DynamoDB delete table complete status - amazon-web-services

Question

I am deleting a table in DynamoDB using the following Javascript in Node.
var params = {
TableName : "MyTable"
};
dynamodb.deleteTable(params, function(err, data) {
// Not really done yet...!
});
I need to know when the table has actually been deleted. The callback doesn't indicate this, as it is still in the deleting process when this is called. Is there a way to know when the delete has completed?

The waitFor API can be used to check for the non-existence of table.
Waits for the tableNotExists state by periodically calling the
underlying DynamoDB.describeTable() operation every 20 seconds (at
most 25 times).
Sample code to delete the table and check for the non-existence of table using waitFor API:-
var AWS = require("aws-sdk");
AWS.config.update({
region : "us-west-2",
endpoint : "http://localhost:8000"
});
var dynamodb = new AWS.DynamoDB();
var params = {
TableName : "country"
};
var paramsWaitFor = {
TableName : 'country' /* required */
};
function waitForTableNotExists() {
dynamodb.waitFor('tableNotExists', paramsWaitFor, function(waitForErr,
waitForData) {
if (waitForErr) {
console.log(waitForErr, waitForErr.stack); // an error occurred
} else {
console.log('Deleted ====>', JSON.stringify(waitForData, null, 2));
}
});
}
dynamodb.deleteTable(params, function(err, data) {
if (err) {
console.error("Unable to delete table. Error JSON:", JSON.stringify(
err, null, 2));
} else {
console.log("Deleted table. Table description JSON:", JSON.stringify(
data, null, 2));
waitForTableNotExists();
}
});
