    Summary of Creating multiple external content connectors of the same type

    ServiceNow AI Platform® allows administrators to create multiple external content connectors of the same type on a single instance. These connectors can crawl either different source systems or the same source system, with the option to have overlapping crawl locations. This flexibility enables comprehensive content retrieval from various or identical sources while managing indexing and user permissions effectively.

    Supported Configurations

    • Different source systems: Multiple connectors of the same type can crawl distinct source systems without overlap, preventing content duplication.
    • Same source system with distinct crawl scopes: Connectors crawl different sites within the same source system, avoiding duplicate content retrieval.
    • Same source system with overlapping crawl scopes: Connectors may have overlapping crawl sites, resulting in potential duplicate retrieval from those sites, but not from other distinct sites.

    Behavior Notes

    • All connectors of the same type feed their retrieved content into a single, shared indexed source.
    • During indexing, duplicate items retrieved by multiple connectors of the same type are deduplicated, ensuring only one copy appears in search results.
    • User permissions are managed individually per connector; each connector requires its own user permission crawl to populate security principals.
    • Crawl jobs for multiple connectors of the same type can run in parallel if system resources allow; otherwise, they execute sequentially.
    • The crawl limit of one million items applies separately to each connector, allowing substantial content retrieval per connector.

    Considerations for Parallel Execution

    • Parallel crawling of the same source system may increase request load, potentially triggering rate-limit issues on the source system.
    • Running multiple crawl jobs in parallel can cause contention on the shared indexed source, which may reduce the retrieval rate of connectors during parallel execution.

    Admins can create multiple external content connectors of the same type on a single ServiceNow AI Platform® instance. These connectors can crawl different source systems or the same source system. Connectors that crawl the same source system can include overlapping crawl locations.

    Supported configurations

    The system supports these configurations for multiple external content connectors of the same type running on the same ServiceNow AI Platform instance.
    Multiple external content connectors of the same type that crawl different source systems
    For example, one Microsoft SharePoint Online external content connector crawls sites 1A and 1B in source system 1, while a second Microsoft SharePoint Online external content connector crawls sites 2A and 2B in source system 2. The two external content connectors have no sites in common, so there's no duplication of retrieved content.
    Multiple external content connectors of the same type that crawl the same source system with distinct crawl scopes
    For example, one Microsoft SharePoint Online external content connector crawls sites 1A and 1B in source system 1, while a second Microsoft SharePoint Online external content connector crawls sites 1C and 1D in source system 1. The two external content connectors have no sites in common, so there's no duplication of retrieved content.
    Multiple external content connectors of the same type that crawl the same source system with overlapping crawl scopes
    For example, one Microsoft SharePoint Online external content connector crawls sites 1A and 1B in source system 1, while a second Microsoft SharePoint Online external content connector crawls sites 1B and 1C in source system 1. The two external content connectors have site 1B in common, so content from that site may be retrieved by both connectors. There's no duplication of retrieved content from the other sites.

    Behavior notes

    When you create multiple external content connectors of the same type on the same ServiceNow AI Platform instance, they behave as described in the following list.
    All external content connectors of the same type feed their retrieved content to the same indexed source
    In the previous examples, all content retrieved by either of the two Microsoft SharePoint Online external content connectors would be fed to the SharePoint Online indexed source.
    During indexing of crawled content, retrieved items are deduplicated across all external content connectors of the same type
    As an example, if two different Microsoft SharePoint Online external content connectors both retrieve the same file from the same site, only one copy of the retrieved file is indexed and appears in your search results.
    User permissions are specific to an individual external content connector, not shared between all external content connectors of the same type
    Admins need to run a separate user permission crawl for each external content connector of the same type. In the preceding examples, each Microsoft SharePoint Online external content connector needs its own user permission crawl. Running a user permission crawl for the first Microsoft SharePoint Online external content connector does not populate security principals for the second connector.
    The system executes crawl jobs for external content connectors of the same type in parallel if sufficient resources are available
    If sufficient resources for parallel execution aren't available, the system executes the crawl jobs sequentially instead.
    The crawl limit of one million items applies separately to each external content connector of the same type
    In the preceding examples, each individual Microsoft SharePoint Online external content connector can crawl up to one million items.

    Considerations for parallel execution

    When creating multiple external content connectors of the same type on the same ServiceNow AI Platform instance, bear the following considerations in mind.
    Increased request load on source system
    Creating multiple external content connectors that crawl the same source system in parallel can increase the rate at which requests are made to the source system. This may trigger rate-limit issues on the source system.
    Indexed source contention when running in parallel
    Running crawl jobs for multiple external content connectors of the same type in parallel can cause contention when they send retrieved content to their shared indexed source. This contention may reduce the connectors' retrieval rate when their crawl jobs are run in parallel.
