How to create storage lifecycle rules in the different policies

Yong Zhang 0

I am trying to use java code to set the storage lifecycle policies to expire the data by prefixes. But I noticed it only allow to setting 100 rules under a policy https://learn.microsoft.com/en-us/azure/storage/blobs/lifecycle-management-overview?utm_source=chatgpt.com#lifecycle-management-policy-definition

So If I want to set more than 100 rules, how to achieve that by java code? If the policy name is not "default", it will show resource not found. What is the proper way to do this in java?

This document shows the value should always be "default"

Hi Yong Zhang,

To address the issue of setting more than 100 lifecycle rules in Azure Blob Storage using Java code, you need to work within the constraints of Azure's lifecycle management policies.

Azure Blob Storage lifecycle management policies allow a maximum of 100 rules per policy. This means you cannot exceed this limit within a single policy.

Review your rules and see if you can consolidate them. For example, if multiple rules have similar conditions and actions, you can combine them into a single rule with broader conditions.

Utilize prefixes and blob index tags to group similar blobs together. This can reduce the number of individual rules needed.

If you need more than 100 rules, consider creating multiple storage accounts, each with its own lifecycle management policy. This allows you to distribute the rules across different accounts.

Ensure that the policy name is always set to "default" when creating or updating lifecycle policies. If you attempt to use any other name, you'll receive a "resource not found" error.

Here’s an example of how to set a lifecycle policy in Java:

import com.azure.storage.blob.BlobServiceClient; import com.azure.storage.blob.BlobServiceClientBuilder; import com.azure.storage.blob.models.BlobServiceProperties; import com.azure.storage.blob.models.ManagementPolicy; import com.azure.storage.blob.models.ManagementPolicyRule; public class LifecycleManagement { public static void main(String[] args) { String connectionString = "<your_connection_string>"; BlobServiceClient blobServiceClient = new BlobServiceClientBuilder() .connectionString(connectionString) .buildClient(); // Define your rules here ManagementPolicyRule rule = new ManagementPolicyRule() .setName("rule1") .setEnabled(true) .setDefinition(/* your rule definition */); // Add rules to the policy ManagementPolicy policy = new ManagementPolicy() .setRules(Arrays.asList(rule)); // Set the policy blobServiceClient.setProperties(new BlobServiceProperties().setManagementPolicy(policy)); } }

By following these steps and utilizing the provided Java code example, you will be able to effectively manage your Azure Blob Storage lifecycle rules while adhering to the limitations.

Which client version do you use? I am using the 12.28.1 and the BlobServiceProperties doesn't have the setManagementPolicy method. Where can I find more examples?

Hi Yong Zhang,

The latest version of the Azure Storage Blob client library for Java is 12.29.0. If you're using version 12.28.1 and the BlobServiceProperties class doesn't have the setManagementPolicy method, you might want to update to the latest version.

If you're using version 12.28.1 of the Azure Storage Blob client library for Java and the BlobServiceProperties class doesn't have the setManagementPolicy method, you can use the ManagementPolicyClient class instead.
