Call AWS lambda service in Glue script

Hello Gonzalo, Yes I was thinking same to call lambda as part of UDF . Thanks for confirming this. Just one more thing I would like to ask , will these call to lambda be synchronous .

Lets say if I have 100 rows in dataframe . Then lambda will called 100 times in parallel for each row and whole process gets completed once we get result for each row ( be it correct result or failure ).

Yes, you can call lambda via boto3 inside your Glue code.
The issue is that if you do it distributed on the data (if you mean Glue for Spark) is a bit more complicated and you are likely to get throttling errors and much higher cost than if you did that same lambda code inside a Glue udf (or even better SparkSQL)
