And then, ... listen to their slogan.. "you can stores own arbitrary data type. look!! this is awesome flexible DB solution. Let's make your own datum and data types. "..... We can think about why they didn't... Let's view the matter. Built-in Data Types does not interrupt the frexible because it's just a function for the convenience of users. {code} only byte[] VS { integer or character or byte[] or .... , etc} {code} It means that each time users needn't tiresome of develop the provided built-in data types. was (Author: udanax): Above comment means... "I didn't said that Hbase should provides built-in data type." Let's see the example. Some DB solutions can be provide only byte[] data type. And then, ... listen to their slogan.. "you can stores own arbitrary data type. look!! this is awesome flexible DB solution. Let's make your own datum and data types. "..... We can think about why they didn't... Also, i think it is not makes any problem. It's just a function for the convenience of users. # only byte[] VS { integer or character or byte[] or .... , etc} It means that each user needn't develop for the provided built-in data type in everytime. > [Hbase Shell] Addition of Built-In Value Data Types for efficient accessing > and stroing data > -------------------------------------------------------------------------------------------- > > Key: HADOOP-2329 > URL: https://issues.apache.org/jira/browse/HADOOP-2329 > Project: Hadoop > Issue Type: New Feature > Components: contrib/hbase > Affects Versions: 0.16.0 > Reporter: Edward Yoon > Assignee: Edward Yoon > Fix For: 0.16.0 > > > A built-in data type is a fundamental data type that the hbase shell defines. > (character strings, scalars, ranges, arrays, ... , etc) > If you need a specialized data type that is not currently provided as a > built-in type, > you are encouraged to write your own user-defined data type using UDC(not yet > implemented). > (or contribute it for distribution in a future release of hbase shell) -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
