Apache Spark DataFrame caching with Alluxio

Many organizations deploy Alluxio together with Spark for performance gains and data manageability benefits. Qunar recently deployed Alluxio in production, and their Spark streaming jobs sped up by 15x on average and up to 300x during peak times. They noticed that some Spark jobs would slow down or would not finish, but with Alluxio, those jobs could finish quickly. In this blog post, we investigate how Alluxio helps Spark be more effective. Alluxio increases performance of Spark jobs, helps Spark jobs perform more predictably, and enables multiple Spark jobs to share the same data from memory.

Arimo Leverages Alluxio’s In-Memory Capability, Improving Time-to-Results for Deep Learning Models

Deep learning algorithms have traditionally been used in specific applications, most notably, computer vision, machine translation, text mining, and fraud detection. Deep learning truly shines when the model is big and trained on large-scale datasets. Meanwhile, distributed computing platforms like Spark are designed to handle big data and have been used extensively. Therefore, by having deep learning available on Spark, the application of deep learning is much broader, and now businesses can fully take advantage of deep learning capabilities using their existing Spark infrastructure.
