> HoodieTestDataGenerator is used to generate sample data for unit-tests. It
> allows generating HoodieRecords for insert/update/delete. It maintains the
> record keys in a HashMap.
> private final Map<Integer, KeyPartition> existingKeys;
> There are two issues in the implementation:
> # Delete from existingKeys uses KeyPartition rather than Integer keys
> # Inserting records after deletes is not correctly handled
> The implementation uses the Integer key so that values can be looked up
> randomly. Assume three values were inserted, then the HashMap will hold:
> 0 -> KeyPartition1
> 1 -> KeyPartition2
> 2 -> KeyPartition3
> Now if we delete KeyPartition2 (generate a random record for deletion), the
> HashMap will be:
> 0 -> KeyPartition1
> 2 -> KeyPartition3
>
> Now if we issue a insertBatch() then the insert is
> existingKeys.put(existingKeys.size(), KeyPartition3) which will overwrite the
> KeyPartition3 already in the map rather than actually inserting a new entry
> in the map.
