title: NoSql database for domain events
body: <p>We are planning to implement our own custom event-store to persist our domain events, for a huge banking system (millions of events). There are many types of NoSql data-stores, and each of them seems to respond to a specific use-case : document, columns-based, key-values, etc...</p>
  
  <p>We don't want to spend time managing indexes, and, in a second time, we would like to be able to feed our BI reporting system from that store.</p>
  
  <p>What kind of store do you think is the most appropriate for us ?</p>
