> Introduce mechanism to fetch partition file via a p2p protocol
> --------------------------------------------------------------
>
> Key: IGNITE-9275
> URL: https://issues.apache.org/jira/browse/IGNITE-9275
> Project: Ignite
> Issue Type: Sub-task
> Reporter: Alexey Goncharuk
> Assignee: Maxim Muzafarov
> Priority: Major
> Fix For: 2.8
>
>
> As a first step to estimate how much faster the file-rebalancing may be, I
> suggest to implement a simple partition fetch procedure via the communication
> SPI extension:
> 1) Node A sends a partition fetch request to node B
> 2) Node B starts a checkpoint and creates a local copy of the partition. Note
> that during the partition copy there might be concurrent ongoing checkpoints,
> this must be handled properly
> 3) Node B establishes a new TCP connection on the TCP communication port
> (handshake and verification is assumed)
> 4) Node B calls transferFile (or native analogue, investigation needed) to
> send the partition file in the most effective way
> 5) Node A writes the file to a specified location on the local file system
> After this mechanics is implemented, we need to hack the rebalance code and
> use partition fetch logic instead of regular rebalance to measure
> 1) How much faster (or slower) the new approach performs
> 2) How it affects the concurrent transactions in the grid
