To test scanning multi-value dimensions, I created 200 events (see attached
events file - sample-tdms-kafka-event.zip) that I send to a topic (tdms) on
Kafka. I configure Druid's Kafka indexing service with corresponding
supervisor spec (tdms-kafka-supervisor.zip). When I do a scan on a value in
the multi-value dimension, I get most of the rows barring a few. For example
if I scan for "p1-TX-LO-Out 3", I get only 64 rows returned instead of 67.
When I do a search it tells me there are 67 rows.
Here is my query for scan:
{
"queryType" : "scan",
"dataSource" : "tdms",
"resultFormat": "list",
"columns" : [],
"filter": { "type": "selector", "dimension": "groupNames", "value":
"p1-TX-LO-Out 3" },
"intervals": [
"2017-01-01T00:00:00.000/2019-01-01T00:00:00.000"
]
}

I am using druid version 0.12.2 on my Ubuntu 16.04 following the quickstart
tutorial on druid.io
