spark_write_avro: Serialize a Spark DataFrame into Apache Avro format

In rstudio/sparklyr: R Interface to Apache Spark

Serialize a Spark DataFrame into Apache Avro format

Description

Notice this functionality requires the Spark connection sc to be instantiated with either an explicitly specified Spark version (i.e., spark_connect(..., version = <version>, packages = c("avro", <other package(s)>), ...)) or a specific version of Spark avro package to use (e.g., spark_connect(..., packages = c("org.apache.spark:spark-avro_2.12:3.0.0", <other package(s)>), ...)).

Usage

spark_write_avro(
  x,
  path,
  avro_schema = NULL,
  record_name = "topLevelRecord",
  record_namespace = "",
  compression = "snappy",
  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.
avro_schema	Optional Avro schema in JSON format
record_name	Optional top level record name in write result (default: "topLevelRecord")
record_namespace	Record namespace in write result (default: "")
compression	Compression codec to use (default: "snappy")
partition_by	A character vector. Partitions the output by the given columns on the file system.
