* [SPARK-9759] [SQL] improve decimal.times() and cast(int, decimalType)Davies Liu2015-08-102-32/+22
| | | | | | | | | | | | | | | | This patch optimize two things: 1. passing MathContext to JavaBigDecimal.multiply/divide/reminder to do right rounding, because java.math.BigDecimal.apply(MathContext) is expensive 2. Cast integer/short/byte to decimal directly (without double) This two optimizations could speed up the end-to-end time of a aggregation (SUM(short * decimal(5, 2)) 75% (from 19s -> 10.8s) Author: Davies Liu <davies@databricks.com> Closes #8052 from davies/optimize_decimal and squashes the following commits: 225efad [Davies Liu] improve decimal.times() and cast(int, decimalType)

* [SPARK-9743] [SQL] Fixes JSONRelation refreshingCheng Lian2015-08-104-12/+21
| | | | | | | | | | | | | | | | | PR #7696 added two `HadoopFsRelation.refresh()` calls ([this] [1], and [this] [2]) in `DataSourceStrategy` to make test case `InsertSuite.save directly to the path of a JSON table` pass. However, this forces every `HadoopFsRelation` table scan to do a refresh, which can be super expensive for tables with large number of partitions. The reason why the original test case fails without the `refresh()` calls is that, the old JSON relation builds the base RDD with the input paths, while `HadoopFsRelation` provides `FileStatus`es of leaf files. With the old JSON relation, we can create a temporary table based on a path, writing data to that, and then read newly written data without refreshing the table. This is no long true for `HadoopFsRelation`. This PR removes those two expensive refresh calls, and moves the refresh into `JSONRelation` to fix this issue. We might want to update `HadoopFsRelation` interface to provide better support for this use case.

* [SPARK-9703] [SQL] Refactor EnsureRequirements to avoid certain unnecessary ↵Josh Rosen2015-08-095-65/+328
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | shuffles This pull request refactors the `EnsureRequirements` planning rule in order to avoid the addition of certain unnecessary shuffles. As an example of how unnecessary shuffles can occur, consider SortMergeJoin, which requires clustered distribution and sorted ordering of its children's input rows. Say that both of SMJ's children produce unsorted output but are both SinglePartition. In this case, we will need to inject sort operators but should not need to inject Exchanges. Unfortunately, it looks like the EnsureRequirements unnecessarily repartitions using a hash partitioning. This patch solves this problem by refactoring `EnsureRequirements` to properly implement the `compatibleWith` checks that were broken in earlier implementations. See the significant inline comments for a better description of how this works. The majority of this PR is new comments and test cases, with few actual changes to the code.

* [SPARK-8890] [SQL] Fallback on sorting when writing many dynamic partitionsMichael Armbrust2015-08-0710-623/+715
| | | | | | | | | | | | | | | | | | | | | | | Previously, we would open a new file for each new dynamic written out using `HadoopFsRelation`. For formats like parquet this is very costly due to the buffers required to get good compression. In this PR I refactor the code allowing us to fall back on an external sort when many partitions are seen. As such each task will open no more than `spark.sql.sources.maxFiles` files. I also did the following cleanup: - Instead of keying the file HashMap on an expensive to compute string representation of the partition, we now use a fairly cheap UnsafeProjection that avoids heap allocations. - The control flow for instantiating and invoking a writer container has been simplified. Now instead of switching in two places based on the use of partitioning, the specific writer container must implement a single method `writeRows` that is invoked using `runJob`. - `InternalOutputWriter` has been removed. Instead we have a `private[sql]` method `writeInternal` that converts and calls the public method. This method can be overridden by internal datasources to avoid the conversion. This change remove a lot of code duplication and per-row `asInstanceOf` checks. - `commands.scala` has been split up.

* [SPARK-9709] [SQL] Avoid starving unsafe operators that use sortAndrew Or2015-08-068-22/+184
| | | | | | | | | | | | | | | | | The issue is that a task may run multiple sorts, and the sorts run by the child operator (i.e. parent RDD) may acquire all available memory such that other sorts in the same task do not have enough to proceed. This manifests itself in an `IOException("Unable to acquire X bytes of memory")` thrown by `UnsafeExternalSorter`. The solution is to reserve a page in each sorter in the chain before computing the child operator's (parent RDD's) partitions. This requires us to use a new special RDD that does some preparation before computing the parent's partitions.
