从数据存储区将数据迁移到Google Cloud Firestore

[英]Migrating data to Google Cloud Firestore from Datastore

原文 2019-02-01 06:46:53 7 1 google-app-engine/ google-cloud-platform/ google-cloud-firestore/ google-cloud-datastore

I'm deciding to migrate the data of Google Cloud Datastore to Cloud Firestore. 我决定将Google Cloud Datastore的数据迁移到Cloud Firestore。 I've read all related documents & blogs, but didn't find the pricing comparison with Datastore to Firestore (though I've read all Firestore pricing & daily quota details). 我已经阅读了所有相关文档和博客，但是没有找到Datastore与Firestore的价格比较（尽管我已经阅读了所有Firestore的价格和每日配额详细信息）。

I want to know the disadvantages & drawbacks of Cloud Firestore, as our data is in large-scale. 我想知道Cloud Firestore的优缺点，因为我们的数据量很大。 I've gone through the document about choose mode ( https://cloud.google.com/datastore/docs/firestore-or-datastore ). 我已经阅读了有关选择模式的文档（ https://cloud.google.com/datastore/docs/firestore-or-datastore ）。 Is it safe to migrate all data to Cloud Firestore in Native Mode directly or to use Firestore in Datastore mode? 在本地模式下直接将所有数据迁移到Cloud Firestore还是在数据存储模式下使用Firestore安全吗？

Thanks in advance. 提前致谢。

Datastore to Firestore migration 数据存储到Firestore的迁移

As for the migration, it is 100% safe to migrate your Datastore app to Firestore in Datastore mode, but if you'd like to use Firestore in native mode you'd need to upgrade your application and perform manual data migration. 至于迁移，将您的Datastore应用程序以Datastore模式迁移到Firestore是100％安全的，但是如果您想以纯模式使用Firestore，则需要升级应用程序并执行手动数据迁移。

Just a couple of weeks ago, I have migrated one of our apps from Datastore to Firestore in Datastore mode, copying all the data with the export and import APIs . 就在几周前，我已将其中一个应用程序从Datastore迁移到了Datastore模式的Firestore，并使用export和import API复制了所有数据。
