Hi @teyeheimans,
What type of lookup are you creating?
### Map Lookup
* With the following configuration,
```
{
"type": "map",
"map": {
"1": "One",
"2": "Two",
"3": "Three"
}
}
```
I do see the key-value pairs, keys and values correctly, and formatted as a
JSON
```
$ curl -X GET http://localhost:8888/druid/v1/lookups/introspect/mapLookup/
{"1":"One","2":"Two","3":"Three"}
$ curl -X GET
http://localhost:8888/druid/v1/lookups/introspect/mapLookup/keys
[1, 2, 3]
$ curl -X GET
http://localhost:8888/druid/v1/lookups/introspect/mapLookup/values
[One, Two, Three]
$ curl -X GET
http://localhost:8888/druid/v1/lookups/introspect/mapLookup/version
-- Does not return anything
```
- `/version` endpoint is not implemented in
`MapLookupIntrospectionHandler` ; hence, we do not see the response.
### cachedNamespace Lookup
* With the following configuration
```
{
"type": "cachedNamespace",
"extractionNamespace": {
"type": "uri",
"uri": "file:/tmp/sampleCSV.csv",
"namespaceParseSpec": {
"format": "csv",
"columns": [
"key",
"value"
],
"skipHeaderRows": 1
},
"pollPeriod": "PT30S"
},
"firstCacheTimeout": 0
}
```
I see all the endpoints returning responses:
```
$ curl -X GET http://localhost:8888/druid/v1/lookups/introspect/csvLookup/
{"20":"Twenty","10":"Ten","30":"Thirty"}
$ curl -X GET
http://localhost:8888/druid/v1/lookups/introspect/csvLookup/keys
["20","10","30"]
$ curl -X GET
http://localhost:8888/druid/v1/lookups/introspect/csvLookup/values
["Twenty","Ten","Thirty"]
$ $ curl -X GET
http://localhost:8888/druid/v1/lookups/introspect/csvLookup/version
{"version":"1729184323236"}
```
* One caveat to call out here is `/version` endpoint does not return the
version which was set manually when lookup was being created, but the epoch
time. I see version as `v1` on the Console, but `1729184323236` on the
Introspect API response.
Thanks!
