Achilles Custom Types

To support all Cassandra specific but powerfull features such as tunable consistency levels or counters, Achilles introduces custom Java types:

#### ConsistencyLevel It is an enum exposing all existing consistency levels in Cassandra:

• ANY
• ONE
• TWO
• THREE
• QUORUM
• EACH_QUORUM
• LOCAL_QUORUM
• ALL

Because Achilles supports both CQL & Thrift implementations, it has to define a custom enum for Consistency instead of re-using the enums provided by Hector or Java Driver Core libraries.

See Consistency Level for more details

#### Counter This type represents a **Cassandra** counter column. It exposes the following methods:

	public Long get();

	public Long get(ConsistencyLevel readLevel);

	public void incr();

	public void incr(ConsistencyLevel writeLevel);

	public void incr(Long increment);

	public void incr(Long increment, ConsistencyLevel writeLevel);

	public void decr();

	public void decr(ConsistencyLevel writeLevel);

	public void decr(Long decrement);

	public void decr(Long decrement, ConsistencyLevel writeLevel);
