    • Methods, systems and apparatus, including computer program products, for propagating data across shards of a database system are described. According to one method, a first request that includes instructions to place a second request in a queue of a second shard is placed in a queue of a first database shard, and the change is committed to the records of the first shard. A queue processor polling the queue fetches and dispatches the first request, placing the second request in a queue of a second database shard. The second request includes instructions for making the change to the second shard. A queue processor of the second database shard polls the queue of the second database, fetches the second request, and dispatches it to make the change on the second database shard.
    • 描述了用于在数据库系统的分片上传播数据的方法,系统和装置,包括计算机程序产品。 根据一种方法,包括将第二请求放置在第二分片的队列中的指令的第一请求被放置在第一数据库分片的队列中,并且改变被提交到第一分片的记录。 轮询队列的队列处理器提取并分派第一个请求,将第二个请求放在第二个数据库分片的队列中。 第二个请求包括对第二个分片进行更改的指令。 第二数据库分片的队列处理器轮询第二个数据库的队列,获取第二个请求,并对其进行调度,以便对第二个数据库分片进行更改。
