Ignite 2.0 transaction timeout not holding up

[Amit Pundir <am...@gmail.com>]

Hi,
I am using Ignite 2.0 and working with transactions with a 60 seconds
timeout. In the logs I see Ignite timeout exceptions with timeout less than
60 seconds in the exception message. 

The transaction concurrency has been set to PESSIMISTIC and the transaction
isolation level is REPEATABLE_READ.

Following is the grep'ed pattern from the logs which show timeouts with
different timeouts which are not 60 seconds. 

Could you please explain how the timeout works?

Re: Ignite 2.0 transaction timeout not holding up

Hi,

This timeout is for the whole transaction, but when for the transaction you
usually need to take locks on different nodes. So, when the transaction was
succeeded in acquiring locks on one node, it sends remaining timeout o next
node, to acquire locks on it. 

For example, when you see timeout=59980, it means, most probably, that
transaction acquired locks on node1 in 20ms and sent remaining
timeout(59980ms) to node2 and on node2 it didn't succeed in acquiring locks.
