Alexander Lapin updated IGNITE-23874:
-------------------------------------
Description:
It's required to implelement following logic on partition start.
{code:java}
1. chain.link(nodeName) sends stateRequest(chain.link(current).next().cfgIndex,
chain.link(nodeName)next.nodes() - chain.link(nodeName).next.next.nodes()
2. stateRequestHandling
return nodeAlive || hasUserInputs
3.majorityOf(stateRequestHandlingResponse) processing
if (true) {
thisNodeOrPrevLinkHasUserInputs = true;
do not start. (erase local state (?))
}
else {
if (hasUserInputs()) {
start
} else {
do not start. (erase local state (?))
}
} {code}
[~alapin] will provide more detailed description today.
