Separating logical and physical table name, ie. Having a Phoenix table > point to an Hbase table with a different name have some advantages. > An example is this: Let's say we want to have a different storage/encoding > scheme for an index. We can build the new index while the clients use the old > index and once the index is rebuilt, we can momentarily start pointing to the > new index table without much downtime or performance implications. For the > client, they are using the same index with the same name, but the physical > table is different. Today, in order to change the index like this, we have to > drop it and re-create which is a downtime for the index and the data table > full scans are used for queries impacting performance while the index > creation goes on. -- This message was sent by Atlassian Jira (v8.3.4#803005)
