Review Comment:
I have added a private method. but as of now, not using it in many places.
if I come across more, will re-use.

Review Comment:
this is an optimization.
previously, we had to explicitly check for operation type here
https://github.com/apache/hudi/blob/c9069fe5794840971c1710034b08a0f36f53518e/hudi-common/src/main/java/org/apache/hudi/common/table/read/buffer/StreamingFileGroupRecordBufferLoader.java#L91
but now, we have removed that. and its working w/o any additional fix, since
we fixed the `HoodieRecord` inherently to track this

Review Comment:
we end up calling `AvroConversionUtils.createDataFrame` (
https://github.com/apache/hudi/blob/c9069fe5794840971c1710034b08a0f36f53518e/hudi-client/hudi-spark-client/src/main/scala/org/apache/hudi/AvroConversionUtils.scala#L116
)
which in turn ends up calling `AvroDeserializer` to deserialize avro
records.
and we end up w/ below exception if not for above fix.

```
In other words,
`data` goes through ser and deser while creating dataframe, and hence the
genericRecord in `SerializableIndexedRecord` is converted to binary. So, unless
we call `decodeRecord(Schema)` which can only be invoked from within
`HoodieAvroIndexedRecord`, I could not find a way out apart from converting to
GenericRecords within `toDataset` here.
