--------------------------------------
Dmitry,
New tests added in this branch fail for me locally. Do they work for you? Do
you have link to TeamCity run (if you did not check TeamCity please do it)?
Thanks
> IgniteAtomicSequence: make following reservations in advance
> ------------------------------------------------------------
>
> Key: IGNITE-1678
> URL: https://issues.apache.org/jira/browse/IGNITE-1678
> Project: Ignite
> Issue Type: Improvement
> Components: data structures
> Affects Versions: ignite-1.4
> Reporter: Denis Magda
> Assignee: Dmitriy Govorukhin
> Fix For: 1.8
>
>
> In current implementation a new reservation is made when the current local
> sequence boundary is exceeded.
> In cases when there are many nodes that use the same atomic sequence there
> can be a situation when all the nodes start doing a new reservation at the
> same time. This can lead to performance drops.
> As a performance optimization it makes sense to start reserving new sequence
> slot in advance (in background), like when around 80% of current reservation
> has already been used. Probably we should add a special parameter to
> {{AtomicConfiguration}} that will manage such behavior.
