Subject [jira] [Commented] (BLUR-165) Allow columns to be added dynamically
Date Thu, 27 Jun 2013 11:20:20 GMT

    [ https://issues.apache.org/jira/browse/BLUR-165?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13694625#comment-13694625

Aaron McCurry commented on BLUR-165:
------------------------------------

So for the addColumnDefinition(family,name,type,analyzer,fulltext) call, there should probably
be another param subname addColumnDefinition(family,name,subname,type,analyzer,fulltext).
 Subfields are used to index the data a different way without storing the fields more than
once.  There are also going to be some rules about what's allowed.

- Family and name can not be null.
- If the type is NOT Text then analyzer has to be null.
- If the subname is filled in, there has to be a field Family + name column already defined
- And if it's a subfield then fulltext has to be false

> Modify Column struct to add type and once defined we should not allow updates for existing
column definitions
> Make changes to the way analyzer is stored in zookeeper 
> From an external api (Thrift), I would think we would need a method that looks like "addColumnDefinition(family,name,type,analyzer,fulltext)"
or something like that
> Update ZkCacheMap and store the new column definition in zookeeper
