Raymie Stata updated AVRO-2090: ------------------------------- Description: New implementation for generation of code for SpecificRecord that improves decoding by over 10% and encoding over 30% (more improvements are on the way). This feature is behind a feature flag ({{org.apache.avro.specific.use_custom_coders}}) and (for now) turned off by default. See [Getting Started (Java)|https://avro.apache.org/docs/current/gettingstartedjava.html#Beta+feature:+Generating+faster+code] for instructions. (A bit more info: 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.) was: New implementation for generation of code for SpecificRecord that improves decoding by over 10% and encoding over 30% (more improvements are on the way).
