Hyukjin Kwon updated SPARK-15712:
---------------------------------
Labels: bulk-closed (was: )
> Proper temp table support
> -------------------------
>
> Key: SPARK-15712
> URL: https://issues.apache.org/jira/browse/SPARK-15712
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Reporter: Yin Huai
> Priority: Major
> Labels: bulk-closed
>
> For proper temp table support, I am proposing to create a temp dir for every
> {{SparkSession}}. This can be done through the following changes:
> # We add a root temp dir (the path is configurable).
> # For every {{SparkSession}}, we create a temp dir for this {{SparkSession}}
> in the root temp dir.
> To make the semantic of {{CREATE TEMP TABLE ... USING ... OPTIONS ... AS
> SELECT}} easier to understand, I am proposing the following changes:
> # We only allow {{FileFormat}} data sources used by this command.
> # We make {{USING}} clause optional and by default we use the data source set
> in {{spark.sql.sources.default}}.
> # We do not allow users to add path in the {{OPTIONS}}
> # We save the temp table in the temp location associated with the current
> {{SparkSession}}.
