Use Arrow IPC serialization format for building data-frame-like
output to increase performance: The umwelt.info streaming endpoints
/search/all and /dataset/all now support Arrow
IPC in addition to ND-JSON. Using Arrow IPC, the output is returned as a
tibble.
Use column-selection API to reduce network traffic: The
umwelt.info streaming endpoints /search/all and
/dataset/all now support reducing the amount of transmitted
data by choosing which columns to serialize.
