Storage

The Storage Task lets you create/update, retrieve, search for, and delete files. Use this to share data between Flow Executions or store details of a previous execution and access it on subsequent runs (think: Batch Jobs need to store last timestamp ran or last JourneyID processed).

Configuration

The storage task has four operations:

• Put Record
• Query By Key
• Query By Prefix
• Delete Record

Storage Task Configuration

Operation / Configuration	Description
Put Record	Create a short-lived file or update a file if the filename already exists.
Key	Name of file. All files created by the Storage Task exist in a single shared folder for the tenant.
Sensitivity	Files can be accessed from Flow Studio to allow for debugging / review provided your User has two new Integration Flow app permissions: “Persisted Storage Access” and “Persisted Storage Get”. It is expected that sometimes a file will contain sensitive data. For this we’ve created an separate permission “Persisted Storage Get Sensitive Record” to further restrict access. Options: - Sensitive - Not Sensitive
Time to Live (TTL)	All files created by Storage Task are temporary and will be deleted once the TTL expires to conserve space. Each time a file is updated (using the PUT operation with a filename of an existing file) the TTL will be extended. Options: - One Week - One Month
Content	Templated Input. This is the content of the file. Supports JSON & Text formats currently.
Query by Key	Returns the content of the matching file in full or partial. Throws an exception if no matching file is found.
Key	Name of file to retrieve
Partial Read	Indicates if full file should be read or partial. Following options determine how much data is read and from where in the file when partial reading.
Batch Size	Number of lines to read from the file. A line is denoted by CRLF or LF (Carriage Return \r + Line Feed \n) characters.
Start Byte Position	Location in file where to start reading. Start of file begins at Position 0, inspect task output to see where the previous partial read operation finished.
With Headers	Optionally includes headers as the first row with each subsequent partial read.
Query by Prefix	Returns a list of file names that match a prefix.
Prefix	Text to search.
Delete Record	Deletes the matching file. Throws an exception if not matching file is found.
Key	Name of file to retrieve

Task Output

Returns the output from the invoked flow that can be used in subsequent tasks.
