.Multisite sync logging can now use FIFO to offload logging to RADOS data objects Previously, multisite metadata and data logging configurations used OMAP data logs. With this release, FIFO data logging is available. To use FIFO with green field deployments, set the config option rgw_default_data_log_backing to fifo. NOTE: Configuration values are case-sensitive. Use `fifo` in lowercase to set config options. To change the data log backing that sites use, use the command `radosgw-admin --log-type fifo datalog type`.
