Cross cache transactional coherency

[Atri Sharma]

Folks,

I remember a conversation we had about cross cache transactional
coherency.  I remember Vladimir mentioning we have support for that from
1.0.0. Can anyone please point me to the required code Base?  I am trying
to hack a solution for the corruption issue when node is abruptly stopped.

Regards,

Atri

Hello Atri,

What corruption issue are you talking about? Is there a corresponding
ticket?

As for the transaction-related code, it has a lot of classes and the Base
would differ depending on what you want to look at. From the top of my
head, the main logic is concentrated in the following classes:

   - IgniteTxAdapter and it's inheritors contain all the state related to
   an ongoing transaction (including transaction on near, primary and backup
   nodes)
   - Grid*LockFuture classes contain logic related to entries locking in
   pessimistic mode
   - Grid*TxPrepareFuture classes contain logic related to the prepare step
   of a transaction
   - Grid*TxFinishFuture classes contain logic related to the finish step
   of a transaction
   - IgniteTxManager and IgniteTxHandler contain logic that wire up various
   transaction steps

Let me know if you have more specific questions, I will be happy to walk
you through the code.
