Delete / DeletePath

Deletes a file or directory in given file system. Event metadata fields applicable for this action are as follows:

Field	Definition	Example	Default

With event metadata parameters as:

Parameter	Definition	Example	Default
pathPath	Json path in payload for file/directory path to delete	filePath	path

Rename / RenamePath

Renames a file or directory in given file system. Event metadata fields applicable for this action are as follows:

Field	Definition	Example	Default
domain	Name of the file system to use	imageFs	-

With event metadata parameters as:

Parameter	Definition	Example	Default
pathPath	Json path in payload for file/directory to rename	filePath	path
toPath	Json path in payload for new file/directory name	newPath	to

CopyFile

Copies or moves a file from one file system to another. Event metadata fields applicable for this action are as follows:

Field	Definition	Example	Default
domain	Name of the source file system to use	imageFs	-

With event metadata parameters as:

Parameter	Definition	Example	Default
target	Name of the target file system	cdnFs	-
pathPath	Json path in payload for file/directory to copy	filePath	path
toPath	Json path in payload for target file/directory	newPath	to
move	Whether file should be deleted from the source	true	false

Write / WriteFile

Writes contents to a single file or a set of files for a given file system:

Field	Definition	Example	Default
domain	Name of the file system to write to	dataLakeFs	-

With event metadata parameters as:

Parameter	Definition	Example	Default
pathPath	Json path in payload for directory path to list (from payload root)	parameters.id	path
mode	Type of file(s) to output (, )	sequence	single
prefix	Prefix to add to each file's name (for sequence mode output)	tracking/views	-
suffix	Suffix to add to each file's name (for sequence mode output)	_out.json	-
content	Event contents to write to file (for sequence mode, , or )	request	payload
overwrite	Whether to overwrite or append contents to output (for single mode output)	true	false

Example

Input

{
    "customerId": "customer-1",
    "productId": "product-1",
    "pageId": "product-detail"
}

Event Metadata

For sequence output mode, this handler uses a path writer, which is responsible for generating unique sequence file paths/names for wrting contents to. The writer can be configured by adding path.* parameters to file system definition.

Using "[uuid]" in prefix or suffix allows generation of globally unique paths and file names, as this entry is replaced with a UUID value generated.

Read / ReadFile

Reads and returns contents of a file (in a cachable manner):

Field	Definition	Example	Default
domain	Name of the file system to read from	contentsFs	-

With event metadata parameters as:

Parameter	Definition	Example	Default
pathPath	Json path in payload for directory path to list	id	path
format	Format of the file contents to retrieve (json,text)	json	text

Roles

syncFile

Uses pulse records to trigger delete, copy or move of files from one file system to another, based on handler role parameters.
