ARR does not have a standardized meaning and is therefore unlikely to be comparable to similarly titled measures presented by other companies. ARR should be viewed independently of revenue and is not intended to be combined with or to replace that item Average rate of growth over a period of time Churn refers to a reduction of ARR that was present on day 1 of a fiscal period and DECREASES during the period Logos refers to clients and new logos means new clients The company's open source software is code that is designed to be publicly accessible-anyone can see, modify, and distribute the code as they see fit ● MariaDB 44
