----------------------------------
Summary: Suggested optimization for Utf8.length()
Key: AVRO-1074
URL: https://issues.apache.org/jira/browse/AVRO-1074
Project: Avro
Issue Type: Improvement
Components: java
Affects Versions: 1.6.3
Reporter: Hernan Otero
Fix For: 1.7.0
Wanted to suggest a small optimization. It is quite common for applications to
do a quick check (along with null-ness) for 0-length of string-typed fields.
Today's Utf8.length() implementation is:
{code}return toString().length;{code}
I believe this could easily get optimized to return this instead:
{code}return length == 0 ? 0 : toString().length();{code}
Thus avoiding the need to create the string representation for this common use
case (and scenario).
