Method Summary

Modifier and Type	Method and Description
long	getLastOffsetPersisted() LastOffsetPersisted is the encoded value for the Metadata message which is encoded in the ORDERER block metadata index for the case of the Kafka-based orderer.
long	getLastOriginalOffsetProcessed() LastOriginalOffsetProcessed is used to keep track of the newest offset processed if a message is re-validated and re-ordered.
long	getLastResubmittedConfigOffset() LastResubmittedConfigOffset is used to capture the newest offset of CONFIG kafka message, which is revalidated and resubmitted.

Method Detail

getLastOffsetPersisted

long getLastOffsetPersisted()

 LastOffsetPersisted is the encoded value for the Metadata message
 which is encoded in the ORDERER block metadata index for the case
 of the Kafka-based orderer.
 

int64 last_offset_persisted = 1 [json_name = "lastOffsetPersisted"];

Returns:

The lastOffsetPersisted.

getLastOriginalOffsetProcessed

long getLastOriginalOffsetProcessed()

 LastOriginalOffsetProcessed is used to keep track of the newest
 offset processed if a message is re-validated and re-ordered.
 This value is used to deduplicate re-submitted messages from
 multiple orderer so that we don't bother re-processing it again.
 

int64 last_original_offset_processed = 2 [json_name = "lastOriginalOffsetProcessed"];

Returns:

The lastOriginalOffsetProcessed.

getLastResubmittedConfigOffset

long getLastResubmittedConfigOffset()

 LastResubmittedConfigOffset is used to capture the newest offset of
 CONFIG kafka message, which is revalidated and resubmitted. By comparing
 this with LastOriginalOffsetProcessed, we could detemine whether there
 are still CONFIG messages that have been resubmitted but NOT processed
 yet. It's used as condition to block ingress messages, so we could reduce
 the overhead of repeatedly resubmitting messages as config seq keeps
 advancing.
 

int64 last_resubmitted_config_offset = 3 [json_name = "lastResubmittedConfigOffset"];

Returns:

The lastResubmittedConfigOffset.
