[SECURITY] Fedora 27 Update: mongodb-3.4.11-4.fc27

Mongo (from “humongous”) is a high-performance, open source, schema-free document-oriented database. MongoDB is written in C++ and offers the follow ing features: * Collection oriented storage: easy storage of object/JSON-style data * Dynamic queries * Full index support, including on inner objects and embedded arrays * Query profiling * Replication and fail-over support * Efficient storage of binary data including large objects (e.g. photos and videos) * Auto-sharding for cloud-level scalability (currently in early alpha) * Commercial Support Available A key goal of MongoDB is to bridge the gap between key/value stores (which are fast and highly scalable) and traditional RDBMS systems (which are deep in functionality).
