Fields

mode: Option<String>

Optional. When set, what mode of hive partitioning to use when reading data. The following modes are supported:

AUTO: automatically infer partition key name(s) and type(s). STRINGS: automatically infer partition key name(s). All types are strings. CUSTOM: partition key schema is encoded in the source URI prefix. Not all storage formats support hive partitioning. Requesting hive partitioning on an unsupported format will lead to an error. Currently supported formats are: JSON, CSV, ORC, Avro and Parquet.

source_uri_prefix: Option<String>

Optional. When hive partition detection is requested, a common prefix for all source uris must be required. The prefix must end immediately before the partition key encoding begins. For example, consider files following this data layout:

gs://bucket/path_to_table/dt=2019-06-01/country=USA/id=7/file.avro gs://bucket/path_to_table/dt=2019-05-31/country=CA/id=3/file.avro

When hive partitioning is requested with either AUTO or STRINGS detection, the common prefix can be either of gs://bucket/path_to_table or gs://bucket/path_to_table/.

CUSTOM detection requires encoding the partitioning schema immediately after the common prefix. For CUSTOM, any of

gs://bucket/path_to_table/{dt:DATE}/{country:STRING}/{id:INTEGER} gs://bucket/path_to_table/{dt:STRING}/{country:STRING}/{id:INTEGER} gs://bucket/path_to_table/{dt:DATE}/{country:STRING}/{id:STRING} would all be valid source URI prefixes.

require_partition_filter: Option<bool>

Optional. If set to true, queries over this table require a partition filter that can be used for partition elimination to be specified. Note that this field should only be true when creating a permanent external table or querying a temporary external table. Hive-partitioned loads with requirePartitionFilter explicitly set to true will fail.

fields: Vec<String>

Output only. For permanent external tables, this field is populated with the hive partition keys in the order they were inferred. The types of the partition keys can be deduced by checking the table schema (which will include the partition keys). Not every API will populate this field in the output. For example, Tables.Get will populate it, but Tables.List will not contain this field.

Trait Implementations

impl Clone for HivePartitioningOptions

fn clone(&self) -> HivePartitioningOptions

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for HivePartitioningOptions

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for HivePartitioningOptions

fn default() -> HivePartitioningOptions

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for HivePartitioningOptions

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq<HivePartitioningOptions> for HivePartitioningOptions

fn eq(&self, other: &HivePartitioningOptions) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for HivePartitioningOptions

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>where __S: Serializer,

Serialize this value into the given Serde serializer.
