|Enables a secondary file system to store segment files
SECONDARY_DATA_DIRECTORY enables using a secondary file
system to store segment files. When to move the files is controlled by
PRIMARY_STORAGE_PERCENTAGE. Secondary storage is not
enabled by default. Note, that when using Docker, make sure to mount the
volume into the container as well.
See the page on Secondary Storage for more information.
These properties define the disk space limits at which LogScale will throttle itself to avoid filling the disks. When the primary disk cap is hit, LogScale will attempt to use the secondary storage instead. If both caps are hit, the affected LogScale node will pause processing of logs, and will avoid downloading segments from other nodes or buckets, until disk space is freed.
