Settings passed to a source when subscribing

SourceSubscriptionSettings contains all the information a source needs to intelligently handle bootstrap and subscription for a query, including the specific node and relation labels the query is interested in.

Fields

• source_id: ID of the source
• enable_bootstrap: Whether to request initial data
• query_id: ID of the subscribing query
• nodes: Set of node labels the query is interested in from this source
• relations: Set of relation labels the query is interested in from this source

Example

use drasi_lib::config::SourceSubscriptionSettings;
use std::collections::HashSet;

let settings = SourceSubscriptionSettings {
    source_id: "orders_db".to_string(),
    enable_bootstrap: true,
    query_id: "my-query".to_string(),
    nodes: ["Order", "Customer"].iter().map(|s| s.to_string()).collect(),
    relations: ["PLACED_BY"].iter().map(|s| s.to_string()).collect(),
};

Fields

source_id: String

enable_bootstrap: bool

query_id: String
