11.3.1 How to make the number of keys uniform in all ranges
This subsection explains how to arrange the EADS server positions (hash values) evenly to make the number of keys uniform in all ranges.
- Organization of this subsection
(1) Terminate all EADS servers in the cluster (after exporting data to files)
Export data to files and then terminate all EADS servers in the cluster.
For details about this procedure, see 10.5 Terminating the EADS servers (after exporting data from memory to files).
(2) Change the cluster properties
To adjust the EADS server positions (hash values) automatically, change each EADS server's cluster properties.
Delete from each EADS server's cluster property file all the eads.node.EADS-server-ID.position parameters.
(3) Start the EADS servers (import data from files)
Start all EADS servers in the cluster, and then import back into memory the data that was exported to files during the previous session.
For details about the procedure, see 10.3 Starting the EADS servers (and creating caches by importing data from files).
