Utiliser Apache Spark en cluster
http://aseigneurin.github.io/2014/11/13/utiliser-apache-spark-en-cluster.html
Utiliser Apache Spark en cluster. Dans les précédents posts, nous avons utilisé Apache Spark avec un exécuteur unique. Spark étant un framework de calcul distribué, nous allons maintenant monter un cluster en mode. Un cluster Spark se compose d’un master. Et d’un ou plusieurs workers.

Kafka Streams - Scaling up or down
http://aseigneurin.github.io/2016/10/07/kafka-streams-scaling-up-or-down.html
Kafka Streams - Scaling up or down. Kafka Streams is a new component of the Kafka platform. It is a lightweight library designed to process data from and to Kafka. In this post, I’m not going to go through a full tutorial of Kafka Streams but, instead, see how it behaves as regards to scaling. By scaling, I mean the process of adding or removing nodes to increase or decrease the processing power. To do so, Kafka Streams will register all the instances of your application in the same. I have also created ...
Spark - File formats and storage options
http://aseigneurin.github.io/2016/11/08/spark-file-formats-and-storage-options.html
Spark - File formats and storage options. I recently worked on a project in which Spark was used to ingest data from text files. The team was struggling to read the files with acceptable performance. That lead me to analysing a few options that are offered to you when using Spark. I am reviewing them here. The files are received from an external system, meaning we can ask to be sent a compressed file but not more complex formats (Parquet, Avro). Options to be tested. I tested multiple combinations:.

Spark & Kafka - Achieving zero data-loss
http://aseigneurin.github.io/2016/05/07/spark-kafka-achieving-zero-data-loss.html
Spark and Kafka - Achieving zero data-loss. Kafka and Spark Streaming are two technologies that fit well together. Both are distributed systems so as to handle heavy loads of data. Making sure you don’t lose data does not come out-of-the-box, though, and this post aims at helping you reach this goal. TL;DR - Connect to Kafka using Spark’s Direct Stream approach and store offsets back to ZooKeeper (code provided below) - Don’t use Spark Checkpoints. Overview of the problem. Messages can be lost). That bei...
