* [SPARK-1508][SQL] Add SQLConf to SQLContext.Zongheng Yang2014-06-104-33/+131
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This PR (1) introduces a new class SQLConf that stores key-value properties for a SQLContext (2) clean up the semantics of various forms of SET commands. The SQLConf class unlocks user-controllable optimization opportunities; for example, user can now override the number of partitions used during an Exchange. A SQLConf can be accessed and modified programmatically through its getters and setters. It can also be modified through SET commands executed by `sql()` or `hql()`. Note that users now have the ability to change a particular property for different queries inside the same Spark job, unlike settings configured in SparkConf. For SET commands: "SET" will return all properties currently set in a SQLConf, "SET key" will return the key-value pair (if set) or an undefined message, and "SET key=value" will call the setter on SQLConf, and if a HiveContext is used, it will be executed in Hive as well.

* Avoid dynamic dispatching when unwrapping Hive data.Cheng Lian2014-06-022-15/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a follow up of PR #758. The `unwrapHiveData` function is now composed statically before actual rows are scanned according to the field object inspector to avoid dynamic dispatching cost. According to the same micro benchmark used in PR #758, this simple change brings slight performance boost: 2.5% for CSV table and 1% for RCFile table. ``` Optimized version: CSV: 6870 ms, RCFile: 5687 ms CSV: 6832 ms, RCFile: 5800 ms CSV: 6822 ms, RCFile: 5679 ms CSV: 6704 ms, RCFile: 5758 ms CSV: 6819 ms, RCFile: 5725 ms Original version: CSV: 7042 ms, RCFile: 5667 ms CSV: 6883 ms, RCFile: 5703 ms CSV: 7115 ms, RCFile: 5665 ms CSV: 7020 ms, RCFile: 5981 ms CSV: 6871 ms, RCFile: 5906 ms ``` Author: Cheng Lian <lian.cs.zju@gmail.com> Closes #935 from liancheng/staticUnwrapping and squashes the following commits: c49c70c [Cheng Lian] Avoid dynamic dispatching when unwrapping Hive data.

My quick micro benchmark suggests these two optimizations made the optimized version 2x and 2.5x faster when scanning CSV table and RCFile table respectively: ``` Original: [info] CSV: 27676 ms, RCFile: 26415 ms [info] CSV: 27703 ms, RCFile: 26029 ms [info] CSV: 27511 ms, RCFile: 25962 ms Optimized: [info] CSV: 13820 ms, RCFile: 10402 ms [info] CSV: 14158 ms, RCFile: 10691 ms [info] CSV: 13606 ms, RCFile: 10346 ms ``` The micro benchmark loads a 609MB CVS file (structurally similar to the `src` test table) into a normal Hive table with `LazySimpleSerDe` and a RCFile table, then scans these tables respectively. Preparation code: ```scala package org.apache.spark.examples.sql.hive import org.apache.spark.sql.hive.LocalHiveContext import org.apache.spark.{SparkConf, SparkContext} object HiveTableScanPrepare extends App { val sparkContext = new SparkContext( new SparkConf() .setMaster("local") .setAppName(getClass.getSimpleName.stripSuffix("$"))) val hiveContext = new LocalHiveContext(sparkContext) import hiveContext._ hql("drop table scan_csv") hql("drop table scan_rcfile") hql("""create table scan_csv (key int, value string) | row format serde 'org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe' | with serdeproperties ('field.delim'=',') """.stripMargin) hql(s"""load data local inpath "${args(0)}" into table scan_csv""") hql("""create table scan_rcfile (key int, value string) | row format serde 'org.apache.hadoop.hive.serde2.columnar.ColumnarSerDe' |stored as | inputformat 'org.apache.hadoop.hive.ql.io.RCFileInputFormat' | outputformat 'org.apache.hadoop.hive.ql.io.RCFileOutputFormat' """.stripMargin) hql( """ |from scan_csv |insert overwrite table scan_rcfile |select scan_csv.key, scan_csv.value """.stripMargin) } ``` Benchmark code: ```scala package org.apache.spark.examples.sql.hive import org.apache.spark.sql.hive.LocalHiveContext import org.apache.spark.{SparkConf, SparkContext} object HiveTableScanBenchmark extends App { val sparkContext = new SparkContext( new SparkConf() .setMaster("local") .setAppName(getClass.getSimpleName.stripSuffix("$"))) val hiveContext = new LocalHiveContext(sparkContext) import hiveContext._ val scanCsv = hql("select key from scan_csv") val scanRcfile = hql("select key from scan_rcfile") val csvDuration = benchmark(scanCsv.count()) val rcfileDuration = benchmark(scanRcfile.count()) println(s"CSV: $csvDuration ms, RCFile: $rcfileDuration ms") def benchmark(f: => Unit) = { val begin = System.currentTimeMillis() f val end = System.currentTimeMillis() end - begin } } ``` @marmbrus Please help review, thanks!

* [Spark-1461] Deferred Expression Evaluation (short-circuit evaluation)Cheng Hao2014-05-151-7/+21
| | | | | | | | | | | | | | | | | | | | This patch unify the foldable & nullable interface for Expression. 1) Deterministic-less UDF (like Rand()) can not be folded. 2) Short-circut will significantly improves the performance in Expression Evaluation, however, the stateful UDF should not be ignored in a short-circuit evaluation(e.g. in expression: col1 > 0 and row_sequence() < 1000, row_sequence() can not be ignored even if col1 > 0 is false) I brought an concept of DeferredObject from Hive, which has 2 kinds of children classes (EagerResult / DeferredResult), the former requires triggering the evaluation before it's created, while the later trigger the evaluation when first called its get() method.
