Stormpot

an object pooling library for Java. Use it to recycle objects that are expensive to create. The library will take care of creating and destroying your objects in the background. Stormpot is very mature, is used in production, and has done over a trillion claim-release cycles in testing. It is faster and scales better than any competing pool.

Evolution of Babbel’s data pipeline on AWS: from SQS to Kinesis

Good “here’s how we found it” blog post:

Our new data pipeline with Kinesis in place allows us to plug new consumers without causing any damage to the current system, so it’s possible to rewrite all Queue Workers one by one and replace them with Kinesis Workers. In general, the transition to Kinesis was smooth and there were not so tricky parts. Another outcome was significantly reduced costs – handling almost the same amount of data as SQS, Kinesis appeared to be many times cheaper than SQS.
