--------------------------------------
Summary: Access to several configuration tree in one configuration
change clojure is not thread-safe
Key: IGNITE-18516
URL: https://issues.apache.org/jira/browse/IGNITE-18516
Project: Ignite
Issue Type: Improvement
Reporter: Sergey Uttsel
h3. Motivation
In some cases in a change clojure on one configuration tree we need a
thread-safe access to another configuration tree.
For example:
{code:java}
zonesConfiguration.change(zonesChange ->
zonesChange.changeDistributionZones(zonesListChange -> {
tables = tablesConfiguration.tables();
boundTables = //find tables which are bound to the distribution zone;
if (boundTables.isEmpty())
zonesListChange.delete(zoneName);
})) {code}
Now there is no guarantee that list of boundTables is not changed before drop
zone.
h3. Definition of Done
It is possible to get thread-safe access to several configuration tree in one
configuration change clojure.
