> Support partition pruning for InMemoryCatalog
> ---------------------------------------------
>
> Key: SPARK-20194
> URL: https://issues.apache.org/jira/browse/SPARK-20194
> Project: Spark
> Issue Type: Improvement
> Components: Optimizer
> Affects Versions: 2.1.0
> Reporter: Adrian Ionescu
>
> {{listPartitionsByFilter()}} is not yet implemented for {{InMemoryCatalog}}:
> {quote}
> // TODO: Provide an implementation
> throw new UnsupportedOperationException(
> "listPartitionsByFilter is not implemented for InMemoryCatalog")
> {quote}
> Because of this, there is a hack in {{FindDataSourceTable}} that avoids
> passing along the {{CatalogTable}} to the {{DataSource}} it creates when the
> catalog implementation is not "hive", so that, when the latter is resolved,
> an {{InMemoryFileIndex}} is created instead of a {{CatalogFileIndex}} which
> the {{PruneFileSourcePartitions}} rule matches for.
