Module s3 

Available on crate feature s3 only.

S3 Tasklet

This module provides tasklets for Amazon S3 file transfer operations (put and get). It is designed to be similar to Spring Batch’s S3 capabilities for batch file transfers.

Features

• S3 PUT operations (upload local files to S3)
• S3 GET operations (download S3 objects to local files, streaming)
• S3 PUT FOLDER operations (upload entire local folder to an S3 prefix)
• S3 GET FOLDER operations (download all objects under an S3 prefix to a local folder)
• Explicit credential configuration (access key / secret key)
• AWS default credential chain (environment variables, ~/.aws/credentials, IAM role)
• Custom endpoint URL for S3-compatible services (MinIO, LocalStack)
• Configurable multipart upload chunk size

Examples

S3 PUT Operation

use spring_batch_rs::tasklet::s3::put::S3PutTaskletBuilder;

let tasklet = S3PutTaskletBuilder::new()
    .bucket("my-bucket")
    .key("exports/file.csv")
    .local_file("./output/file.csv")
    .region("eu-west-1")
    .build()?;

S3 GET Operation

use spring_batch_rs::tasklet::s3::get::S3GetTaskletBuilder;

let tasklet = S3GetTaskletBuilder::new()
    .bucket("my-bucket")
    .key("imports/file.csv")
    .local_file("./input/file.csv")
    .region("eu-west-1")
    .build()?;

S3 with MinIO (custom endpoint)

use spring_batch_rs::tasklet::s3::put::S3PutTaskletBuilder;

let tasklet = S3PutTaskletBuilder::new()
    .bucket("my-bucket")
    .key("file.csv")
    .local_file("./output/file.csv")
    .endpoint_url("http://localhost:9000")
    .access_key_id("minioadmin")
    .secret_access_key("minioadmin")
    .build()?;
