This can be done later, right? You'd have to do it in hbase.
{quote}
Yep
{quote}
Are we saying the default ns is called 'default'? Or that it has no name?
{quote}
It has no name similar to the java default package.
{quote}
Is this so we can get callbacks on change? (I wish we had in place a general
config. change notification mechanism that this could leverage rather than have
to build its own)
{quote}
I wish too. We can refactor after this to create one?
{quote}
How much of this design has to be in place for 0.96 to ship?
{quote}
We're watching out for backwards compatibility? I believe core namespace should
be enough. We can put the rest in 96.1, quota stuff needs addition to the cli.
Security has some changes as well to support namespaces but it's just an
extension.
{quote}
Below is interesting (smile)
{quote}
It's our secret version ;-)
{quote}
Patch introduces TableName and TableName is used to hold namespace and the name
of the table. NS is a concept superior to tables. It should be elsewhere, in a
NS object? (model seems off).
{quote}
My line of thinking was that namespace is a component of tableName ie
"tableName = <table namespace>.<table qualifier>". Just like column = CF:CQ.
{quote}
NamespaceDesc.. has notion of groups. Is that right given they are add on for
later?
{quote}
Where did you see that? Group information is added as a KV pair to the
NamespaceDesc.
{quote}
NamespaceDescriptor implements java Serializable
{quote}
Oops will remove that
