@Deprecated
public interface PRDistributedAtomicSequence

AtomicSequence implementation for a distributed set up. The implementation depends on the type of underlying inmemory grid is used. Each implementation type(eg Ignite,HazelCast,Redis) should implement this interface. As of 7.3 only Ignite implements this interface.

long	getAtomicSequenceID(java.lang.String key, long lastSaveId) Deprecated. This method returns a unique sequence id in a distributed system This is thread-safe in the sense it will not generate the same id for two different thread.It will give unique sequence value each time it gets called.

Method Detail

isAtomicSequenceExist

boolean isAtomicSequenceExist(java.lang.String key)

Deprecated.

This method checks whether the sequence is already there in distributed memory

Parameters:

key -

Returns:

true or false

startAtomicSequence

void startAtomicSequence(java.lang.String key,
                         long startVal)

Deprecated.

This method create a new atomic sequence for the key

Parameters:

key - the key for which sequence will be generated

startVal - the start value from which the sequence will be generated

getAtomicSequenceID

long getAtomicSequenceID(java.lang.String key,
                         long lastSaveId)

Deprecated.

This method returns a unique sequence id in a distributed system This is thread-safe in the sense it will not generate the same id for two different thread.It will give unique sequence value each time it gets called.

Parameters:

key - the key for which sequence will be generated

lastSaveId - the start value from which the sequence will be generated

Returns:

long increamented atomic sequence value
