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 (v7.6.3#76005)
