对于关注Surprise的读者来说,掌握以下几个核心要点将有助于更全面地理解当前局势。
首先,Going through them briefly: this is not a distributed system and it has a very hard limit on scalability or availability. You can deploy a “SpacetimeDB cluster”, meaning a primary instance and several followers with eventually consistent replication (emphasis on eventually consistent; the WAL is eventually consistent, the replication is too, there’s a lot of margin for things to go wrong here), but your whole system is bottlenecked by the CPU and RAM capacity of the machine where your main SpacetimeDB instance is deployed. You need enough CPU for your database to execute all the queries, but also for your whole application to execute all its application logic, as again the application lives inside the database. You need enough RAM to fit all your database’s data in-memory. SpacetimeDB is not disk-backed at all; it just flushes a WAL to disk (and periodically, snapshots that make recovering from the WAL quicker on restarts). If your dataset grows larger than RAM, your database (and your application, which are the same thing) will fail over. The only option for scalability here is vertical: buying a bigger machine to run your database.

此外,Last week's giveaway raised a few issues. First, the New World copies were all taken before all of the emails went out, so a lot of people did not even get a chance to try for a book. Second, due to a Leanpub bug the Europe coupon scheduled for 10 AM UTC actually activated at 10 AM my time, which was early evening for Europe. Third, everybody in the APAC region got left out.
