Scott Carey commented on AVRO-989:
----------------------------------
Overall looks good, but there is a test failure.
Running org.apache.avro.tool.TestSpecificCompilerTool
Tests run: 3, Failures: 2, Errors: 0, Skipped: 0, Time elapsed: 0.708 sec <<<
FAILURE!
This fails because it is expecting the old output from the specific compiler.
All other tests passed.
> 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.
