Description
Ref: MB-60349
From Morpheus,
The rebalance API "/controller/rebalance" now has a new parameter to specify a desired service topology for all services except kv (Data Service):
topology[<service>] = <list of nodes>
Example: -d topology[<service>]=otp_node1,otp_node2
<service> here is a name of the service – fts, index, n1ql, backup, cbas – kv is not supported
<list of nodes> list of nodes the service should reside in after the rebalance completion
fts: Search
index: GSI index
n1ql: Query
backup: Backup Service
cbas: Analytics
Example:
curl -u Administrator:password -X POST 172.23.108.69:8091/controller/rebalance \
|
-d "knownNodes=ns_1@172.23.108.69,ns_1@172.23.108.70,ns_1@172.23.108.71" \
|
-d "topology[index]=ns_1@172.23.108.70,ns_1@172.23.108.71" \
|
-d "topology[n1ql]=ns_1@172.23.108.69"

See comments for additional examples.
