Hi All,
Is it possible to use stream receivers with JDBC connections (with
streaming set to on)? If yes, can you point me to an example?
thanks.
Hi,
Looks like you are loading the ML plugin twice (see below)
Can you try w/out the plugin config first.
Just copy the ignite-ml module to the libs folder or
follow these instructions:

If that works, put in your

Hi,
Tableau desktop can indeed connect to Ignite via the odbc driver.
1. Install the driver:
https://apacheignite-sql.readme.io/docs/odbc-driver#installing-odbc-driver
2. create the appropriate dsn via windows Odbc
3. use's Tableau's connect via ODBC feature. (Keep in mind the Ignite
Your best choice is to write your own exporter/use sqlline/other tool to get
the data from Ignite.
Ignite's db files are in a proprietary format that can't be used w/other
tools.

Honestly near cache for the thin client is a must for me. Implementing
this is a huge performance gain.

Folks, thanks for sharing ideas.
Let me find a designer who can turn the ideas into pictures. Then we can
compare and adjust.

Hello!
I think it needs not be present on server, but I recommend testing that :)

Hi Alex,
Thanks for your response. I want to export the data into a SQL db file
which can be then loaded with any standard SQL viewer. CSV would be
difficult for me as the data stored in these tables is huge. Just to give
some context, one of the services running on this cluster would pump one
Yes, it is a node information.
heap = onheap, so, just use "a" as onheap memory used.

I suggest checking the logs from the cluster nodes - there should be
messages that node is using this IP and that it was bound to 8080 port.
Also, it makes sense to check the connection between these machines, there
is a chance that you have a firewall or ports are blocked.

Question is still open:
In case of using TreeMap with Comparator provided to constructor, should
this comparator be present on server node, or it is just applied on client
side?

Hello!

Hello!
Is it possible that you are not closing your JDBC result sets (or
corresponding Ignite QueryCursor)?
It's actually strange. The query in question seem rather bulky. It's not
expected that it is sufficiently fast for you.

My confusion is, where to fire the task, does Ignite will help launch this
task when startup the ignite instance?
I have tried, but not found any logs output.
If ignite cannot help launch, only load the class into memory, then where to

For example, method 'compute' has last argument as 'T arg' which is passed
to task.
Please see

Alex,
I've recently implemented .NET Native Near Cache [1].
It is a very similar concept, because caching is performed on platform side.
We had requests for this from different users for quite some time.
Users were implementing this on their own with Continuous Queries.

Hello,
I don't think that near cache for thin client on Ignite level it's a
good idea.
Expiration is not the only case here. For thick clients near caches are
transactionally consistent. For thin clients such a guarantee never can be
provided.
Near cache for thin clients will be either too heavy

Can I understand the task deployment like this:

will not trigger that, task will only trigger by outside the ignite client

In this case, outside programmer only need to know the taskName, and call

"use the REST API shared by Dmtriy to trigger the task."
How to do that? can you share more details, now I have the task deployed to
