amazon web services - Using AWS Lambda to transform files on S3 -

-

i have simple scenario. use lambda load multiple 100mb files s3 (every 1-10 seconds new file(s) land on s3), transform them (minor changes) , store them on different s3 bucket.

the problem in java program (running on aws lambda) giving memory overflow errors though allocated 1024md ram. load complete files in ram. not sue why happens.

i have following questions:

  1. without filling ram, approach read, transform , write 100mb files on s3 repeatedly , concurrently? lambda choice case?
  2. why memory getting full though allocated 1024 memory through web ui?
