Re: HA & Missed Events with HyperLedger Fabric Events #fabric #fabric-sdk-node


The ChannelEventHub offers  the ability to be started or restarted with a 'startBlock' and/or 'endBlock'. The ChannelEventHub instance keeps the last block received number. The block number is also included in all event information provided to the callbacks of the application's registered listeners. When using chaincode events, it would be best to receive all events at one from a block of transactions in case the application goes down, this feature was added with fabric-client@1.4.2.
