Subject [jira] [Commented] (HBASE-8693) Implement extensible type API based on serialization primitives
Date Tue, 25 Jun 2013 18:01:25 GMT

    [ https://issues.apache.org/jira/browse/HBASE-8693?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13693214#comment-13693214

Nick Dimiduk commented on HBASE-8693:
-------------------------------------

bq. You kept the java name for all types, except BigDecimal, is there a reason?

The data types come from the (outdated) spec posted on HBASE-8089. I believe there is value
in choosing types that are meaningful in a SQL context, but we shouldn't limit our thinking
on this to what was laid down 30 years ago.

bq. Some unit tests could help to see how it should be used.

Agreed. Look for those in a followup patch. 

bq. For example, the constructors are private...

The idea is instances of {{HDataType}} are type definitions, not data values. For instance,
the {{o.a.h.h.t.Decimal#DECIMAL}} instance is the definition of how to encode,decode values
and how values of this type relate to values of other types. It does not represent a numeric
value.
