> Spark with Glue as external catalog
> -----------------------------------
>                 Key: SPARK-23443
>                 URL: https://issues.apache.org/jira/browse/SPARK-23443
>             Project: Spark
>          Issue Type: New Feature
>          Components: Spark Core
>    Affects Versions: 2.4.0
>            Reporter: Ameen Tayyebi
>            Priority: Major
> AWS Glue Catalog is an external Hive metastore backed by a web service. It 
> allows permanent storage of catalog data for BigData use cases.
> To find out more information about AWS Glue, please consult:
>  * AWS Glue - [https://aws.amazon.com/glue/]
>  * Using Glue as a Metastore catalog for Spark - 
> [https://docs.aws.amazon.com/emr/latest/ReleaseGuide/emr-spark-glue.html]
> Today, the integration of Glue and Spark is through the Hive layer. Glue 
> implements the IMetaStore interface of Hive and for installations of Spark 
> that contain Hive, Glue can be used as the metastore.
> The feature set that Glue supports does not align 1-1 with the set of 
> features that the latest version of Spark supports. For example, Glue 
> interface supports more advanced partition pruning that the latest version of 
> Hive embedded in Spark.
> To enable a more natural integration with Spark and to allow leveraging 
> latest features of Glue, without being coupled to Hive, a direct integration 
> through Spark's own Catalog API is proposed. This Jira tracks this work.
