Queries (Json Schema Query Folder)
This folder under a JSON schema stores search queries whose results are then available to be used by the schema. Queries generate
JSON payloads from the results of bql or neql searches. For example, a query may include a report of overridden points, active
alarms, or history logs for a given point.

| Property | Value | Description |
|---|---|---|
| Query Interval | time | Defines how often the schema executes its queries, which determines how up-to-date exported data are when the schema uses
an Update Strategy of COV.
If multiple queries exist, each time the schema executes it runs each query in parallel. |
| Last Query Completed Timestamp | read-only (defaults to null) | Reports the time the last query completed. |
| Queries, queriesMaxExecutionTime (hidden property on the Queries folder) | time | Increases the amount of time granted to complete all queries on each cycle. Failure to complete within this time causes the schema generation to fail. |
