Hallo, ich bin Redis (JUG Saxony Day 2016)

Caching? Verteile Sessions? Pub/Sub? 100.000 Requests pro Sekunde? Dies und viel mehr bietet Redis. Redis ist ein vielseitiger Open Source NoSQL Data Store der sich einer immer größeren Beliebtheit erfreut. Der Vortrag ist eine Einführung in Redis und veranschaulicht mit Hilfe von Code-Beispielen, wie Redis mit Spring Data, Hibernate OGM und plain Java verwendet werden kann.
