Description Gustavo Fernandes 2015-03-23 19:47:36 UTC

Description of problem:

A new node joining a cluster with large number of entries can experience severe delays when using SYNC indexing (the default)


Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. Create a node (library or server node) with indexing on, insert 1 million entries in a replicated cache, index storage can be RAM
2. Add a new node to the cluster


Actual results:

The new node may take several hours to apply the state


Expected results:

The new node should complete state transfer and application in a manageable time
