Subject [jira] Commented: (HBASE-1744) Thrift server to match the new java api.
Date Mon, 14 Feb 2011 23:55:57 GMT

    [ https://issues.apache.org/jira/browse/HBASE-1744?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12994573#comment-12994573

ryan rawson commented on HBASE-1744:
------------------------------------

talking about this recently with stack, I made the point that we should probably put the new
API in the same package/thrift file as the old.  Use new symbols, at the end of the .thrift
file. That way people can use new and old clients with the same server, making migration easier.
It might make some names a little ugly (we could go with the windowsy Ex suffix?) but making
an easier migration strategy is important I feel.

> This mutateRows, etc.. is a little confusing compared to the new cleaner java client.
> Thinking of ways to make a thrift client that is just as elegant. something like:
> void put(1:Bytes table, 2:TPut put) throws (1:IOError io)
> with:
> struct TColumn {
>   1:Bytes family,
>   2:Bytes qualifier,
>   3:i64 timestamp
> }
> struct TPut {
>   1:Bytes row,
>   2:map<TColumn, Bytes> values
> }
> This creates more verbose rpc  than if the columns in TPut were just map<Bytes, map<Bytes,
Bytes>>, but that is harder to fit timestamps into and still be intuitive from say python.
> Presumably the goal of a thrift gateway is to be easy first.
