Hi Val,
Thanks. You're not missing anything and we have been using Ignite
persistence for years.
Among the reasons we want to switch to in-memory only is how easily we seem
to get corrupt nodes. I mentioned in the first email. We haven't had a
situation where upgrading corrupts more than 1 of our 3
Hi Zhenya,
We use the IA C# client (deployed in a.Net Core implementation using
containers on AWS EKS) so this makes it hard for us to run Java closures
from the C# client, which is why a client interface capability would be
useful!
Thanks,
Raymond.

You can call it through compute api [1], i suppose.

Hi Zhenya,
1. We currently use AWS EFS for primary storage, with provisioned IOPS to
provide sufficient IO. Our Ignite cluster currently tops out at ~10% usage
(with at least 5 nodes writing to it, including WAL and WAL archive), so we
are not saturating the EFS interface. We use the default page
Hi, you can use BinaryObject API without defining any classes:
ignite.binary().builder("ANY_STRING_HERE");
builder.setField("id", 1);
builder.setField("name", "John");

HI
We dont need a model / pojo class or value object defined for a table while
creating a table and we can still insert data thru SQL and read the data
thru SQL API as well as Java KV or binary objects
However, if we want to insert data thru Java API by using binary object or
KV (put cache), we do

This is not difficult to do with command line Java tooling if you can
easily access the server running the node. However, access to those nodes
may not be simple (especially in prod
As another detail, we have the WriteThrottlingEnabled property left at its
default value of 'false', so I would not ordinarily expect throttling,
correct?

Hi Courtney,
Thanks for your feedback!
To cut the story short, Ignite implements page memory architecture. All
data is split into fixed-sized pages and any page can reside either both in
memory and on disk or on disk only. Since the in-memory layer and
persistence layer are natively integrated -
Hi Ilya,
Regarding the throttling question, I have not yet looked at thread dumps -
the observed behaviour has been seen in production metrics and logging.
What would you expect a thread dump to show in this case?
Given my description of the sizes of the data regions and the numbers of
pages bein
I know this was over the holiday so bumping. Can anyone provide any
pointers on where to start looking or anything else mentioned in the
previous email?
Thanks

Hi igniters!
I have created a table using JDBC. And I would like to fill it with data
using data streamer. But after that I can't execute sql query and get data.
After some experimentation, it turned out that SQL select does not return
the data put in the table using the cache API.

Maybe it is related to https://issues.apache.org/jira/browse/IGNITE-13863?
If it is not, please provide thread dumps from nodes in the cluster.

I have just checked the example, and I can definitely see something:

Hello!
Have you also tried adding wrap_value=false parameter to your DDL
statement? OtherwiseIgnite will assume you have a one-field POJO as a value.

I believe I told you what to do specifically. You can also just append all
of your SSL-related settings to JDBC connection string, like you will do
with sqlline tool.
