Tom Beerbower commented on AMBARI-1844:
---------------------------------------
Specify a set of RequestInfo/Body pairs in a single request body for a PUT as
follows ... Note that each RequestInfo contains a query string so you can
attach each Body to a different host as shown.
{code}
[
{
"RequestInfo":{
"query":"Hosts/host_name=host1"
},
"Body":
{
"Hosts": {
"desired_config": {
"type": "global",
"tag": "version50",
"properties": { "a": "b", "x": "y" }
}
}
}
},
{
"RequestInfo":{
"query":"Hosts/host_name=host2"
},
"Body":
{
"Hosts": {
"desired_config": {
"type": "global",
"tag": "version51",
"properties": { "a": "c", "x": "z" }
}
}
}
}
]

>
> Currently when we save host-overrides configuration, we have to do PUT of the
> delta on each host (documented in BUG-3775).
> This is problematic if admin provides an exception to 100 hosts. This will
> require 100 PUT calls which is expensive. There is a bulk update mechanism,
> but that requires the same content for all 100 hosts. This will not be the
> case if any hosts have other properties that are overridden.
> To save on network calls, we would like to request a bulk update mechanism.
