clintropolis opened a new pull request #10422:
URL: https://github.com/apache/druid/pull/10422
### Description
Adds a light weight verison of `/druid/coordinator/v1/lookups/nodeStatus`,
which currently include the lookup spec JSON, which can be sort of large for
inline map lookups:
```json
{
"__default": {
"localhost:8083": {
"current": {
"lookup_table": {
"version": "2020-06-11T10:48:17.033Z",
"lookupExtractorFactory": {
"type": "cachedNamespace",
"extractionNamespace": {
"type": "uri",
"uri": null,
"uriPrefix":
"file:/Users/clint/workspace/data/druid/lookups/lookup-simple.json",
"fileRegex": null,
"namespaceParseSpec": {
"format": "simpleJson"
},
"pollPeriod": "PT0S"
},
"firstCacheTimeout": 0,
"injective": true
}
}
},
"toLoad": {},
"toDrop": []
}
}
}
```
Using `/druid/coordinator/v1/lookups/nodeStatus?detailed=false` will instead
just include the 'version' string instead of the complete lookup JSON spec:
```json
{
"__default": {
"localhost:8083": {
"current": {
"lookup_table": "2020-06-11T10:48:17.033Z"
},
"toLoad": {},
"toDrop": []
}
}
}
```
The new parameter defaults to true if not set to preserve existing behavior.
