Is there a concurrent read write limit on a s3 file

Question

Is there a limit on the number of simultaneous/concurrent read/write operations on a single file stored in AWS S3? I'm thinking of designing a solution which requires parallel processing of some large amount of data stored in a single file which means there will be multiple read/write operations at any given point on time. I want to understand if there is a limit for this. Consistency of data is not required for me.
