firebase - 同一触发器的多个云函数会导致问题吗？ #AskFirebase

Question

云函数是否应该针对每个触发器进行整合，或者是否可以为同一触发器编写多个函数？特别是，如果我正在阅读内部文档...是否会对性能或计费产生重大影响？

// Example: multiple onWrite functions triggered by the same Firestore doc path
functions.firestore.document('myCollection/{itemId}').onWrite((change, context) => {
   // do one complex thing, potentially reading/writing data
}

functions.firestore.document('myCollection/{itemId}').onWrite((change, context) => {
   // do another complex thing, potentially reading/writing the same or different data
}

或者...

// Example: one trigger and a monolithic function handling everything...
functions.firestore.document('myCollection/{itemId}').onWrite(async (change, context) => {
   const otherDataSnapshot = await admin.firestore().ref('myPath').once('value').then();
   this.doOneComplexThing(change, context, otherDataSnapshot);
   this.doAnotherComplexThing(change, context, otherDataSnapshot);
}

const doOneComplexThing = (change, context, otherDataSnapshot) => {
   // do one complex thing
}

const doAnotherComplexThing = (change, context, otherDataSnapshot) => {
   // do that other complex thing
}

如果您有两个函数触发器而不是一个，那么您将需要为每个 onWrite 的两次调用付费，而不仅仅是一次。它总是会更贵。拆分它可能有充分的理由，值得拆分，因此您必须根据您的具体情况做出决定。
