[jira] [Created] (AVRO-2090) Improve encode/decode time for
SpecificRecord using code generation
Raymie Stata created AVRO-2090:
----------------------------------
Summary: Improve encode/decode time for SpecificRecord using code generation
Key: AVRO-2090
URL: https://issues.apache.org/jira/browse/AVRO-2090
Project: Avro
Issue Type: Improvement
Components: java
Reporter: Raymie Stata
Compared to GenericRecords, SpecificRecords offer type-safety plus the performance of traditional getters/setters/instance variables. But these are only beneficial to Java code accessing those records. SpecificRecords inherit serialization and deserialization code from GenericRecords, which is dynamic and thus slow (in fact, benchmarks show that serialization and deserialization is _slower_ for SpecificRecord than for GenericRecord).
This patch extends record.vm to generate custom, higher-performance encoder and decoder functions for SpecificRecords. We've run a public benchmark showing that the new code reduces serialization time by 2/3 and deserialization time by close to 50%.
