The "Avro/Glossary" page has been changed by JeffHammerbacher. http://wiki.apache.org/hadoop/Avro/Glossary?action=diff&rev1=4&rev2=5 -------------------------------------------------- === IO === - * '''Decoder''' - * '''Encoder''' + * '''Encoder'''/'''Decoder''': Avro specifies two different encodings: Binary and JSON. See http://hadoop.apache.org/avro/docs/current/spec.html#Encodings for the details of these encodings. + * '''block''': Array and Maps are encoded as a series of blocks, with a "count" long at the beginning of each block (and optionally "size"). Used for reading and writing data structures that don't fit into memory (maybe; not implemented yet). May also refer to the "blocks" in a file object container. * '''!DatumReader'''/'''!DatumWriter''' * '''!DataFileReader'''/'''!DataFileWriter'''
