Hi Anil,
Is there one-to-one relation between person and address/company? If yes,
then you just load three rows from different tables and create an object
based on fetch information. You can load data via IgniteDataStreamer or
within your implementation of CacheStore:

otherwise, it would lead to data problem. and i am using vertx-ignite.
please share if there are other cluster manager better than vertx ?
Thanks for you help.

HI,
are there any recommendations (other than affinity) for complex queries
like below.
SELECT DISTINCT b.id, b.filename, a1.name
FROM a a1
JOIN b
ON b.id = a1.id
LEFT JOIN (select a.id, max(rank) latest from a group by a.id) a2
ON a2.id = a1.id
Thanks.
Can someone point me to the ignite xml configuration for network
segmentation ?
i see IgniteConfiguration property names for network segmentation and
setting methods are different :)
Thanks

Thanks Val.
But the default STOP option not looks correct. There is always chance of
rejoining of cluster.
But if ignite cache is stopped because of segmentation, rejoin has no
meaning.
Creating different clusters still fine as long as cache is not stopped in
case of network segmentation.

Hi Val,
I agree with you on "separate clusters running". but ignite is stopped.
Separate clusters has no meaning. agree?
Thanks

Hi Val,
I have created a complex query and looks good in terms of query plan. But
query execution time is very high.
query -
SELECT
P.serialnumber,
iP.count,
cnt.itemnumber,
cnt.status,
cnt.enddate
FROM Product P
left JOIN ( SELECT serialnumber, COUNT(*) AS count FR
Hi,
is it mandatory to use key of a cache as part of the affinity key of
another cache ?
i see all examples on github are using the same.
In my scenario, key of a cache (person) cannot be part of affinity key of
another cache (person details). how can we achieve affinity?
Thanks.
