Load data into Redshift from S3 buckets using a pre-canned Lambda function. Looks like it may be a good example of production-quality Lambda

Continuous Delivery with ETL Systems [video]
Lonely Planet and Dr Foster Intelligence both make heavy use of ETL in their products, and both organisations have applied the principles of Continuous Delivery to their delivery process.
Some of the Continuous Delivery norms need to be adapted in the context of ETL, and some interesting patterns emerge, such as running Continuous Integration against data, as well as code.

ETL for America
This is a really good post on governmental computing, open data, and so on:
The fact that I can go months hearing about "open data" without a single mention of ETL is a problem. ETL is the pipes of your house: it's how you open data.

Cloudera Impala 1.0: It’s Here, It’s Real, It’s Already the Standard for SQL on Hadoop
we are proud to announce the first production drop of Impala, which reflects feedback from across the user community based on multiple types of real-world workloads. Just as a refresher, the main design principle behind Impala is complete integration with the Hadoop platform (jointly utilizing a single pool of storage, metadata model, security framework, and set of system resources). This integration allows Impala users to take advantage of the time-tested cost, flexibility, and scale advantages of Hadoop for interactive SQL queries, and makes SQL a first-class Hadoop citizen alongside MapReduce and other frameworks. The net result is that all your data becomes available for interactive analysis simultaneously with all other types of processing, with no ETL delays needed.


Along with some great benchmark numbers against Hive. nifty stuff
