MongoDB

MongoDB is a NoSQL database that stores JSON-like documents.

Connection Properties

The config section in a YAML file includes the following properties:

connectorname: MongoDB
    config:
      connection_url: mongodb://dbuser:passwd@host:port
      database: databasenmae
    select:
      - tablename

Here are the typical ways to configure MongoDB and their connection URLs:

Name Description Connection URL Example
Local Installation Install on Windows, macOS, Linux using official packages. mongodb://dbuser:passwd@host.or.ip:27017
Docker Deploy using the MongoDB Docker image. mongodb://dbuser:passwd@docker.host:27017
MongoDB Atlas MongoDB’s managed service on AWS, Azure, and Google Cloud. mongodb+srv://dbuser:passwd@cluster.mongodb.net
Managed Cloud AWS DocumentDB, Azure Cosmos DB, and others offer MongoDB as a managed database. mongodb://dbuser:passwd@managed.cloud:27017
Configuration Tools Use Ansible, Chef, or Puppet for automation of setup and configuration. mongodb://dbuser:passwd@config.tool:27017
Replica Set Set up for high availability with data replication across multiple MongoDB instances. mongodb://dbuser:passwd@replica.set:27017
Sharded Cluster Scalable distribution of datasets across multiple MongoDB instances. mongodb://dbuser:passwd@shard.cluster:27017
Kubernetes Deploy on Kubernetes using Helm charts or operators. mongodb://dbuser:passwd@k8s.cluster:27017
Manual Tarball Install directly from the official MongoDB tarball, typically on Linux. mongodb://dbuser:passwd@tarball.host:27017

Metadata Properties

In the metadata section, define the mode of data refresh. There are two modes: INCREMENTAL and FULL_TABLE. It supports datetime and Unix format.

INCREMENTAL

This mode fetches data from the date column mentioned in the replication key from the start date as mentioned in the replication value. Once it is scheduled, the replication value is updated automatically from the imported data.

metadata:
  TableName:
    replication_method: INCREMENTAL
    replication_key: Column name
    replication_value: column value that data starts from
    timezone: UNIX/UTC

FULL_TABLE

This mode fetches data from the date column mentioned in the replication key from the start date as mentioned in the replication value. Once it is scheduled, the replication value is updated based on the interval_type and interval_value from the imported data. For ex set interval_type as ‘year’ and intervalue value as ‘1’.In first schedule, will fetch the record from Jan 1, 2000 to Dec 31, 2000. In next schedule, will fetch the record from Jan 1, 2001 to Dec 31, 2001 and so on.


metadata:
  TableName:
    replication_method: FULL_TABLE
    replication_key: Column name
    replication_value: column value that data starts from
    interval_type: days/hours/minutes/year/month
    interval_value: integer value to add in interval type
    timezone: UNIX/UTC
