Shawn Feldman updated USERGRID-739:
-----------------------------------
Description:
When allocating an index alias to one of the physical indexes a bucketing
strategy should be used with ranges based off the number of indexes in
elasticsearch.
For example, if there are 10 physical indexes then there would be 10 buckets
based on a hash of the Application ID which would result in the assignment of
an app alias to a physical index based on the range in which it falls.
#Cluster Naming
clusterName = config{usergrid.cluster_name}
keyspaceName = config{cassandra.keyspace.application}
managementName = config{elasticsearch.managment_index}
indexRoot = {clusterName}_{keyspaceName}
managementIndexName = {indexRoot}_{managementName}
managementAliasName = {indexRoot}_{managementName}_read_alias ||
{indexRoot}_{managementName}_read_alias
applicationIndexName = {indexRoot}_applications_{bucketId}
applicationAliasName = {indexRoot}_{appId}_read_alias ||
{indexRoot}_{appId}_write_alias
