 | **delay** | The amount of time to delay the start of data processing for the window. The pipeline run is started after the expected execution time plus the amount of **delay**. The **delay** defines how long the trigger waits past the due time before triggering a new run. The **delay** doesn’t alter the window **startTime**. For example, a **delay** value of 00:10:00 implies a delay of 10 minutes. | Timespan<br/>(hh:mm:ss)  | A timespan value where the default is 00:00:00. | No |
 | **maxConcurrency** | The number of simultaneous trigger runs that are fired for windows that are ready. For example, to back fill hourly runs for yesterday results in 24 windows. If **maxConcurrency** = 10, trigger events are fired only for the first 10 windows (00:00-01:00 - 09:00-10:00). After the first 10 triggered pipeline runs are complete, trigger runs are fired for the next 10 windows (10:00-11:00 - 19:00-20:00). Continuing with this example of **maxConcurrency** = 10, if there are 10 windows ready, there are 10 total pipeline runs. If there's only 1 window ready, there's only 1 pipeline run. | Integer | An integer between 1 and 50. | Yes |
 | **retryPolicy: Count** | The number of retries before the pipeline run is marked as "Failed."  | Integer | An integer, where the default is 0 (no retries). | No |
-| **retryPolicy: intervalInSeconds** | The delay between retry attempts specified in seconds. | Integer | The number of seconds, where the default is 30. | No |
+| **retryPolicy: intervalInSeconds** | The delay between retry attempts specified in seconds. | Integer | The number of seconds, where the default is 30. The minimum value is 30. | No |
 | **dependsOn: type** | The type of TumblingWindowTriggerReference. Required if a dependency is set. | String |  "TumblingWindowTriggerDependencyReference", "SelfDependencyTumblingWindowTriggerReference" | No |
 | **dependsOn: size** | The size of the dependency tumbling window. | Timespan<br/>(hh:mm:ss)  | A positive timespan value where the default is the window size of the child trigger  | No |
 | **dependsOn: offset** | The offset of the dependency trigger. | Timespan<br/>(hh:mm:ss) |  A timespan value that must be negative in a self-dependency. If no value specified, the window is the same as the trigger itself. | Self-Dependency: Yes<br/>Other: No  |
