Hello Chris,
IGFS was developed with the thinking that it would be a solution for Hadoop
acceleration. However, it was discovered in practice that the performance
benefits it gives are insignificant for production deployments. For
instance, based on my experience IGFS combined with Hadoop Accelera
Hello,
Are you using IGFS as a standalone file system or as a way to accelerate
Hadoop? If for the latter then I would suggest considering an alternate
solution that is proved to be efficient for production deployment and
Hadoop offloading:

Hello,
In short, Ignite persistence primary advantages are:
- Enables multi-tiered storage across RAM and disk - 100% of data
persisted to disk ("warm" and "cold" data sets) while "hot" data always
stays in RAM. You lay out the data the way you need. Applications just run
queries and
Hello,
I'm looking to get memory (heap/off heap) consumed by my cache across
the cluster. If possible also per node. What is the best way of doing this.
Thanks,

Hi,
I am in a project where we are building a new database with strong
normalisation requirements - very much like a relational data warehouse. We
source the data from HDFS. And the maintenance team requires the data
movement to be implemented through SQL APIs.
Main Question: Would it be a viabl
Stéphane,
Could you provide the code, that results in this exception?
Do you try to insert the tuple as a single field via SQL? There is no such
primitive as a tuple in SQL, so you should probably split timestamp into
datetime and nanoseconds columns and store them separately as two different
colu
Hello,
I am wondering what sort of File Properties can be set in ignite using the
IgniteFileSystem.create(IgfsPath path, int bufSize, boolean overwrite, int
replication, long, blockSize, Map props) method.
I am using the default storage. It's not obvious to me in the code what
choices I have for

Do you mean that the client node with the data streamer doesn't join the
cluster? Or the node joins, but just doesn't receive any data from Kafka?

Hello!
Would this question be better suited to the contributor's distro? For one
thing, I have a couple of patches I would like to submit if IGFS has a
future.
Thank you.

Mike,
First of all, it's recommended to have a separate cache per table to avoid
storing of objects of different types in the same cache.
Continuous query receives all updates on the cache regardless of their
type. Local listener is invoked when new events happen. Existing records
can be processe
Clay,
If you want to store plain strings without any schema or markup, then use
varchar.
But if you plan to store POJOs, then binary objects should certainly be
used instead of varchar. Binary types contain meta information, improving
type safety of stored data.
Binary objects don't apply any com
Hi,
is there any plan to add support of SQL API in C++ thin client?
If yes, is it known in which version should it be supported?
Thanks!

I'm trying to save some raw binary data into Apache Ignite using thin Python
client and the process is very slow (actually it looks like it depends on
the size of the data).
For my simple test case I've started locally Ignite with single node
(version 2.7.0 without any specific configuration):

We are using Ignite 2.7 as a 4-server-node session cluster but recent weeks
we found some Ignite WebSessionFilter client threads eating up CPU usage
after days of running.
The GC is running smoothly.
How to address the root cause?
Is it a Ignite 2.x known issue with StripedExecutor?
