I forgot the to_bytes function:
def pa_to_bytes(data_in):
debug_f = False
batch = pa.record_batch([data_in],names=['f0'])
if (debug_f):
print("len(batch)=",len(batch))
sink = pa.BufferOutputStream()
# print("len(sink)=",len(sink)) # sink has no length
with pa.ipc.new_stream(sink, batch.schema) as writer:
#for i in range(8*1024):
writer.write_batch(batch)
# end for
# end with
buf = sink.getvalue()
pa_bytes = buf.to_pybytes()
return pa_bytes
# end pa_to_bytes
