Running `list keys` in Riak is a resource-intensive operation and can significantly affect the performance of the cluster, and it is not recommended for production use. - -### What are list keys operations in Riak? - -`List keys` operations in Riak involve iterating through all keys in a bucket to return a list of keys. The reason this is expensive in terms of resources is that Riak needs to traverse the entire dataset to generate a list of keys. As the dataset grows, the operation consumes more resources and takes longer to process the list, which can lead to reduced performance and scalability. - -### Troubleshoot the alert - -To address the `riakkv_list_keys_active` alert, follow these steps: - -1. Identify the processes and applications running `list keys` operations: - - Monitor your application logs and identify the processes or applications that are using these operations. You may need to enable additional logging to capture information related to `list keys`. - -2. Evaluate the necessity of `list keys` operations: - - Work with your development team and determine if there's a specific reason these operations are being used. If they are not necessary, consider replacing them with other, more efficient data retrieval techniques. - -3. Optimize data retrieval: - - If it is necessary to retrieve keys in your application, consider using an alternative strategy such as Secondary Indexes (2i) or implementing a custom solution tailored to your specific use case. - -4. Monitor the system: - - After making changes to your application, continue monitoring the active list key FSMs using Netdata to ensure that the number of active list keys operations is reduced. - -### Useful resources - -1.
