[geomesa-users] Storm Ingest

[Nathan Mercer <nmercer@xxxxxxxxxxxx>]

Hi there,

 

I have tried implementing the Storm ingest example and I was successful. I was also able to apply it to my own data which is polygons stored in Shapefiles.

 

However, using Storm and Kafka you only get at least once guarantee which means you may ingest data more than once. And I have actually seen this happen with my implementation.

 

Apparently using Storm’s Trident you are able to get exactly once guarantee. But I have tried and tried and cannot get Trident working. None of the examples I have found online for Trident have a similar use case.

 

Has anybody been able to implement Trident for ingest? Does it even make sense?

 

Thanks,

 

Nathan Mercer
