John Davies ist Mitgründer und CTO des Unternehmens C24. In seiner Session In-Process or distributed? Performance or Scalability? auf der JAX 2016 diskutierte er die Frage, ob Skalierbarkeit oder Performance wichtiger ist. Im Interview mit JAXenter-Redakteurin Gabriela Motroc sprach er darüber, warum die Effizienz von Binärcode so viel besser als die von Java-Objekten ist, weshalb er Hadoop hasst und welche Probleme Spark mit sich bringt.
