V1 deprecation and removal notice
Starting in Fusion 5.12.0, all V1 connectors are deprecated. This means they are no longer being actively developed and will be removed in Fusion 5.13.0.
The replacement for this connector is in active development at this time and will be released at a future date.
If you are using this connector, you must migrate to the replacement connector or a supported alternative before upgrading to Fusion 5.13.0. We recommend migrating to the replacement connector as soon as possible to avoid any disruption to your workflows.

At the first connection, the Fusion MongoDB connector crawls the entire MongoDB and saves the checkpoint.
If Process oplog is not selected, when you restart the data source, the connector recrawls the entire MongoDB.
In this mode the connector does not support incremental recrawling, nor does it delete entries that are deleted from MongoDB.

When entering configuration values in the UI, use unescaped characters, such as \t for the tab character. When entering configuration values in the API, use escaped characters, such as \\t for the tab character.

Crawl a MongoDB database. For recrawls, the crawler can use the oplog in MongoDB to discover new content and updates to existing content (updated or removed documents). If a full re-synchronization is required, it can be done by de-selecting the oplog option and starting the crawl again.
description - string

id - stringrequired
Unique name for this datasource.
>= 1 characters
Match pattern: ^[a-zA-Z0-9_-]+$
pipeline - stringrequired
Name of an existing index pipeline for processing documents.

Datasource configuration properties
batch_size_solr_commit - integer
The number of documents every time solr_commit will be made.
Default: 1000

Default: true
customized_timestamp - integer
Customized timestamp in epoch format (e.g. 1557881001), it is used to overwrite the existing checkpoint in zookeeper, use it carefully. The checkpoint is overwritten as long as the oplog is enabled. This property is transient, it means: if you set a value and add/update the datasource, after the checkpoint is replaced, this property will be removed; you must refresh the UI manually
exclusiveMinimum: false
db - Connector DB
Type and properties for a ConnectorDB implementation to use with this datasource.
aliases - boolean
Keep track of original URI-s that resolved to the current URI. This negatively impacts performance and size of DB.
Default: false
inlinks - boolean
Keep track of incoming links. This negatively impacts performance and size of DB.
Default: false
inv_aliases - boolean

Default: false
initial_mapping - Initial field mapping
Provides mapping of fields before documents are sent to an index pipeline.
condition - string
