Summary: Clock skew managment
Key: IGNITE-18977
URL: https://issues.apache.org/jira/browse/IGNITE-18977
Project: Ignite
Issue Type: Epic
Reporter: Vladislav Pyatkov
*Motivation*
In a distributed system, all nodes have their own time view. A task to take
current time on a particular node have no guarantee that the timestamp is
achieved in all members in the topology. But our distributed algorithms
required to time synchronization until a specific accuracy.
The time interval on which all cluster clock can different is called a clock
skew. Cluster should support whatever any cluster node has the clock skew does
not bigger that it is defined for the topology.
