Thank you for your reply.
I did as you suggested in the mail.
but on accessing the url I get an error "Sorry, remote connections
('webAllowOthers') are disabled on this server.".
How do I pass "webAllowOthers" parameter to h2 database through ignite?
Thanks

Is it possible to have the Ignite Queue data be persisted via some sort of
Store? I've looked at the docs and can't seem to find any info on how queues
(and Sets for that matter) relate to the CacheStore and read/write
through/behind - how does this work? Essentially, I'd like for the data in
the q
Hi Roger,
You can use Ignite-Cassandra integration module. In case you need to load
specific portion of you Cassandra dataset into Ignite you can use
*loadCache(...)* method of Ignite cache API, providing it appropriate CQL
query.

Hi,
I saw this remark on the mailing list from vkulichenko:

I want to develop my own CacheStore implementation to a data store.
The data store will have a "contact point" or client running on each Ignite

I have got the answer, but will write more info about our use-case, since it
might be useful for someone in the future.
We need to return value, but it will take some time (seconds, minutes) to
process those requests. The IgniteServices gives us decoupling from
knowledge about co
Hi,
Possibly, H2 planned use different indices for these queries.
Try to use HINTS [1] if it is impossible to make H2 use proper index
without breaking other queries.

IgniteSpringBean encapsulates lifecycle management and in general provides

Yes,I had study the document many times.
But the document is too simple.
I still have two question:

particular setting is perfect to me.
2.what is the URL if I open browser?
