Let’s embark on this journey together to understand how you can efficiently handle the lifecycle of your object storage data, thus optimizing costs and time.
Understanding Object Lifecycle Management
Object lifecycle management empowers users to automate archiving and deletion processes, effectively controlling the lifecycle of their stored data. By defining rules, users can automate actions such as moving data to infrequent access tiers, archiving, or deleting objects based on predetermined criteria.
Supported Resources and Rules
OCI supports managing various resources including objects, object versions, as well as uncommitted or failed multipart uploads. Rules can be specified with object name prefixes and pattern matching conditions to precisely target specific sets of objects. It’s important to note that deletion rules take precedence over rules for moving objects to different storage tiers.
Limitations and Considerations
Auto-tiering limitations should be considered when creating rules, ensuring that objects are appropriately managed. Additionally, there’s a cap of 1,000 lifecycle rules per bucket. While lifecycle policies can be applied to archive storage buckets, only delete rules are supported in this scenario.
Handling Pre-existing Data
Lifecycle policies apply retroactively to data uploaded before the policy’s creation. For instance, objects meeting the criteria specified in a newly implemented policy will be identified for the corresponding actions immediately.
Object Name Filtering
OCI provides two types of object name filters: prefix matching and pattern matching. Prefix matching involves exact matches of the left-most characters of object names, while pattern matching extends to wildcard characters, offering more flexible filtering options.
Precedence of Rules
During the evaluation of object name filters, precedence is given to pattern exclusions, followed by pattern inclusions, and finally prefix inclusions. Understanding this hierarchy ensures accurate application of lifecycle policies.
Supported Options in Lifecycle Policies
Lifecycle policy rules offer several options, including moving or deleting all objects in a bucket, managing objects based on specified object name filters, and handling uncommitted or failed multipart uploads. Users can also create rules for managing object versions, including both previous and latest versions, with the ability to specify object name filters.
Practical Example
Consider a scenario where standard tier objects are automatically moved to the archive tier 30 days after creation or last update. After 180 days in the archive tier, these objects are then automatically deleted. Additionally, a separate rule can be established to delete uncommitted or failed multipart uploads after five days.
By effectively utilizing OCI’s object lifecycle management features, users can streamline data management processes, optimize storage costs, and ensure efficient utilization of resources.
