Joseph Adler created AVRO-1241: ---------------------------------- Summary: improve trevni performance on string deserialization Key: AVRO-1241 URL: https://issues.apache.org/jira/browse/AVRO-1241 Project: Avro Issue Type: Improvement Components: java Affects Versions: 1.7.3 Reporter: Joseph Adler
I have been trying to implement a storage function for Apache Pig that writes data in Trevni format. I found that the storage function was very slow when reading whole records. I did some profiling (with Yourkit) and found that most of the CPU time was being spent in org.apache.trevni.InputBuffer$readString() (specifically in the String() method). I changed to java.nio.charset.CharsetDecoder.decode for deserialization and saw a big improvement. Changes are included in the patch. -- This message is automatically generated by JIRA.
