Avro defines a standard sort order for data. This permitsdata written by one system to be efficiently sorted by anothersystem. This can be an important optimization, as sort ordercomparisons are sometimes the most frequent per-objectoperation. Note also that Avro binary-encoded data can beefficiently ordered without deserializing it to objects.Data items may only be compared if they have identicalschemas. Pairwise comparisons are implemented recursivelywith a depth-first, left-to-right traversal of the schema.The first mismatch encountered determines the order of theitems.Two items with the same schema are compared according to thefollowing rules. null data is always equal. boolean data is ordered with false before true.
int, long, floatand double data is ordered by ascending numericvalue. bytes and fixed data arecompared lexicographically by unsigned 8-bit values. string data is compared lexicographically byUnicode code point. Note that since UTF-8 is used as thebinary encoding for strings, sorting of bytes and stringbinary data is identical. array data is compared lexicographically byelement. enum data is ordered by the symbol's positionin the enum schema. For example, an enum whose symbols are'z', 'a' would sort 'z' valuesbefore 'a' values.
union data is first ordered by the branchwithin the union, and, within that, by the type of thebranch. For example, an 'int', 'string'union would order all int values before all string values,with the ints and strings themselves ordered as definedabove. record data is ordered lexicographically byfield. If a field specifies that its order is:. 'ascending', then the order of its valuesis unaltered.
'descending', then the order of its valuesis reversed. 'ignore', then its values are ignoredwhen sorting. map data may not be compared. It is an errorto attempt to compare data containing maps unless those mapsare in an 'order':'ignore' record field.Object Container Files. A reader of Avro data, whether from an RPC or a file, canalways parse that data because its schema is provided. Butthat schema may not be exactly the schema that was expected.For example, if the data was written with a different versionof the software than it is read, then records may have hadfields added or removed. This section specifies how suchschema differences should be resolved.We call the schema used to write the data asthe writer's schema, and the schema that theapplication expects the reader's schema.
