Summary: Allow warming up data region before a node has joined Key: IGNITE-10152 URL: https://issues.apache.org/jira/browse/IGNITE-10152 Project: Ignite Issue Type: New Feature Reporter: Stanislav Lukyanov After a node with existing PDS joins the cluster its performance will be low for a while - until it loads all data into RAM. This is a feature of Ignite - cold restart - that allows nodes to start as fast as possible. However, it would be good to also allow "hot restart" - a way to preload as much data into RAM as needed before the node has joined. Then the node will not slow the cluster down during its warm-up. There are several recent improvements with similar goals: - IGNITE-8873 added methods to preload data of a specific partition - IGNITE-7196 and IGNITE-9420 moved data recovery to before node joins the cluster Combining the above approaches we could have allow a user to trigger synchronous preloading right after the data recovery but before discovery starts up. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
