Subject [jira] [Commented] (AVRO-1006) Fingerprints for Avro Schemas
Date Sat, 03 Mar 2012 00:29:59 GMT

    [ https://issues.apache.org/jira/browse/AVRO-1006?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13221386#comment-13221386
] 

Doug Cutting commented on AVRO-1006:
------------------------------------

A few minor nits:
 - the 'href' in one of the documentation links is missing its 'h'
 - the WHITESPACE comment should perhaps read, "Eliminate all whitespace in JSON outside of
string literals."
 - we might define a nested FingerprintAlgorithm Enum for the implemented fingerprint algorithm
names.
 - SchemaNormalization should probably have a private constructor, e.g., 'private SchemaNormalization()
{}'
 - the #fingerprint link in the class documentation is broken.

Otherwise I'm +1 and look forward to committing this early next week unless there are objections.

are designed such that the chances of collisions is very, very low.
