Using Power Query
Data retrieval example from Apache Druid with authentication. Put following snippet into Microsoft Excel Power Query’s Advanced Editor (New Query > From Other Sources > Blank Query
):
let
url = "http://<druid-host>:8888/druid/v2/sql/",
headers = [#"Content-Type" = "application/json", #"Authorization" = "Basic <druid-credentials-encoded-base64>"],
postData = Text.ToBinary("{""query"": ""select * from wikipedia limit 10000"",""resultFormat"":""csv"",""header"":""true""}"),
response = Web.Contents(
url,
[
Headers = headers,
Content = postData
]
),
csvResponse = Csv.Document(response)
in
csvResponse
<druid-credentials-encoded-base64>
is username:password
format.
Also note that authentication type on Power Query must be anonymous (default).
Using CLI
Create a new file , for example, named query.json
containing following content:
{
"queryType" : "topN",
"dataSource" : "wikipedia",
"intervals" : ["2016-06-27/2016-06-28"],
"granularity" : "all",
"dimension" : "page",
"metric" : "count",
"threshold" : 10,
"aggregations" : [
{
"type" : "count",
"name" : "count"
}
]
}
Execute following shell command (curl
is required but jq
is optional):
$ curl -sS -X 'POST' -H 'Content-Type:application/json' -d @query.json http://<username>:<password>@<druid-host>:8888/druid/v2 | jq
