Is this real-time or batch?
If batch this is perfect for MapReduce or Spark.
If real-time then you should use Spark or Storm Trident.

Allocate RAM for workers that are launched on supervisor nodes. Workers do
the heavy lifting and are the component that actually run your topology.

I am using the storm for an academic experiment and have a question. Where
it is necessary to allocate more memory (RAM) for Zookeeper, Nimbus or the
supervisors? Why?
H,
I’ve implemented a topology consisting of a spout, processing bolt and a sink
bolt pushing data back to Kafka.
By examining the logs, I’ve seen that for all of the 12 partitions the
totalSpoutLag and totalLatestTimeOffset remain constant (i.e. approximately at
830K), although tuples are
My use case is that I have a json which contains an array. I need to split
that array into multiple jsons and do some computations on them. After
that, results from each json has to be used in further calculation
altogether and come up with the final result.
*Cheers!*

What's your use case?
The complexities can be manage d as long as your tuple branching is
reasonable I.e. 1 tuple creates several other tuples and you need to sync
results between them.

You're right. For that I have to manage the queue and all those
complexities of timeout. If Storm is not the right place to do this then
what else?

The correct way is to perform time window aggregation using bucketing.
Use the timestamp on your event computed from.various stages and send it to
a single bolt where the aggregation happens. You only emit from this bolt
once you receive results from both parts.
It's like creating a barrier or
But how would that solve the syncing problem?

Hi Chen,
Could you try running your topology with Storm 1.0.2 in local mode? Since
it's in local mode you can easily try it out.
Thanks,

My topology runs well in cluster mode but throws exceptions when it is
submitted in local mode. It makes the debug work so tough.
The error is:
4842 [main] INFO o.a.s.l.ThriftAccessLogger - Request ID: 1 access from:
principal: operation: submitTopology

Hi
I am thinking of doing the following.
Spout subscribed to Kafka and get JSONs. Spout emits the JSONs as
individual tuples.
Bolt-A has subscribed to the spout. Bolt-A creates multiple JSONs from a
json and emits them as multiple streams.
Bolt-B receives these streams and do the computation
17 matches
