    GitHub V1 Connector Configuration Reference

    Table of Contents

    The GitHub connector retrieves data from GitHub repositories using the GitHub REST API.

    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.

    GitHub repository access needs authentication, in which case GitHub oAuth token Authentication will be used to perform GitHub requests. See the GitHub oAuth Authentication page for more information.

    The GitHub API service implements rate limiting. If you repeatedly crawl the commits in a large or old repository, this can trigger a temporary lockout. For this reason, Lucidworks recommends creating a separate GitHub user specifically for Fusion’s GitHub connector.


    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.


    description - string

    Optional description for this datasource.

    id - stringrequired

    Unique name for this datasource.

    >= 1 characters

    properties - Properties

    Datasource configuration properties

    chunkSize - integer

    The number of items to batch for each round of fetching. A higher value can make crawling faster, but memory usage is also increased. The default is 1.

    Default: 1

    commitAfterItems - integer

    Commit the crawlDB to disk after this many items have been received. A smaller number here will result in a slower crawl because of commits to disk being more frequent; conversely, a larger number here will cause a resumed job after a crash to need to recrawl more records.

    Default: 10000

    crawlDBType - string

    The type of crawl database to use, in-memory or on-disk.

    Default: on-disk

    Allowed values: in-memoryon-disk

    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.

    inlinks - boolean

    Keep track of incoming links. This negatively impacts performance and size of DB.

    Default: false

    Keep track of target URI-s that the current URI resolves to. This negatively impacts performance and size of DB.

    Default: com.lucidworks.connectors.db.impl.MapDbConnectorDb

    dedupe - boolean
