“村马”的“出圈”之路，藏着贵州乡村发展的巧思。三都有着千年水族端节赛马习俗。杨凯代表介绍，当地没有摒弃赛事原生的“村”味，而是在原有基础上融入新规则、重塑赛事体系，既保留水族赛马“无鞍骑行”的传统特色，又融入现代赛事运营理念，让这一民俗活动迅速成长为文旅“黑马”。
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.
