Hey @nsivabalan, the `bulk_insert` job has been finished successfully, the
efficiency is really amazing. However there are still duplicates as I checked,
even though I enabled `hoodie.combine.before.insert`.
Full config details I used as below:
```
val hudiOptions = Map[String,String](
HoodieWriteConfig.TABLE_NAME -> "recordings_hudi",
HoodieWriteConfig.COMBINE_BEFORE_INSERT_PROP -> "true",
DataSourceWriteOptions.ENABLE_ROW_WRITER_OPT_KEY -> "true",
DataSourceWriteOptions.OPERATION_OPT_KEY ->
DataSourceWriteOptions.BULK_INSERT_OPERATION_OPT_VAL,
DataSourceWriteOptions.KEYGENERATOR_CLASS_OPT_KEY ->
"org.apache.hudi.keygen.NonpartitionedKeyGenerator",
DataSourceWriteOptions.TABLE_TYPE_OPT_KEY -> "COPY_ON_WRITE",
DataSourceWriteOptions.RECORDKEY_FIELD_OPT_KEY -> "sid",
DataSourceWriteOptions.PRECOMBINE_FIELD_OPT_KEY ->
"date_updated")
```
There are duplicates with same `sid` and different `data_update` field.
Any insight on it?
