Reading modes in spark

Hello Everyone,

🌟 3 type of reading mode into pyspark:

1.Permissive Mode : its a default mode. if spark is not able to parse it due to dattype mismatch then make it as null without impacting other result, i.e only issue record are null others are fine.

2.DROPMALFORMED : whatever record having parsing issue, i.e in any column there is issues it will totally ignore that record, it only show correct record.

3.FailFast Mode : while reading data into this mode it will fail as soon as it encounters any record have parsing issues.
