I want to pause on that for a moment, because it’s important. Composition lets us combine primitive CRDTs into more complex ones. When it’s time to merge, all the parent does is pass slices of incoming state to the appropriate child’s merge function. We can nest this process as many times as we want; each complex CRDT passing ever-smaller slices of state down to the next level, until we finally hit a primitive CRDT that performs the actual merge.
In Mongo, when using w: 1 in a write concern, the write operation is acknowledged after being successfully applied to the primary's instance memory. However, w: 1 alone does not guarantee durability unless combined with j: true (journaling). Running standalone Mongo, as we did in the tests, defaults to j: false. I have explicitly set it to true in the testing script to make write comparisons to Postgres objective. You can dive deeper into this here: https://www.mongodb.com/docs/manual/reference/write-concern/#acknowledgment-behavior and here: https://www.mongodb.com/docs/manual/core/journaling/. Unfortunately, docs are a bit convoluted about it
