Add a proposal to expiry and cleanup artifacts generated by XTable #655
Description
Develop a proposal to manage artifacts generated by XTable, focusing on efficient expiry and cleanup of files generated by XTable for storage used by Target format and query performance.
XTable generates Commit Logs which are typically small in size. It will soon start generating Deletion Files which are expected to grow quickly and require more storage management.
Cleanup Policies could align artifact cleanup with the existing policies of the source table, or be implemented using specific configurations within XTable.
Potential topics to discuss include policy management, automated and custom cleanup mechanism, and monitoring and reporting.
