Comparison of Spark vs R Business Analytics Group R at Eastman R is the primary tool for analyzing business data at Eastman Analysis is done in-memory
Typical analyst workstation has 16Gb of RAM Servers have more Single threaded* Are ways to leverage multiple cores/threads but doesnt always work Apache Spark Spark is so hot right now!
Includes machine learning, graph analytics and more Fast and scalable Replaces MapReduce with a SQL like language Can use HDFS and other filesystems Tradeoff We know R very well
Most of our datasets today fit in memory Development ecosystem and workflow is already established Scalable to handle big data Native multi-threading with machine learning should be faster even on medium size problems Spark is new and unknown to us requires training and
change management Capstone project When should one switch to Spark from R? Given increasingly larger (rows and columns) data sets, how does Spark performance compare to R in fitting different basic models (e.g. linear regression)? How does a single instance of Spark compare to a small cluster (in AWS for example)?
Deliverable Eastman would like a report detailing at what point (size of data) the performance of Spark significantly exceeds that of R. We would use this information to make decisions regarding when to begin implementing Spark for analytics at Eastman. Support Many large, public datasets are available to use with this
project. If needed, Eastman will recommend one or more specific large datasets Eastman can provide analytics expertise (e.g. linear regression, logistic regression, etc.) if needed Why choose this project? A chance to get practical experience with Spark for your
resume (it really is hot right now) A chance to get practical experience (or more experience) with distributed processing A chance to learn more about analytics (analytics + computer science = $$$ in the job market) SQL vs NoSQL Performance with text Business Analytics Group
Text Analytics at Eastman Eastman generates a lot of text in the form of call reports written by our salesforce after visiting a customer. Recently, web scraping has been added as a source of text data to help us identify consumer sentiment towards chemicals and products of interest. Text analytics is performed on this data to help pull out significant themes and trends.
SQL at Eastman The majority of Eastmans data is stored in a SQL database of some type. The data is typically modelled with a star schema Avoids replication of dimensional data Reasonably fast Web scraped data is currently stored in a star schema form
NoSQL Not Only SQL is a class of database management systems that are designed to handle specific types of data storage challenges Key Value Pairs Graph Databases Document Stores etc Why is there excitement about this emerging class of databases?
Data such as text is coming with more variety than traditional data sources and is increasingly a poor fit with relational databases and predefined data models New database designs along with ever-increasing compute power are making schema-on-read feasible
Much better fit with unstructured or variable data such as text New database designs work increasingly well in a distributed fashion and are more amenable to big data Text is one of the bigger forms of data. Deliverables Eastman would like a report detailing performance
comparisons of SQL (e.g. MySQL, SQL Server Express) vs NoSQL (e.g. MongoDB) on a database containing hundreds/thousands of reviews. We would use this data to make decisions regarding our long-term technology strategy for storing text data. Support Eastman will provide review data, if needed Publicly available text data sets are also available, which
Eastman could recommend Eastman will provide technical assistance, if needed, in web scraping new reviews Why choose this project? A chance to get practical experience with NoSQL databases, which are increasing rapidly in popularity and are a nice resume addition A chance to get practical experience with web scraping
Interest in text as a data source is booming and web scraping is important as a way to acquire text data
