Raymie Stata updated AVRO-2090: ------------------------------- Attachment: customcoders.md Attaching a design document for (forthcoming) patch. > 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 > Attachments: customcoders.md > > > 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%. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
