1. MVCC coordinator should not do anything when there is no MVCC
caches, actually it should not be active in such case. Basically, MVCC
coordinator is needed to have a consistent order between transactions.

Hi!
So it does not matter what node you restart ? it's always that one that
keeps the data ?
Are all 4 nodes part of the baseline topology ?
I pretty much have the same setup but with 3 nodes and have not had any
problems at all, not sure what it could be ?

Hi Guys - I have a four node cluster with native persistence enabled. Its a
partitioned cache and sync rebalance is enabled. When I restart the cluster
the first node that starts retain the data and all the other nodes data is
deleted and all the ignite data files are turned into 4096 byte files.
I'm trying to run the Spatial Query Example from the examples and getting the
following error:
javax.cache.CacheException: Failed to execute map query on remote node
[nodeId=2626e2d2-7c4c-40c4-a307-3cccf946eb68, errMsg=Failed to execute SQL
query. Data conversion error converting
public void CreateCache(string connectionString, string schema, string
table, Dictionary fields, string[] keys)
{
string query = String.Format("{0} {1}.{2}", "SELECT * FROM",
schema, table);
string cachename = CacheNameHash(connectionString, schema,
table);
Can you please attach full code as text? Can't run a screenshot :)

Yes, you can use IBinaryObject as a key. Yes, SQL will work too.

Sudhir, If I configure a cacheStore for a clientNode, then using 2.7.6 it becomes initialized twice, for both server and a client.Whereas I checked the same scenario against the master-branch and only a single cache store had created. Also, I have found the IGNITE-1903 that may fix the issue for

When using `dynamic` with Dapper, underlying objects are of type DapperRow,
which is also IDictionary,
which is easy to convert to BinaryObject. Here is a full example with
Dapper query:
var dapperQuery = conn.Query("SELECT * FROM Persons");
foreach (IDictionary row in dapperQuery)
{

Hello!
You can try using ignite.binary().ToBinary(obj).
However, in your case, it makes sense to avoid the intermediate object
stage directly and produce BinaryObjects from input data using builder.

I am reading the data using dapper from the database i am not sure how to

Hello!
You can use BinaryObjectBuilder:

However, each variation of its composition is stored in schema cache, which
means you should not have too many of those.
It is recommended to
I would like to store any time of object into cache as IBinaryobject, so i
can store cache stored in loosely bind with object. I am working with
Ignite .Net. Can someone please suggest something.
I need something like
MyObject obj = new MyObject();
obj.setFieldA("A");
obj.setFieldB(123);
Hello!
I think STARTED will be fired on all nodes, but only demander nodes will
spend time before STOPPED is sent.
So you should probably listen to events from all nodes, not just to local
ones.

I've ran your code under .NET and Java memory profilers.
In short, everything is working fine - nothing to worry about.

.NET managed memory usage is under 1Mb, unmanaged memory is much higher -
that is what Java part allocates.

Hi,
Are these events published on every node if rebalance is happening,
including the supplier node for the rebalance process?
My use case is something like this:
- when one node gets restarted, the first thing that is fired at startup is
the init container which would have an ignite client
