I think what he means is that no files are being created.. We are doing some
tests with Ignite and we don't see any use of the cache, even when we load
more keys than fit in physical memory.

I'm just wondering if I am deploying Ignite to Hardware let's say with 128GB
RAM on each node.. Is it best to have just one ignite process run on the
machine and use the entire machine.. Or should I run multiple ignite
processes on the same machine?

We were directly Manipulating the Cache.Entry and it was
reflecting directly in the H2 Indexes.. Not sure if it's desired behavior or
not.. But a definite Gotcha
To fix this we just call VALUE = ingintecache.get(KEY) to retrieve the value
rather than getting it directly from the entry (VALUE =
I think this is a bug..
I have meetings most of today.. I will definitely get you a code Sample..
copyOnRead is set to true.
Will work around it and try to get you code examples later today..
Basically this is easy to re-produce though, all you have to do is do a
query and pull an object out of
To expand on this is seems that if I use a QueryCursor to return the values
and I manipulate them, the H2 Database's value and indexes are changed.. But
If I pull the value out of the cache..
So changing values returned by a QueryCursor will cause the H2 index to be
changed?

Working with an ignite cache and I leave the H2 Debug window open while I'm
working.. So what I have noticed happening is that when I change values in
an object, this is IMMEDIATELY changed in the H2 Database window, even if I
start a transaction.. Should this happen only when I get and put a value

I found this article..

I can't find the Grid object int Apache Ignite.. Is this even possible now?
I would be great for each node to save out it's cache to LevelDb and read it
in upon startup

I am building an ORM/Graph Database on top of Ignite.. Just wanted to know if
it is best practice on machines to close a cache after using it. Is it safe
to keep a map of handles to a bunch of classes? Or should we close or bound
the Ignite Caches?

I am trying to set up our Ignite Grids so that they don't see each other..
For example if I have 2 grids of different names, they see each other.. And
this is causing a problem because the have different classes loaded.
This is in a development environment where there are different developers

It could be 100's or even 1000's of objects..
Say we have Object A is related to Object B we need a way of expressing the
association so that we can navigate from one to the other.
it's a many to many association type idea.. If we co-locate the association
cache with the source, then we cannot na
We have an object that contain an array of long[] values
What I am trying to do is to find all of the objects that contain a value in
that array.. Kind of trying to simulate edges in a graph database.. We can
achieve this goal via link tables and SQL
Alternatively I was thinking of indexing the o
