Can you append data to an existing Avro data file? -

it seems there isn't way append info existing avro serialized file. i'd have multiple processes writing single avro file, looks each time open it, start on scratch. don't want read in info , write out again.

using ruby illustration code have tried "ab" , "ab+" various settings, no joy.

file = file.open('data.avr', 'wb') schema = avro::schema.parse(schema) author = avro::io::datumwriter.new(schema) dw = avro::datafile::writer.new(file, writer, schema) dw << {"username" => "john", "age" => 25, "verified" => true} dw << {"username" => "ryan", "age" => 23, "verified" => false} dw.close

don't pass schema append file

avro

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
