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)>), ...)).
spark_read_avro(
sc,
name = NULL,
path = name,
avro_schema = NULL,
ignore_extension = TRUE,
repartition = 0,
memory = TRUE,
overwrite = TRUE
)
sc |
A |
name |
The name to assign to the newly generated table. |
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 |
ignore_extension |
If enabled, all files with and without .avro extension
are loaded (default: |
repartition |
The number of partitions used to distribute the generated table. Use 0 (the default) to avoid partitioning. |
memory |
Boolean; should the data be loaded eagerly into memory? (That is, should the table be cached?) |
overwrite |
Boolean; overwrite the table with the given name if it already exists? |
