Pre-requisites: knowledge of distributed systems, Hadoop ecosystem (HDFS, MapReduce), know a bit of SQL.

Description:

There are a few concepts and solutions that solutions architects should be aware of when evaluating or building a big data solution: what data partitioning means, how to model your data in order to get the best performance from your distributed system, what is the best format of your data, what is the best storage or the best way to analyze your data. Solutions like HDFS, Hive, Cassandra, Hbase, Spark, Kafka, YARN should be known – not necessarily because you will work specifically with them – but mainly because knowing the concepts of these solutions will help you understand other similar solutions in the big data space. This course is designed to make sure the participants will understand the usage and applicability of big data technologies like HDFS, Spark, Cassandra, Hbase, Kafka ,..  and which aspects to consider when starting to build a Big Data architecture.

Getting started with Machine Learning can seem a pretty hefty task to some people: understanding the algorithms, learning a bit of programming, deciding which libraries to use, getting some data to learn on, etc… But in reality if you’re actually setting your expectations right and willing to start small and learn step by step, learning the basics of ML it’s actually quite doable. After learning a bit it’s actually up to you to take your knowledge in the real world and apply and expand what you have learned.

This workshop aims to introduce you into ML world and to teach you how to solve classification and regression problems through the usage of decision trees and random forest algorithms. We will go from the theory to hands on in just a couple of hours aiming mostly to make you understand the main pipeline of an ML project, while of course learning a bit of ML:

    • Software and hardware requirements for a ML project
    • Common Python libraries for data analysis
    • Feature encoding and feature preprocessing
    • Exploratory Data Analysis (EDA)
    • Model validation
    • Model hyperparameter optimization
    • Tree based models for classification and regression:
      • Decision Tree
      • Random Forest
    • Repetitive model improvement

workshop Spark Structured Streaming vs Kafka Streams

Date: TBD
Trainers: Felix Crisan, Valentina Crisan, Maria Catana
Location: TBD
Number of places: 20
Price: 150 RON (including VAT)

Streams processing can be solved at application level or cluster level (stream processing framework) and two of the existing solutions in these areas are Kafka Streams and Spark Structured Streaming, the former choosing a microservices approach by exposing an API and the later extending the well known Spark processing capabilities to structured streaming processing.

This workshop aims to discuss the major differences between the Kafka and Spark approach when it comes to streams processing: starting from the architecture, the functionalities, the limitations in both solutions, the possible use cases for both and some of the implementation details.

Streams processing is one of the most active topics in big data architecture discussions nowadays, with many open and proprietary solutions available on the market ( Apache Spark Streaming, Apache Storm, Apache Flink, Google DataFlow..). But starting with release 0.11.0.0 Apache Kafka as well introduced the capability to process the streams of data that flow through Kafka – thus understanding what you can do with Kafka Streams and how is different from other solutions in the market it’s key in knowing what to choose for your particular use case.

This workshop aims to cover the most important parts of Kafka streams: the concepts (streams, tables, handling state, interactive queries, .. ), the practicality (what can you do with it and what is the difference between the API and the KSQL server) and to explain what means building an application that uses Kafka Streams. We will be focusing on the stream processing part of Kafka, assuming that participants are already familiar with the basic concepts of Apache Kafka – the distributed messaging bus.

Introduction to Neo4j

marcatana1 Comment
Description:

This workshop aims to cover various introductory topics in the area of graph databases, with a main focus on Neo4j. We will tackle subjects relating to data modelling, performance and scalability. We will then have a look at how this technology can be used to highlight valuable patterns within our data.

The workshop will be divided into three main parts: a presentation covering the theoretical aspects surrounding graph databases, a demo showcasing typical Neo4j usage and a hands-on lab activity.

Introduction to Apache Kafka

marcatanaLeave a comment

Apache Kafka is positioning strongly lately as Kafka as a Platform, quite an evolution from the messaging bus build by LinkedIn in 2011. But what makes Apache Kafka market such a strong position in the big data architecture landscape: highly distributed infinite (theoretically at least) storage of data, streaming features and API, KSQL? In this workshop we will go through the main features of Apache Kafka and discuss its evolved position in a big data architecture through use cases and through a hands on session in which we will store data through producers API, retrieve data through consumers API, see how data is partitioned and replicated, we will process data stored in Kafka through Kafka streams using KSQL. This workshop is entry level and addresses anyone interested in understanding how to get started with Apache Kafka and the role this solution can play in a big data architecture

Open course: Intro to Big Data Hadoop Architecture

Dates: 18-20 May, 2018

Location: eSolutions Academy, Budişteanu Office Building, strada General Constantin Budişteanu Nr. 28C, etaj 1, Sector 1, Bucureşti.
Number of places: 15

We have decided, together with our partners from eSolutions Academy, to organize an open course for Big Data introduction. Together with Felix we’ve been (delivered) through many and varied Big Data courses in the past 2 years, thus we believe we have the general understanding needed in order to approach the general architecture level of a Big Data solution for a class of people coming from different backgrounds thus having different expectations and maybe use cases in mind. We asked eSolutions to help with organizing and the logistics of the course, thus all the registration process goes through them. We look forward seeing you at the course.

Introduction to Apache Solr

marcatanaLeave a comment

This workshop addresses anyone interested in Search solutions, the workshop aim is to be a light intro in Search engines and especially Apache Solr. Apache Solr is one of the two main open source search engines existing today and it’s also the base for the search functionalities implemented in several big data platforms ( e.g. Datastax, Cloudera). Thus, understanding Solr will help you not only in working with the Apache version but as well have a starting point in several platforms that use Solr as base for their search functionalities.

Big Data Architecture intro workshop

marcatanaLeave a comment

This workshop is addressed to anyone interested in Big Data and the overall architectural components required to build a data solution. We will use Apache Zeppelin for some data exploration but otherwise the workshop will be more a theoretical one – allowing enough time to overall understand which are the possible components and their role in a Big Data Architecture. We will not go in depth in the components/solutions but the aim is to understand the overall role of possible components in architecting a big data solution.

The scope of this workshop is to make the participants familiar with the Big Data architecture components and has as prerequisite the overall understanding of IT architectures.

Date: February 24th, 2018, 9:00 – 13:00

SQL on Hadoop hands on session, part 1: Hive and Impala intro

marcatanaLeave a comment

They say SQL is the english language of the Big Data World, since almost everybody understands/knows its syntax. The aim of this workshop is to explain in SQL what kind of queries can be run on HDFS (the storage component of the Hadoop environment) – for batch and interactive queries – and, out of the several solutions available, to address and run hands on exercises on Apache Hive and Apache Impala and discuss the general performance that can be obtained. We will also discuss different file formats that can be used in order to get the best performance out of Hive and Impala, besides the types of operations/analytics that can be performed on HDFS data.
