Question:
Fiware: Data loss prevention
Description:
I’m working with the 0.27.0 version of context broker. I'm using the Cygnus generic enabler and I have established a MQTT agent that connects external devices to the context broker.
My major concern right now is how to prevent from data loss. I established the context broker and the Cygnus mongodb databases as replica sets, but that won't ensure that all data will be persisted into the databases. I have seen that Cygnus uses Apache flume. Looking at its configuration, the re-injection retries can be configured:
- Number of channel re-injection retries before a Flume event is definitely discarded (-1 means infinite retries)
cygnusagent.sources.http-source.handler.events_ttl = -1
¿It is a good idea to establish the retries value to -1? I have read about events re-injected in the channel forever.
¿What can be done to ensure that all the data will be persisted?
¿Is there any functionality into fiware ecosystem oriented to that purpose?
