spark-py-notebooks - Apache Spark & Python (pySpark) tutorials for Big Data Analysis and Machine Learning as IPython / Jupyter notebooks

  •    Jupyter

This is a collection of IPython notebook/Jupyter notebooks intended to train the reader on different Apache Spark concepts, from basic to advanced, by using the Python language. If Python is not your language, and it is R, you may want to have a look at our R on Apache Spark (SparkR) notebooks instead. Additionally, if your are interested in being introduced to some basic Data Science Engineering, you might find these series of tutorials interesting. There we explain different concepts and applications using Python and R.

Gaffer - A large-scale entity and relation database supporting aggregation of properties

  •    Java

Gaffer is a graph database framework. It allows the storage of very large graphs containing rich properties on the nodes and edges. Several storage options are available, including Accumulo, Hbase and Parquet. It is designed to be as flexible, scalable and extensible as possible, allowing for rapid prototyping and transition to production systems.

spark-movie-lens - An on-line movie recommender using Spark, Python Flask, and the MovieLens dataset

  •    Jupyter

This Apache Spark tutorial will guide you step-by-step into how to use the MovieLens dataset to build a movie recommender using collaborative filtering with Spark's Alternating Least Saqures implementation. It is organised in two parts. The first one is about getting and parsing movies and ratings data into Spark RDDs. The second is about building and using the recommender and persisting it for later use in our on-line recommender system. This tutorial can be used independently to build a movie recommender model based on the MovieLens dataset. Most of the code in the first part, about how to use ALS with the public MovieLens dataset, comes from my solution to one of the exercises proposed in the CS100.1x Introduction to Big Data with Apache Spark by Anthony D. Joseph on edX, that is also publicly available since 2014 at Spark Summit. Starting from there, I've added with minor modifications to use a larger dataset, then code about how to store and reload the model for later use, and finally a web service using Flask.

magellan - Geo Spatial Data Analytics on Spark

  •    Scala

Magellan is a distributed execution engine for geospatial analytics on big data. It is implemented on top of Apache Spark and deeply leverages modern database techniques like efficient data layout, code generation and query optimization in order to optimize geospatial queries. The application developer writes standard sql or data frame queries to evaluate geometric expressions while the execution engine takes care of efficiently laying data out in memory during query processing, picking the right query plan, optimizing the query execution with cheap and efficient spatial indices while presenting a declarative abstraction to the developer.

Gimel - PayPal's Big Data Processing Framework

  •    Scala

Gimel provides unified Data API to access data from any storage like HDFS, GS, Alluxio, Hbase, Aerospike, BigQuery, Druid, Elastic, Teradata, Oracle, MySQL, etc.

ethz-web-scale-data-mining-project - ETH Zurich - Web Scale Data Processing and Mining Project

  •    HTML

This is the main repository for the web scale data mining project, which took place in summer 2014 as a research project. One of the results are the visualized topics, which have been learned autonomously from terabytes of raw HTML data.

succinct - Enabling queries on compressed data.

  •    Java

Succinct is a data store that enables queries directly on a compressed representation of data. This repository maintains the Java implementations of Succinct's core algorithms, and applications that exploit them, such as a Apache Spark binding for Succinct. The Succinct-Core module contains Java implementation of Succinct's core algorithms. See a more descriptive description of the core module here.

rsparkling - RSparkling: Use H2O Sparkling Water from R (Spark + R + Machine Learning)

  •    R

Please submit issues, questions and PRs in the new location. The current repo is not maintained. The repository has been moved for several reasons, mainly to improve the integrations with Sparkling Water and for the stability reasons.

spark-on-lambda - Apache Spark on AWS Lambda

  •    Scala

AWS Lambda is a Function as a Service which is serverless, scales up quickly and bills usage at 100ms granularity. We thought it would be interesting to see if we can get Apache Spark run on Lambda. This is an interesting idea we had, in order to validate we just hacked it into a prototype to see if it works. We were able to make it work making some changes in Spark's scheduler and shuffle areas. Since AWS Lambda has a 5 minute max run time limit, we have to shuffle over an external storage. So we hacked the shuffle parts of Spark code to shuffle over an external storage like S3. This is a prototype and its not battle tested possibly can have bugs. The changes are made against OS Apache Spark-2.1.0 version. We also have a fork of Spark-2.2.0 which has few bugs will be pushed here soon. We welcome contributions from developers.

sparkling-graph - SparklingGraph provides easy to use set of features that will give you ability to proces large scala graphs using Spark and GraphX

  •    Scala

SparklingGraph provides easy to use set of features that will give you ability to proces large scala graphs using Spark and GraphX. Bartusiak et al. (2017). SparklingGraph: large scale, distributed graph processing made easy. Manuscript in preparation.

metorikku - A simplified, lightweight ELT Framework based on Apache Spark

  •    Scala

Metorikku is a library that simplifies writing and executing ETLs on top of Apache Spark. A user needs to write a simple YAML configuration file that includes SQL queries and run Metorikku on a spark cluster. The platform also includes a way to write tests for metrics using MetorikkuTester. To run Metorikku you must first define 2 files.
