Subject [jira] [Updated] (AVRO-920) Reusable memory I/O objects
Date Mon, 10 Oct 2011 13:47:29 GMT

     [ https://issues.apache.org/jira/browse/AVRO-920?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Douglas Creager updated AVRO-920:
---------------------------------

    Attachment: 0001-Reusable-memory-I-O-objects.patch

Here's a patch that adds the following functions:

* {{avro_reader_reset}} is the analog to the existing {{avro_writer_reset}}
* {{avro_reader_memory_set_source}} causes a memory reader object to point at a new source
buffer
* {{avro_writer_memory_set_dest}} does the same for a memory writer object

> The {{avro_reader_t}} and {{avro_writer_t}} types handle the serialization of an Avro
value to/from a binary buffer.  Right now, you have to construct a new instance of these types
for every buffer you want to parse.  It would eliminate some memory allocation overhead if
the reader/writer instances could be reused across parses.
