Jeff Zhang commented on PIG-794:
--------------------------------
Attach the updated patch Avro_Strorage_3.patch ( I found one place can been
optimized)
The following is the latest experiment result (which shows AvroStorage is a
little better than InterStorage)
||Storage || Time spent on job_1 || Output size of job_1 ||
Mapper task number of job_2 || Time spent on job_2 || Total spent time on pig
script ||
|AvroStorage |3min 51 sec |7.96G |120 |17min 09 sec |21min 0 sec|
|InterStorage |4min 33 sec |9.55G |143 |17min 17 sec |21min 50 sec|
