------------------------------------------
Summary: Unpredictable nested listener invocation
Key: IGNITE-16361
URL: https://issues.apache.org/jira/browse/IGNITE-16361
Project: Ignite
Issue Type: Bug
Reporter: Vladislav Pyatkov
When you subscribe to any configuration property from another configuration
listener, you are forced to use the pattern:
{code}
configuration.property.listen((ctx) -> {
configuration.anotherProperty.listen((nestedCtx) -> {
if (ctx.storageRevision() == nestedCtx.storageRevision())
//Do nothing
else
//Some useful code.
})
})
{code}
Because an invocation with the same revision depends on traversal of the
configuration tree.
A reasonable solution to avoid this pattern and prevent using of the
unpredictable event is never notify nested listener about event that it was
subscribed.
