Instance methods

gparquet_reader_properties_disable_buffered_stream

Disable buffered stream reading. This is the default.

unstable since: 26.0.0

gparquet_reader_properties_enable_buffered_stream

Enable buffered stream reading. To avoid pre-buffering whole column chunks, also call gparquet_reader_properties_set_pre_buffer() with FALSE. This does not impose a limit on the memory used by decoded data.

No description available.

unstable since: 26.0.0

gparquet_reader_properties_set_buffer_size

Set the buffered stream size. This does not enable buffered stream reading. Reads required for a data page may exceed this size.

unstable since: 26.0.0

gparquet_reader_properties_set_pre_buffer

Set whether to pre-buffer column chunks to coalesce reads. This is enabled by default to improve performance on high-latency filesystems. Set this to FALSE to use buffered streams without pre-buffering whole column chunks. This does not enable or disable buffered stream reading.
