thank you so much, for explaining step by step

[@abhi20aug]

very good content at one place in your channel, thanks for sharing it.

[@BeABetterDev]

Thank you Abhishek!

[@dahyelee8324]

Thanks a lot. It really helps :)

[@BeABetterDev]

You're very welcome!

[@jonzezk.4495]

The second method is pretty cool, it actually streams the file from S3 so you can process really large files with Lambda

[@sanjib1980]

For the second scenario I had to make slight correction in the code to make it work. Like below -
MappingIterator readValues = csvMapper.readerWithTypedSchemaFor(Person.class)
.with(schema)
.readValues(inputStream);

[@javiersanchez2314]

Great guidance, thanks a lot, maybe you have an example downloading a AWS S3 file to client's computer? thanks

[@Loserfr]

Very good content, but I would have loved to go through this with cloudformation ;)

[@BeABetterDev]

Next time! :)

[@shashwatkatiyar1377]

Hey Guys, Can anyone tell me from the above example that if we have an integer/double/long value in the POJO and if the csv file can have empty value for the same then if this code will work or what modification will be needed??

[@dnyaneshtathode5511]

What’s the way to download result csv to local, created by querying using Athena ?

[@BeABetterDev]

You would just need to go to the S3 destination bucket and download the file. Do you mean programmatically?

[@kritikatyagi6120]

In case of excel file what library we need to use in place of csvmapper

[@iamarvind]

is it possible to fetch 100 lines from S3 at a time ?

[@vasavimram1826]

Any video related to adding csv file to s3?

[@shahriddhijatinkumar1594]

Yes, I also want to know

[@vasavimram1826]

@@shahriddhijatinkumar1594 I found the way, you have to give metadata as "CSV" and make sure content is also in the way it fit into CSV file how u want to
