Alexey Scherbakov resolved IGNITE-22130.
----------------------------------------
Resolution: Fixed
> Fix retry logic for transactions
> --------------------------------
>
> Key: IGNITE-22130
> URL: https://issues.apache.org/jira/browse/IGNITE-22130
> Project: Ignite
> Issue Type: Improvement
> Reporter: Alexey Scherbakov
> Assignee: Alexey Scherbakov
> Priority: Major
> Labels: ignite-3
> Fix For: 3.0
>
> Time Spent: 2.5h
> Remaining Estimate: 0h
>
> Recently (IGNITE-21540) retries was introduced for transactions, both
> explicit and implicit.
> But the current implementation has flaws:
> # In embedded mode retries cause recursion (because the future is completed
> on the same thread), which can lead to stack overflow.
> # Retries are executed without delay in a loop, which might not give enough
> time for conflicting lock release, making retries almost useless.
> # Read operations are not retried but need to.
> # Data streamer operations are not retried but need to.
> To fix 1 and 2 I suggest to submit a response for retryable operation (if
> retry is required) to another thread to avoid recursion and introduce retry
> delay for retriable operations, preferrably with exponential back-off.
> Fix for 3 and 4 is obvious.
