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

The iPad Air, the middle child in Apple’s tablet lineup, has been upgraded to the M4 chip with increased RAM and… Well, there’s not a whole lot else if I’m being honest. At the very least, the new iPad Air M4 models remain at the same price as the iPad Air M3, with the 11-inch version starting at $599 and the 13-inch at $799. I would give Apple more credit if it had increased the starting storage or added literally anything else.，这一点在爱思助手下载最新版本中也有详细论述
