Waiter for secondary indexes

[thomaswitt]

Describe the feature

When creating secondary indexes, DynamoDB can take a significant random time, even on an empty database. On one hash_key only index (no range key) I am waiting for about 2-3 minutes until it exits the backfilling state.

When you want to create data in a migration which depends on the new index, this is bad.

For creating a table, there's a handy Waiter in the Gem, but that only works on table_exists and table_not_exists.

When using the AWS CLI, I can get the index status:

. $ aws dynamodb describe-table --table-name MYAPP_production|jq '.Table.GlobalSecondaryIndexes[] | {IndexName, IndexStatus}'
{
  "IndexName": "user_email_gsi",
  "IndexStatus": "ACTIVE"
}

It would be great if that waiter would be available natively in the SDK.

Use Case

Creating data which depends on the existance of a new secondary index.

Thanks for the feature request. This unfortunately is an upstream request to the dynamodb team who owns the modeling which includes waiters. I can't guarantee delivery or timeline of these.
