----------------------------------
Resolution: Fixed
> Optimize amount of data stored in discovery history
> ---------------------------------------------------
>
> Key: IGNITE-4154
> URL: https://issues.apache.org/jira/browse/IGNITE-4154
> Project: Ignite
> Issue Type: Task
> Components: general
> Reporter: Semen Boikov
> Assignee: Semen Boikov
> Fix For: 1.8
>
>
> Currently on large clusters with lots of caches amount of data stored in tcp
> discovery history can grow too much.
> What can be improved:
> - TcpDiscoveryNodeAddedMessage.oldNodesDiscoData contains per-node discovery
> data. For cache component essentially this is list of configured caches, and
> for joined node at the time when 'collectDiscoveryData' is called this list
> should be the same on all nodes, so it can be stored once instead of per-node
> map
> - even after message is discarded it is still stored in PendingMessages
> collection, looks like it can be safely removed after discarding
> - now system property IGNITE_DISCOVERY_HISTORY_SIZE controls both size of
> events needed for client reconnects and number of topology snapshots stored
> in GridDiscoveryManager, need have two properies
> - for clients TcpDiscoveryNodeAddFinishedMessage.clientDiscoData can be
> initialized only when message is sent to joining client
