ACID transactions are a key capability for business critical transactional systems, specifically around commerce processing. No other database has both the power of NoSQL and cross collection ACID transaction support. This combination will make it easy for developers to write mission critical applications leveraging the power of MongoDB"Dharmesh Panchmatia, Director of E-commerce, Cisco Systems
WiredTiger timestamps: enforcing correctness in operation ordering across the distributed storage layer. Hear from Dr. Michael Cahill, Director of Engineering for storage at MongoDB.
Local snapshot reads: allowing you to read from a single, consistent point in time across multiple network operations in a transaction. Hear from Tess Avitabile, MongoDB Lead Engineer on Replication.
Logical sessions: coordinating operations across a distributed cluster, presented by Jason Carey, Lead Engineer for platforms at MongoDB.
Global logical clock: establishing a global snapshot of data across a distributed cluster for transactional snapshot isolation. Hear from Misha Tyulenev, Staff Software Engineer for sharding at MongoDB.
Safe secondary reads: providing consistent reads against secondary replica set members, even while data is being rebalanced across a cluster. Hear from Dianna Hohensee, MongoDB software server engineer.
Retryable writes: allowing the MongoDB drivers to automatically retry transactions in the event of transient network errors or primary replica elections, while the server enforces exactly-once, all-or-nothing semantics. Learn more from Randolf Tan, senior software engineer at MongoDB.
