Work Description: reuvenlax opened a new pull request #5723: [BEAM-4613]
Use ByteBuddy to generate a coder class for a specific Schema.
URL: https://github.com/apache/beam/pull/5723
Previously, RowCoder had to iterate over the schema to determine how
encode/decode Row objects. This PR adds functionality to dynamically generate a
Coder class per schema that hard codes the proper encoding strategy. Simple
microbenchmarks (not included in this PR) show that this new strategy is 30-40%
faster for moderate schemas, and the difference is expected to be larger for
complex schemas.
In addition, this PR allows RowCoder to bypass the validation steps when
building a Row, as it's assumed that these steps were performed before encoding
the Row.
