Performances

Here is some benchmarks done on my machine (macbook pro with 16 GO of ram and a core I7 3,5 GHz)

InMemory with db

Izanami run with :

izanami-server/target/universal/stage/bin/izanami  \
  -Dizanami.db.default=InMemoryWithDb \
  -Dizanami.db.inMemoryWithDb.db=Redis \
  -Dizanami.events.store=Kafka \
  -Dizanami.apikey.initialize.clientId=xxxx \
  -Dizanami.apikey.initialize.clientSecret=xxxx \
  -Dizanami.features.db.import=/Users/alexandredelegue/opun/izanami/izanami-benchmarks/data/features.ndjson \
  -Dlogger.file=/Users/alexandredelegue/opun/izanami/izanami-server/conf/prod-logger.xml
