Hi, as an action point from last integration meeting (http://ircbot.wl.linuxfoundation.org/meetings/onap-int/2019/onap-int.2019-03-27-13.00.html), I took the point to initiate a thread on cassandra usage in ONAP.
Please note that I am not an expert, I added some experts in copy of the mail. My understanding is that we have today several cassandra databases (aai, music and portal) we have 3 nodes for music and aai and 1 single node for the portal. onap-aai-aai-cassandra-0 1/1 Running 0 24d onap-aai-aai-cassandra-1 1/1 Running 0 44d onap-aai-aai-cassandra-2 1/1 Running 0 18d onap-oof-music-cassandra-0 1/1 Running 0 44d onap-oof-music-cassandra-1 1/1 Running 0 44d onap-oof-music-cassandra-2 1/1 Running 0 44d onap-portal-portal-cassandra-5c66f77c5b-xf2c7 1/1 Running 0 20d I am a bit puzzled by the choice of cassandra DB as a mono node Database for a simple portal. As far as I understood, there is a current task in Onap installer project to put in place a single cassandra database that could be used by the different projects to converge at the end to 1 cassandra database. For the moment, my understanding is that the installation of cassandra cluster is done without really considering the specificities of cassandra. Typically the 3 nodes for aai are deployed according to k8s scheduler rules independently from any hardware constraints/placement requirements. My colleagues are currently finalizing the development of a cassandra operator for k8s that could be useful to ensure that the HA nature of cassandra remains HA even in virtual environment. It would make sense to consider such operator for the target cassandra. They are about to publish the operator. They also planned to initiate some work on multi-site clustering for Cassandra. /Morgan _________________________________________________________________________________________________________________________ Ce message et ses pieces jointes peuvent contenir des informations confidentielles ou privilegiees et ne doivent donc pas etre diffuses, exploites ou copies sans autorisation.
