Hi Vinoth,
Thanks for reply. I want some more help from you.
We are designing a product where we have to process online incoming request
from some frontend and after processing this request we have to send it to
intranet and we also want to get response intranet.
We call it request-process-respo

Thank you very much Taylor for prompt reply :-)
In short, no. Not today.
Storm's acking mechanism is largely stateless (one long can track an entire
tuple tree),which is one of the reasons it is so efficient.
But the acking mechanism is also based on Storms core primitives, so it is
entirely possible.
There is a JIRA for adding additional m
Apart from the autopurge options, also set the number of transactions after
which a snapshot is taken (snapCount). This number should be set depending
on the rate of updates to zookeeper.

Do Trident variants of kafka spouts do something similar?
Thanks

Hi guys,
For a Storm topology, if a tuple failed to be processed (either timed out
or fail method got called on the tuple explicitly), I understand that fail
method of the spout will be called with the tuple message id. Other than
that, can Storm provide any info as to the last bolt that had proce
I'll do a couple tests, but for the most part it should just work on OSX, etc.
(Storm releases are built on OSX).
What version of maven are you using? Have you tried with the latest version?

Hi guys,
got exactly the same results trying to build storm (exactly the commands as
mentioned).
Tried on: Xubuntu 12.04.4 and OS X Mavericks 10.9.2.
Would be great to know what's the cause of this issue :-/
Is there a way to tell how many batches per second are being processed by
my topology?
Thanks

Will have a look at those. Thanks for your suggestions!

I believe you should be using a Trident Kafka spout variant if you're
building a Trident topology, not the plain Storm KafkaSpout one.

You have to configure ZooKeeper to automatically purge old logs.
ZooKeeper's logs tend to grow very quickly in size, so you should enable
the autopurge option in zoo.cfg or they will eat your available disk
space. I suggest you read ZooKeeper's Installation And Maintainance Guide.

The aggregations are done by Storm. persistentAggregate provides only a
means to access the datastore to get the current aggregate for the

Is this the case ? Or will the Persistent Aggregate use the external
datastore in order to do the aggregations ?

if you want to see the result you can try programming your bolt to save
results emitted from the spout/bolt on a file .
as example :
