Best Practices and Considerations in CRDTs

Drawing from our senior engineering knowledge as well as the real-world scenarios we discussed - Just like a good director planning their next movie, or an investor considering their next big move, we must also consider the best practices and important considerations while working with CRDTs.

Understand Your Use Case: Regardless of whether you're implementing a real-time editing tool like Google Docs (a scene from a multi-directional movie), or a distributed version system like Git (a complex financial instrument), understanding the situation helps select the right CRDT.

Expressive Power vs Efficiency: The CRDT you choose operates like a movie's cast. Some, like the OR-Set, have high expressibility (akin to an ensemble cast capable of complex narrative arcs). However, they can be resource-intensive (like having a high production cost). On the other hand, types like the G-Counter are efficient (a low-budget documentary maybe?) but offer less flexibility.

Network Latency: In distributed systems, accounting for network latency (akin to considering time differences when executing trades on a global scale or scheduling film shoots in different locations) is crucial. As CRDTs propagate updates regularly, this plays a significant role.

Garbage Collection: Similar to being mindful of trash production while on a world tour, garbage accumulation in CRDTS is something to be cautious about. For instance, in an OR-Set, tombstones tend to accumulate and need to be collected to avoid impacting performance.

Testing and Debugging: Just like previewing a movie before release or doing a dry-run of a financial model, testing and debugging your CRDTs for edge cases and potential issues is vital.
