Introduction
Cloud Firestore is a flexible, scalable database for mobile, web, and server development from Firebase and Google Cloud Platform. Like Firebase Realtime Database, it keeps your data in sync across client apps through realtime listeners and offers offline support for mobile and web so you can build responsive apps that work regardless of network latency or Internet connectivity. With CDAP, Cloud Firestore users should be able to ETL their Firestore data into an analytics warehouse, as well as load application data from various sources into Firestore.
Use case(s)
- As an ETL developer, I would like to use application data stored in Firestore inside my data warehouse, so that I can use it for analytics purposes
- As an application developer, I would like data from various sources to be loaded into Firestore, so I can power my app with data and insights in various systems.
User Storie(s)
- As a user, I would like to create a pipeline using a Cloud Firestore source
- As a novice user, I want to be able to retrieve data from Firestore without specifying a query
- As an advanced user, I want to specify the query to retrieve data from Firestore
- As a application developer, I want to use a Cloud Firestore sink in CDAP to load insights from various sources into Firestore
- As an application developer, I want to add a document to Firestore using data from a relational database
- As an application developer, I want to specify the mappings from my source data to documents inside Firestore
