Freshness
The StoreAll REST API provides a way for users to determine the freshness of data. This information
is comprised of the following dates:
• Freshness-Complete-Date: Until this date, all file system events have been ingested in the
Express Query database.
• Freshness-Recent-Date: This is the date of the most recent file system event ingested in the
Express Query database. File system events before this date can still be ingested. This date
will always be greater than or equal to the Freshness-Complete-Date.
These dates are returned in the HTTP header when HTTP GET is requested with the freshness
parameter. The returned values follow the full date format because the dates are returned in the
HTTP body JSON output (see Full Date Protocols). The only exception to this date format is when
Express Query is started, which makes the Offline Metadata Synchronizer run. In this situation,
the freshness dates are not available and the date value displays “n/a” until the synchronizer task
has finished (which may take hours to days to complete).

Truncated path names
HP recommends that the directory depth not exceed 100 (for example, a file named "a/b/c/file"
has a depth of 4) and that the path name length not exceed 2,548 characters (this includes the
"/" character, but excludes the mount point). When renaming files or folders, the 2,548 character
limit applies to the sum of all source and target paths.
