About the report
Opening meeting Andrei Kogun represents the speaker and recalls the upcoming conferences that will be held in St. Petersburg:
TechTrain 2018 (September 1-2) and
Joker 2018 (October 19-20).

The first part of the meeting before the break was devoted to
Apache Spark ,
the examples shown are written in
Scala . The data on the Titanic was used as a data set. Narrated - enhanced and improved version of the
report from JPoint 2018 .

The second part demonstrated
Apache Ignite capabilities on the same dataset.
The demonstration
examples are written in
Java . Considering the authorship of Alexei in a significant part of
Apache Ignite ML , his comments, comments and answers to questions were especially valuable.

Surprisingly prepared audience at the last meeting - a significant part of the audience uses
Apache Ignite . Questions and answers to them were interesting both to the speaker and to other listeners.

Photos from the meeting will soon appear
here . The video will be available on
YouTube (with the announcement on
VK and
Google+ ). You can
