[geomesa-users] Is there available an asynchronous or lazy Java CQL driv

[Benjamin Weaver <Benjamin.Weaver@xxxxxxxxxxxxxxxxxx>]

Hi all,

We are returning large resultsets from Accumulo (1.7.2) while running Geomesa 1.2.1. Our system frequently runs slow and locks up. We believe our problems owe to our use, in our queries, of the non-lazy FeatureIterator. The problem seems to be that our query returns our entire resultset, loads that set into the FeatureIterator, before we traverse that FeatureIterator, converting features into protobuf and returning to the client.

Our NATS server does not appear to be the bottleneck. We have noticed via metrics that the query itself takes the substantial portion of time.

Do we have available an asynchronous or lazy Geomesa driver or iterator enabling return of large results sets as they are returned from Accumulo? Is such asynchronous/lazy functionality available in Geomesa 1.2.1 or any newer version of Geomesa?

Any perspective is greatly appreciated!

Ben
