Concourse tracks versions of your data by default. This way you can easily edit data without being afraid of losing anything since Concourse can easily revert to a previous state.
Pro Fully ACID compliant
ConcourseDB is known to have a very holistic approach to robustness and data integrity which is reflected by it being fully ACID compliant.
ConcourseDB has always been strict about making sure data is valid before allowing it into the database, and there is no way for a client to bypass those checks.
Pro Can easily query data from any point in the past
Because of its powerful version control capabilities, Concourse can easily and painlessly query and get data from any point in the past.
Cons
Con Not very popular
Since ConcourseDB is not a very popular solution among developers, it may be hard to find libraries or SDKs to easily integrate it into any platform with which you are developing.
