Description

Write a Spark DataFrame to a tabular (typically, comma-separated) file.

Usage

spark_write_csv(
  x,
  path,
  header = TRUE,
  delimiter = ",",
  quote = "\"",
  escape = "\\",
  charset = "UTF-8",
  null_value = NULL,
  options = list(),
  mode = NULL,
  partition_by = NULL,
  ...
)

Arguments

x	A Spark DataFrame or dplyr operation
path	The path to the file. Needs to be accessible from the cluster. Supports the ‘⁠"hdfs://"⁠’, ‘⁠"s3a://"⁠’ and ‘⁠"file://"⁠’ protocols.
header	Should the first row of data be used as a header? Defaults to TRUE.
delimiter	The character used to delimit each column, defaults to ,.
quote	The character used as a quote. Defaults to ‘⁠'"'⁠’.
escape	The character used to escape other characters, defaults to \.
charset	The character set, defaults to "UTF-8".
null_value	The character to use for default values, defaults to NULL.
options	A list of strings with additional options.
mode	A character element. Specifies the behavior when data or table already exists. Supported values include: 'error', 'append', 'overwrite' and ignore. Notice that 'overwrite' will also change the column structure. For more details see also https://spark.apache.org/docs/latest/sql-programming-guide.html#save-modes for your version of Spark.
partition_by	A character vector. Partitions the output by the given columns on the file system.
...	Optional arguments; currently unused.
