Method Detail

key

public Object key()

Specified by:

key in interface CdcEvent

Returns:

Key for the changed entry.

value

public Object value()

Specified by:

value in interface CdcEvent

Returns:

Value for the changed entry or null in case of entry removal.

primary

public boolean primary()

Specified by:

primary in interface CdcEvent

Returns:

True if event fired on primary node for partition containing this entry.

partition

public int partition()

Ignite split dataset into smaller chunks to distribute them across the cluster. CdcConsumer implementations can use CdcEvent.partition() to split changes processing in the same way as it done for the cache.

Specified by:

partition in interface CdcEvent

Returns:

Partition number.

version

public CacheEntryVersion version()

Specified by:

version in interface CdcEvent

Returns:

Version of the entry.

cacheId

public int cacheId()

Specified by:

cacheId in interface CdcEvent

Returns:

Cache ID.

expireTime

public long expireTime()

Specified by:

expireTime in interface CdcEvent

Returns:

Time when entry will be removed from cache. If 0 then entry will be cached until removed.
