Surviving SQS and building B-link Trees on S3As mentioned above, to bypass the severe latency of writing full data pages directly to S3, clients commit transactions by shipping small redo log records to SQS queues. Subsequently, clients act as checkpointers, asynchronously pulling these queued logs and applying the updates to their local copies before writing the newly materialized B-tree pages back to S3. This asynchronous log-shipping model means B-tree pages on S3 can be arbitrarily out-of-date compared to the real-time logs in SQS. Working on such stale state seems impossible, but the authors bound the staleness: writers (and probabilistically readers) run asynchronous checkpoints that pull batches of logs from SQS and apply them to S3, keeping the database consistent despite delays.

There are two main types of turntables: belt drive and direct drive. All of the models we tested for this guide are belt drive, which means there’s a thin belt that connects the platter to the motor to make the thing spin. Direct drive turntables are widely used by DJs and Technics was the first to make them. Here, the motor is directly under the platter and connected to it directly so the setup is less prone to wearing out. This is especially key when you’re doing things like scratching. Direct-drive turntables tend to be more expensive than their belt-driven counterparts.。关于这个话题，同城约会提供了深入分析
