I'm migrating our previous Greengrass v1 system to v2. We have an "upload" lambda function that's the final step for our data and its job is to upload the data to an S3 bucket. In v1 this was done with the AWS SDK using s3.putObject().
Since we're migrating to v2 it seems like a better solution to use the StreamManager to upload the data to S3. Something I don't understand though is that it seems like the only way to add the data to StreamManager is by giving it a file URL. This is the example from the docs.
const taskDefinition = new S3ExportTaskDefinition()
.withBucket("BucketName")
.withKey("KeyName")
.withInputUrl("URLToFile");
The data that the upload function is operating on is coming from Redis at this point in its journey. So if I'm understanding this correctly, I'll need to get the data from Redis, write it to a file in a mounted volume of the lambda, and then give that file to the S3ExportTaskDefinition(). This seems a little involved and I'm wondering if I'm missing something here. Is there a way to simply give the StreamManager export task a buffer or string?
