We do not have any native service that can do that. The services that you can use as a topic are EventBridge and SNS, and both of them have a payload size limit of 256KB. What customers usually do is save the object to S3 and send on the topic the details of the object so they can retrieve it themselves.
You can also use MSK (Managed Streaming for Kafka) which allows payload size of up to 8 MB.
Can you share me reference link how to publish file in SNS and EventBridge through java code?
Sorry, but I do not have any such code, but the code should very loosely look something like:
bucket_name = "bucket"; object_name = "my_object"; s3.upload_file(bucket_name, object_name, local_file); message = { "bucket_name": bucket_name, "object_name": object_name }; sns.public_message(topic_name, message);
