AlterTableMonitorRequest

public AlterTableMonitorRequest()

Constructs an AlterTableMonitorRequest object with default parameters.

AlterTableMonitorRequest

public AlterTableMonitorRequest(String topicId,
                                Map<String,String> monitorUpdatesMap,
                                Map<String,String> options)

Constructs an AlterTableMonitorRequest object with the specified parameters.

Parameters:

topicId - The topic ID returned by GPUdb.createTableMonitor.

monitorUpdatesMap - Map containing the properties of the table monitor to be updated. Error if empty.

• SCHEMA_NAME: Updates the schema name. If SCHEMA_NAME doesn't exist, an error will be thrown. If SCHEMA_NAME is empty, then the user's default schema will be used.
• MAX_CONSECUTIVE_FAILURES: Updates the maximum number of consecutive failures before suspending the stream. A value of '-1' to disables auto-suspend. This value is by rank and not overall.
• NOTIFICATIONS: Updates the state of the monitor. Supported values:
  • RESUME
  • SUSPEND
  The default value is an empty Map.

options - Optional parameters. The default value is an empty Map.
