hive_partition {arrow}R Documentation

Construct Hive partitioning

Description

Hive partitioning embeds field names and values in path segments, such as "/year=2019/month=2/data.parquet".

Usage

hive_partition(..., null_fallback = NULL)

Arguments

...

named list of data types, passed to schema()

null_fallback

character to be used in place of missing values (NA or NULL) in partition columns. Default is "__HIVE_DEFAULT_PARTITION__", which is what Hive uses.

Details

Because fields are named in the path segments, order of fields passed to hive_partition() does not matter.

Value

A HivePartitioning, or a HivePartitioningFactory if calling hive_partition() with no arguments.

Examples

## Not run: 
hive_partition(year = int16(), month = int8())

## End(Not run)
