spark_write_avro
Description
Serialize a Spark DataFrame into Apache Avro format. 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
| Arguments | Description |
|---|---|
| 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: ““) |
