Re: remote ignite server and L4(for loadbalacing) with java thin client

[kay <go...@gmail.com>]

Hello, I'm waiting for reply :)

I use java thin clien.

1. Can I use java thin client with 'Affinity Collocation'?
2. Is there any information about 'partition awareness' ? like, example
link.
3. Ignite thin client on startup select's random server to connect available
address.
This selection(connect to server node) is not going to be change before
server node is shut down?? or my application restart?
I mean if I have only one Ignite thin client Object( like singleton ) in my
application.
Is it only use one server node?


Thank you so much

Hello,

Currently, there is no way to add a new address without the client restart.
But there is a feature under development [1], perhaps, it will be useful
for your case.

Hello, Thank you so much!.

I have 1 more question.

I use IgniteClient API in my application.(singleton)
when i start my application I regist IgniteClient bean using SpringFramework
and declare ClientConfiguration  address like  

ClientConfiguration cfg = new
ClientConfiguration().setAddresses("34.1.21.122:12800",
"34.1.21.122:12800");

 Is there any way to add new ClientConfiguration address without my
application restart??
I'm considering using L4 between my application and ignite server node.. but
also L4 should be restart.

Is it possible to auto scale out java client thin level??

Hello,

1. Yes, the same way as with the thick client.
2. Here [1] is a short description of partition awareness future for .NET
thin client (but this description also relevant to other thin clients,
including java thin client). Here [2] is a low-level description (mostly
for Apache Ignite developers).
3. Yes, java thin client stay connected with the selected server node until
connection lost (network segmented, server node is shut down, etc.). Only
after losing connection, client tries to connect to the next server node
