db_dbfs_create: DBFS Create

Description

Open a stream to write to a file and returns a handle to this stream.

Usage

db_dbfs_create(
  path,
  overwrite = FALSE,
  host = db_host(),
  token = db_token(),
  perform_request = TRUE
)

Value

Handle which should subsequently be passed into db_dbfs_add_block()

and db_dbfs_close() when writing to a file through a stream.

Arguments

path

The path of the new file. The path should be the absolute DBFS path (for example /mnt/my-file.txt).

overwrite

Boolean, specifies whether to overwrite existing file or files.

host

Databricks workspace URL, defaults to calling db_host().

token

Databricks workspace token, defaults to calling db_token().

perform_request

If TRUE (default) the request is performed, if FALSE the httr2 request is returned without being performed.

Typical File Upload Flow

• Call create and get a handle via db_dbfs_create()

• Make one or more db_dbfs_add_block() calls with the handle you have

• Call db_dbfs_close() with the handle you have

Details

There is a 10 minute idle timeout on this handle. If a file or directory already exists on the given path and overwrite is set to FALSE, this call throws an exception with RESOURCE_ALREADY_EXISTS.
