Grubhub is the nation's leading online and mobile food ordering company dedicated to connecting hungry diners with local takeout restaurants. It serves about 20 million active diners by connecting to 80000+ local restaurants and processing 500000+ orders per day. Due to exponential growth that the company is now seeing, bigdata problem is quite inevitable. If we see GRUBHUB through 4 V's of bigdata:Volume – being nation's leading food delivery platform, serving about 20 million diners over 1600 cities, so, huge data volume is obvious. Velocity - Number of orders that are being processed on daily basis is standing at ~500000. Each order must deal with multiple facades of data such as order management, restaurant connect, diners, delivery e.t.c which implies data being accumulated at a greater rate. To study the dynamic nature of the data, realtime and near realtime based data analytics is taking the lead over daily batch processes.Variety - being a highly data driven company, top level management likes to see 360 degree of each entity part of GRUBHUB’s ecosystem. To achieve this, right from geo information to clickstream data, doors are open to all varieties of data. It can be of various formats such as text, raw images, structured or unstructured.Veracity - forecasting metrics is quite challenging due to its continuous behavior in daily data trends, exploring historical data is much needed to solve the inconsistency in forecasting stable metrics.By looking at all the 4 V data characteristics listed above, it is obvious that GRUBHUB is a perfect place for BIGDATA case study as we adopt cutting edge technologies as we evolve. big data, hadoop, hdfs, hive, sqoop, pig, presto, apache spark, python, pyspark, spark SQL, spark dataframes, aws emr, aws s3, aws redshift, ETL, UNIX, SQL, OLAP, RDBMS, mysql, cloud, github, jenkins, azkaban, JIRA , redash/tableau are few of the tools / technologies we use on daily basis.
