pub struct ArrowWriterBuilder<W> { /* private fields */ }
Expand description
Construct an ArrowWriter
to encode RecordBatch
es into a single
ORC file.
Implementations§
Source§impl<W: Write> ArrowWriterBuilder<W>
impl<W: Write> ArrowWriterBuilder<W>
Sourcepub fn new(writer: W, schema: SchemaRef) -> Self
pub fn new(writer: W, schema: SchemaRef) -> Self
Create a new ArrowWriterBuilder
, which will write an ORC file to
the provided writer, with the expected Arrow schema.
Sourcepub fn with_batch_size(self, batch_size: usize) -> Self
pub fn with_batch_size(self, batch_size: usize) -> Self
Batch size controls the encoding behaviour, where batch_size
values
are encoded at a time. Default is 1024
.
Sourcepub fn with_stripe_byte_size(self, stripe_byte_size: usize) -> Self
pub fn with_stripe_byte_size(self, stripe_byte_size: usize) -> Self
The approximate size of stripes. Default is 64MiB
.
Sourcepub fn try_build(self) -> Result<ArrowWriter<W>>
pub fn try_build(self) -> Result<ArrowWriter<W>>
Construct an ArrowWriter
ready to encode RecordBatch
es into
an ORC file.
