Struct MetadataLocation 

Source 
pub struct MetadataLocation { /* private fields */ }
Expand description

Helper for parsing a location of the format: <metadata-dir>/<version>-<uuid>.metadata.json or with compression: <metadata-dir>/<version>-<uuid>.gz.metadata.json

<metadata-dir> is set to the write.metadata.path table property and it defaults to the <location>/metadata when the property is not set.

Implementations§

Source§

impl MetadataLocation

Source

pub fn try_new_with_metadata(metadata: &TableMetadata) -> Result<Self>

Creates a completely new metadata location starting at version 0, deriving the metadata directory and compression settings from the table metadata. Only used for creating a new table. For updates, see with_next_version and try_with_new_metadata.

Source

pub fn with_next_version(&self) -> Self

Creates a new metadata location for an updated metadata file. Increments the version number and generates a new UUID.

Source

pub fn try_with_new_metadata( &self, new_metadata: &TableMetadata, ) -> Result<Self>

Updates the metadata location with the metadata directory and compression settings from the new metadata.

Source

pub fn compression_codec(&self) -> CompressionCodec

Returns the compression codec used for this metadata location.
