Wait for Operations | Ruby API Client V1 (Deprecated)

This version of the Ruby API client has been deprecated in favor of the latest version of the Ruby API client.

Required API Key: any key with the addObject ACL

Method signature

index.wait_task(Integer taskID)

See code examples

About this method

Wait for a task to complete before executing the next line of code, to synchronize index updates.

All write operations in Algolia are asynchronous by design.

It means that when you add or update an object to your index, our servers will reply to your request with a taskID as soon as they understood the write operation. The actual insert and indexing will be done after replying to your code. You can wait for a task to complete by using the `taskID’ and this method.

Check out our full discussion about asynchronous methods.

If you want to ensure multiple objects have been indexed, you need to check all taskIDs.
