I wasn't able to reproduce the issue. This is what I did:
1. Open
`pinot-tools/src/main/resources/examples/batch/airlineStats/airlineStats_offline_table_config.json`
and modified the `fieldConfigList` to add
``` json
{
"name": "DivAirportIDs",
"encodingType": "DICTIONARY",
"compressionCodec": "MV_ENTRY_DICT"
}
```
2. Started
`pinot-tools/src/main/java/org/apache/pinot/tools/GenericQuickstart.java`
3. Checked that `airlineStats.DivAirportIDs` was using `MV_ENTRY_DICT`. I
wasn't sure how to do this, so what I did was to add a breakpoint in both:
- `MultiValueFixedByteRawIndexCreator.java` constructor
- and `FixedBitMVEntryDictForwardIndexReader.java` constructor
4. Stopped the instance and delete temp data.
5. Modified `airlineStats_offline_table_config.json` again to change the
`fieldConfigList` to:
```json
{
"name": "DivAirportIDs",
"encodingType": "DICTIONARY",
"indexes": {
"forward": {
"dictIdCompressionType": "MV_ENTRY_DICT"
}
}
}
```
6. Started `GenericQuickstart` again.
7. Checked that `airlineStats.DivAirportIDs` was using `MV_ENTRY_DICT` doing
the same as before.
In both cases it looks like MV_ENTRY_DICT is being used. Am I missing
something?
