22.129. Release 0.56
Tables can be created from the result of a query:
CREATE TABLE orders_by_date AS SELECT orderdate, sum(totalprice) AS price FROM orders GROUP BY orderdate
Tables are created in Hive without partitions (unpartitioned) and use
RCFile with the Binary SerDe (
LazyBinaryColumnarSerDe) as this is
currently the best format for Presto.
This is a backwards incompatible change to
ConnectorMetadata in the SPI,
so if you have written a connector, you will need to update your code before
deploying this release. We recommend changing your connector to extend from
ReadOnlyConnectorMetadata abstract base class unless you want to
support table creation.
Cross joins are supported using the standard ANSI SQL syntax:
SELECT * FROM a CROSS JOIN b
Inner joins that result in a cross join due to the join criteria evaluating to true at analysis time are also supported.
