----------------------------------------
Summary: When PDS is enabled and IGNITE_BINARY_SORT_OBJECT_FIELDS
property is set and IgniteCache#put is called a node hangs
Key: IGNITE-7085
URL: https://issues.apache.org/jira/browse/IGNITE-7085
Project: Ignite
Issue Type: Bug
Components: binary
Affects Versions: 2.1
Reporter: Alexandr Fedotov
Assignee: Alexandr Fedotov
Fix For: 2.4
When PDS is enabled and IGNITE_BINARY_SORT_OBJECT_FIELDS property is set and
IgniteCache#put is called a node hangs.
The root cause is that when IGNITE_BINARY_SORT_OBJECT_FIELDS flag is enabled
BinaryMetadata#fields field is stored as TreeMap, but because
BinaryUtils#WRAP_TREES is
set by default, that leads to BinaryMetadata#fields being wrapped into
BinaryTreeMap.
When an update for BinaryMetadata is initiated it ends up in a discovery thread
from where
a metadata update for BinaryTreeMap is initiated. Since this update should be
processed by the same discovery thread, that results in a deadlock.
