Hi John,
Thanks a lot for the reply. I will test this out in my setup. Hope this will
help me. Just one question, if you are excluding HikariCP, then how the
Datasource will be created using ignite cluster's URL and credentials?

Ignite uses H2 syntax, so you could set H2 dialect:

Hello,
I don't think I clearly understand the issue you faced.
Please provide more details about the problem so that the community can
help you.
Could create a small reproducer project and share it on GitHub?
By the way, the log file from the server node will be helpful as well.
Thanks,

Hibernate is LGPL-licensed, so we stopped deploying there. To get artifacts
for 2.5 version that have LGPL dependencies, you need to build them from
the source [1] and deploy in your local repo.

Hi Denis,
Thanks for the detailed explanation ...
1. what if the query doesn't have any primary key or unique idbut still
have to load the entire table data in ignite for further join querying with
other caches
2. Data will change every time we hit select * from table in
Ignite transactions support this with REPEATABLE_READ isolation level.

I don’t quiet get how it getting a node for a key fits here (you’d need to know
some key then),
but ignite.affinity().mapNodeToKey() does this.

Well, you can use, for example, eviction policy:

Sriveena,
Read-through works as follows: when you do a cache.get(...), and a record
is not in the cache, then it goes to the configured CacheStore and requests
the value from it.
When the same key is read from cache next time, then call to the underlying
database doesn't happen, and caches value
thanks,
then in hibernate l2 cache, we do not provide the specific data to load
cache?(igniteCache.loadCache() )
but then, how many data will be in l2 cache, can I limit this space?

I have seen this document before.
However, I could not understand how datas are loading ignite cache(s)?
Can you explain what is going on this .java class?

Looks like you read a wrong documentation, for Hibernate L2 cache you don't
even need to implement CacheStoreAdapter - it's needed only for using 3rd
party db as a Cache Store. Here is the right documentation for using Ignite
as L2 Hibernate cache:
Even I am using apache ignite documentation or High Performance In-Memory
computing book,
I could not understand.
I have created simple cache with ignite (using postgresql) (implementing
CacheStoreAdapter vs...)
Also I have created simple hibernate project (gets data from database,
update vs...)
Hello Oleksandr,
The ignite-2.6 branch is already stabilized and frozen.
I hope the voting will be opened today!

Hi,
How does DataGrid readthrough works?
1. How does it auto synchronize the cache with database data?
2. Will it poll the underlying database?
3. Will it incrementally pull the data based on the key specified on the
cache?
4. Will the read through works if the cache

Hi Calvin,
It seems that the code is incomplete.
First, what are the Instant, DeltaMap types? What are the types stored in the
Map fields?
Second, do you have some code processing tool generating some code for you?

Hello
On one hand I have a cluster of Ignite Server nodes target to store a
partitioned cache.
On the other hand I have some "legacy" compute code running in its own JVM on
the same nodes as Ignite nodes.
I would like to integrate in this compute JVM's an Ignite client joining the
cluster
