Java: Improve Builder performance in Specific API
--------------------------------------------------
Key: AVRO-989
URL: https://issues.apache.org/jira/browse/AVRO-989
Project: Avro
Issue Type: Improvement
Components: java
Reporter: Scott Carey
The Specific API generates Builder objects for each record. This builder uses
a boolean[] to store flags for each field to indicate whether the field is set
or not.
This is not space efficient, a boolean[] takes 16 bytes plus one byte per
field, rounded up to the nearest 8 byte interval.
This can be improved on by using BitSet for large records, and bitmasks on an
int for records with less than 32 fields.
