Struct QuerySessionContext 

#[non_exhaustive]
pub struct QuerySessionContext {
    pub query_id: Option<String>,
    pub query_start_time: Option<DateTime>,
    pub cluster_id: Option<String>,
    pub query_authorization_id: Option<String>,
    pub additional_context: Option<HashMap<String, String>>,
}

A structure used as a protocol between query engines and Lake Formation or Glue. Contains both a Lake Formation generated authorization identifier and information from the request's authorization context.

For more information about how to utilize QuerySessionContext, see Lake Formation workflow for application integration API operations in the developer guide.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

query_id: Option<String>

A unique identifier generated by the query engine for the query.

query_start_time: Option<DateTime>

A timestamp provided by the query engine for when the query started.

cluster_id: Option<String>

An identifier string for the consumer cluster.

query_authorization_id: Option<String>

A cryptographically generated query identifier generated by Glue or Lake Formation.

additional_context: Option<HashMap<String, String>>

An opaque string-string map passed by the query engine.
