Tom Beerbower commented on AMBARI-3849:
---------------------------------------
To get a minimal response, use the query string parameter
*minimal_response=true*. This will remove all hrefs from the response. In
addition, only minimal resource id fields and explicitly requested fields will
be returned.
For example, the normal request ...
{code}
/api/v1/clusters/c1/hosts?fields=Hosts/host_status,host_components/HostRoles/state
{
"href" :
"http://c6401.ambari.apache.org:8080/api/v1/clusters/c1/hosts?fields=Hosts/host_status,host_components/HostRoles/state";,
"items" : [
{
"href" :
"http://c6401.ambari.apache.org:8080/api/v1/clusters/c1/hosts/c6401.ambari.apache.org";,
"Hosts" : {
"cluster_name" : "c1",
"host_name" : "c6401.ambari.apache.org",
"host_status" : "HEALTHY"
},
"host_components" : [
{
"href" :
"http://c6401.ambari.apache.org:8080/api/v1/clusters/c1/hosts/c6401.ambari.apache.org/host_components/DATANODE";,
"HostRoles" : {
"cluster_name" : "c1",
"component_name" : "DATANODE",
"host_name" : "c6401.ambari.apache.org",
"state" : "STARTED"
}
},
...
]
}
]
}
{code}
will look like this with *minimal_response=true* ...
{code}
/api/v1/clusters/c1/hosts?fields=Hosts/host_status,host_components/HostRoles/state&minimal_response=true
{
"items" : [
{
"Hosts" : {
"host_name" : "c6401.ambari.apache.org",
"host_status" : "HEALTHY"
},
"host_components" : [
{
"HostRoles" : {
"component_name" : "DATANODE",
"state" : "STARTED"
}
},
...
]
}
]
}
{code}
> Need ability to filter out href field in requests

> Key: AMBARI-3849
> URL: https://issues.apache.org/jira/browse/AMBARI-3849
> Project: Ambari
> Issue Type: Task
> Reporter: Tom Beerbower
> Assignee: Tom Beerbower
>
> On some API requests on large clusters, half the time is spent in generating,
> and half the time in transporting content. To cut down on the amount of
> content transported, we need a way to filter out the 'href' field.
> On a 2MB hosts response, 0.5MB is just the hrefs field.
