----------------------------------------
Summary: Optimize byte to Long/Integer conversions
Key: PIG-3259
URL: https://issues.apache.org/jira/browse/PIG-3259
Project: Pig
Issue Type: Bug
Affects Versions: 0.11, 0.11.1
Reporter: Prashant Kommireddi
Fix For: 0.12
These conversions can be performing better. If the input is not numeric
(1234abcd) the code calls Double.valueOf(String) regardless before finally
returning null. Any script that inadvertently (user's mistake or not) tries to
cast alpha-numeric column to int or long would result in many wasteful calls.
We can avoid this and only handle the cases we find the input to be a decimal
number (1234.56) and return null otherwise even before trying
Double.valueOf(String).
