---------------------------------------------
[~maropu] added some benchmark results in
[https://github.com/apache/spark/pull/29366]. For Avro, with a couple of
benchmarks I am proposing to add in SPARK-32531 (PR:
[https://github.com/apache/spark/pull/29352]) I get the following on master
branch:
*Before:*
Nested Struct 75s average
Array of Structs 34s average
*After:*
Nested Struct 49s average
Array of Structs 19s average

> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 3.0.0
> Reporter: Muhammad Samir Khan
> Priority: Major
>
> Two constructors in SpecificInternalRow can be made faster by using while
> loops instead of maps. This was originally noticed while working on
> SPARK-32532 and SPARK-32533 and will have impacts on performance of reading
> ORC and Avro files. Profiled the change using added benchmarks in SPARK-32531
> for nested and array'd structs.
