Java-based applications.
|
||
|
||
Read the `documentation <https://java-driver.docs.scylladb.com/>`_ to get started or visit the `Github project <https://github.com/scylladb/java-driver>`_.
|
||
|
||
The driver architecture is based on layers. At the bottom lies the driver core.
|
||
This core handles everything related to the connections to a Scylla cluster (for example, connection pool, discovering new nodes, etc.) and exposes a simple, relatively low-level API on top of which higher-level layers can be built.
|
||
|
||
The Scylla Java Driver is a drop-in replacement for the DataStax Java Driver.
|
||
As such, no code changes are needed to use this driver.

Using CDC with Java
|
||
-------------------
|
||
|
||
When writing applications, you can now use our `Java Library <https://github.com/scylladb/scylla-cdc-java>`_ to simplify writing applications that read from Scylla CDC.
