Can you suggest a better approach for deleting configuration objects that would be faster than querying them individually?: The uninstall uses a technique of deleting configuration and syncing triggers to remove the triggers first so it can drop sym tables. It deletes configuration by querying all of the configuration objects (trigger routers, routers, group links, etc) and removing each one. The problem is that the query uses a select with all the columns known in the current version, which doesn't work on an older database. Change the approach to just delete all rows from configuration tables instead of querying them, which will be faster anyway.

You could also consider using batch processing to delete configuration objects in larger groups, rather than individually. This would reduce the number of queries made and increase the speed of the deletion process. Additionally, you could use multi-threading or parallel processing to further increase the speed of the deletion process. Finally, you could consider creating an index on the configuration table to speed up the query process, allowing for faster deletion.

Can you please implement the suggested changes in the code and let me know if there are any issues that need to be addressed?

Sure, here's an example implementation for deleting all rows from the configuration tables instead of querying them individually:

```
// Function to delete all rows from configuration tables
function deleteConfiguration() {
  var configTables = ["trigger_routers", "routers", "group_links"]; // Add more tables as needed
  var db = // Get database object

  for (var I = 0; I < configTables.length; i++) {
    var table = configTables[i];
    var stmt = db.createStatement("DELETE FROM " + table);

    try {
      stmt.execute();
    } catch (e) {
      // Handle any errors
      console.error("Error deleting rows from " + table + ": " + e);
    } finally {
      stmt.finalize();
    }
  }
}

// Call function to delete configuration
deleteConfiguration();
```

This implementation uses a `for` loop to iterate through an array of table names and deletes all rows from each table using a SQL `DELETE` statement. Note that you'll need to replace `db` with your actual database object and add any additional configuration tables that need to be deleted. As for the indexing suggestion, you could create an index on the configuration tables to speed up queries. Here's an example implementation for creating an index:

```
// Function to create an index on the configuration tables
function createIndex() {
  var configTables = ["trigger_routers", "routers", "group_links"]; // Add more tables as needed
  var db = // Get database object

  for (var I = 0; I < configTables.length; i++) {
    var table = configTables[i];
    var stmt = db.createStatement("CREATE INDEX IF NOT EXISTS " + table + "_idx ON " + table + " (column1, column2, ...)");

    try {
      stmt.execute();
    } catch (e) {
      // Handle any errors
      console.error("Error creating index on " + table + ": " + e);
    } finally {
      stmt.finalize();
    }
  }
}

// Call function to create an index
createIndex();
```

This implementation creates an index on each configuration table using a SQL `CREATE INDEX` statement. Replace `db` with your actual database object and add any additional columns that should be indexed. Note that using indexing can improve query performance, but be careful not to create too many indexes, as this can slow down insert and update operations.
