Building more efficient data applications with Rust means lower cloud costs but also more climate-friendly software. Rust-based data pipelines can be an order of magnitude smaller than their JVm counterparts, leading to massive savings in power and compute consumption.

Serverless data ingestion can be extremely cost effective but limitations of AWS Lambda can result in transaction log bloat. In this post we'll discuss the "BUFFER_MORE" feature in sqs-ingest and how it helps get more bang for your Lambda buck.

Facing a large backlog of data it is tempting to horizontally scale Delta writers as much as compute and budget will allow. In this post we'll dive into how this can be counter propductive and actually slow throughput rather than accelerate it!

At a protocol level Delta Lake can scale to an infinite number of concurrent readers and writers, in theory, so long as the underlying storage provider supports strong atomicity. On AWS the Simple Storage Service lacks a necessary "put if absent" operation which requires Delta writers coordinate to ensure consistent writes to any given table.
