-------------------------------------
Summary: Support CREATE TABLE ... ASYNC to add empty key value
through MR when mapping to existing HBase table
Key: PHOENIX-3125
URL: https://issues.apache.org/jira/browse/PHOENIX-3125
Project: Phoenix
Issue Type: Bug
Reporter: James Taylor
Often times, when a Phoenix table is created to map to an existing HBase table
that is large, the CREATE TABLE statement times out. This is because Phoenix
needs to write an empty/marker KeyValue to every row (for the reason, see
here[1]) which takes a while for larger tables.
We should support the ASYNC keyword at the end of the CREATE TABLE statement to
allow a MR job to be used instead of our synchronous mechanism to prevent this
timeout. We'd also need a status on the table which is set upon completion so
that we know when we can start using it. I suppose we could overload the
INDEX_STATUS column and eventually change it's name to just STATUS.
