Understanding joins with Apache Spark

Understanding joins with Apache Spark

Workshop date & duration: June 20, 2020, 9:30 – 14:00, 30 min break included
TrainerValentina CrisanMaria Catana
Location: Online
Price: 150 RON (including VAT)
Number of places: 10
Languages: Scala & SQL

DESCRIPTION:

For a (mainly) in memory processing platform like Spark – getting the best performance is most of the time about:

  1. Optimizing the amount of data needed in order to perform a certain action   
  2. Having a partitioning strategy that distributed optimally the data to the Spark Cluster executors (this is many times correlated to the underlying storage data distribution for initial data distribution, but as well is related to how data is partitioned during the join itself, given that before running the actual join operation, the partitions are first sorted)
  3. And in case your action is a join one – choosing the right strategy for your joins 

This workshop will mainly focus on two of the above mentioned steps: partitioning and join strategy, making these aspects more clear through exercises and hands on sessions.

ETL with Apache Spark

ETL WITH APACHE SPARK

Workshop date & duration: March 28th, 2020, 9:30 – 14:00, 30 min break included
TrainerValentina CrisanMaria Catana
Location:  eSolutions Academy, Budişteanu Office Building, strada General Constantin Budişteanu Nr. 28C, etaj 1, Sector 1, Bucureşti
Price: 150 RON (including VAT)
Number of places: 10 no more places left
Languages: Scala & SQL

DESCRIPTION:

One of the many uses of Apache Spark is to transform data from different formats and sources, both batch and streaming data. In this workshop that will be mainly hands on we will focus on just that: understanding how we can read/write/transform/manage schema/join different formats of data and how is best to handle those data when it comes to Apache Spark. So, if you know a bit about Spark but did not manage to play too much with its ETL capabilities or even if you don’t know too much but would like to find out – this workshop might be of interest.
