Amazon EMR 7.5 runtime for Apache Spark and Iceberg can run Spark workloads 3.6 occasions sooner than Spark 3.5.3 and Iceberg 1.6.1

The Amazon EMR runtime for Apache Spark affords a high-performance runtime atmosphere whereas sustaining 100% API compatibility with open supply Apache Spark and Apache Iceberg desk format. Amazon EMR on EC2, Amazon EMR Serverless, Amazon EMR on Amazon EKS, Amazon EMR on AWS Outposts and AWS Glue all use the optimized runtimes.

On this submit, we show the efficiency advantages of utilizing the Amazon EMR 7.5 runtime for Spark and Iceberg in comparison with open supply Spark 3.5.3 with Iceberg 1.6.1 tables on the TPC-DS 3TB benchmark v2.13.

Iceberg is a well-liked open supply high-performance format for giant analytic tables. Our benchmarks show that Amazon EMR can run TPC-DS 3 TB workloads 3.6 occasions sooner, decreasing the runtime from 1.54 hours to 0.42 hours. Moreover, the associated fee effectivity improves by 2.9 occasions, with the whole value reducing from $16.00 to $5.39 when utilizing Amazon Elastic Compute Cloud (Amazon EC2) On-Demand r5d.4xlarge cases, offering observable good points for knowledge processing duties.

This can be a additional 32% enhance from the optimizations shipped in Amazon EMR 7.1 lined in a earlier submit, Amazon EMR 7.1 runtime for Apache Spark and Iceberg can run Spark workloads 2.7 occasions sooner than Apache Spark 3.5.1 and Iceberg 1.5.2. Since then we’ve got continued including extra help for DataSource V2 for eight extra current question optimizations within the EMR runtime for Spark.

Along with these DataSource V2 particular enhancements, we’ve got made extra optimizations to Spark operators since Amazon EMR 7.1 that additionally contribute to the extra speedup.

Benchmark outcomes for Amazon EMR 7.5 in contrast to4 open supply Spark 3.5.3 and Iceberg 1.6.1

To evaluate the Spark engine’s efficiency with the Iceberg desk format, we carried out benchmark checks utilizing the 3 TB TPC-DS dataset, model 2.13 (our outcomes derived from the TPC-DS dataset are usually not straight akin to the official TPC-DS outcomes because of setup variations). Benchmark checks for the EMR runtime for Spark and Iceberg had been performed on Amazon EMR 7.5 EC2 clusters vs open supply Spark 3.5.3 and Iceberg 1.6.1 on EC2 clusters.

The setup directions and technical particulars can be found in our GitHub repository. To reduce the affect of exterior catalogs like AWS Glue and Hive, we used the Hadoop catalog for the Iceberg tables. This makes use of the underlying file system, particularly Amazon S3, because the catalog. We will outline this setup by configuring the property spark.sql.catalog..kind. The very fact tables used the default partitioning by the date column, which have a variety of partitions various from 200–2,100. No precalculated statistics had been used for these tables.

We ran a complete of 104 SparkSQL queries in three sequential rounds, and the common runtime of every question throughout these rounds was taken for comparability. The typical runtime for the three rounds on Amazon EMR 7.5 with Iceberg enabled was 0.42 hours, demonstrating a 3.6-fold velocity enhance in comparison with open supply Spark 3.5.3 and Iceberg 1.6.1. The next determine presents the whole runtimes in seconds.

The next desk summarizes the metrics.

*Detailed value estimates are mentioned later on this submit.

The next chart demonstrates the per-query efficiency enchancment of Amazon EMR 7.5 relative to open supply Spark 3.5.3 and Iceberg 1.6.1. The extent of the speedup varies from one question to a different, with the quickest as much as 9.4 occasions sooner for q93, with Amazon EMR outperforming open supply Spark with Iceberg tables. The horizontal axis arranges the TPC-DS 3TB benchmark queries in descending order based mostly on the efficiency enchancment seen with Amazon EMR, and the vertical axis depicts the magnitude of this speedup as a ratio.

Price comparability

Our benchmark offers the whole runtime and geometric imply knowledge to evaluate the efficiency of Spark and Iceberg in a posh, real-world resolution help situation. For extra insights, we additionally study the associated fee facet. We calculate value estimates utilizing formulation that account for EC2 On-Demand cases, Amazon Elastic Block Retailer (Amazon EBS), and Amazon EMR bills.

• Amazon EC2 value (consists of SSD value) = variety of cases * r5d.4xlarge hourly price * job runtime in hours
  • r5d.4xlarge hourly price = $1.152 per hour in us-east-1
• Root Amazon EBS value = variety of cases * Amazon EBS per GB-hourly price * root EBS quantity dimension * job runtime in hours
• Amazon EMR value = variety of cases * r5d.4xlarge Amazon EMR value * job runtime in hours
  • 4xlarge Amazon EMR value = $0.27 per hour
• Complete value = Amazon EC2 value + root Amazon EBS value + Amazon EMR value

The calculations reveal that the Amazon EMR 7.5 benchmark yields a 2.9-fold value effectivity enchancment over open supply Spark 3.5.3 and Iceberg 1.6.1 in operating the benchmark job.

Along with the time-based metrics mentioned to this point, knowledge from Spark occasion logs present that Amazon EMR scanned roughly 3.4 occasions much less knowledge from Amazon S3 and 4.1 occasions fewer data than the open supply model within the TPC-DS 3 TB benchmark. This discount in Amazon S3 knowledge scanning contributes on to value financial savings for Amazon EMR workloads.

Run open supply Spark benchmarks on Iceberg tables

We used separate EC2 clusters, every geared up with 9 r5d.4xlarge cases, for testing each open supply Spark 3.5.3 and Amazon EMR 7.5 for Iceberg workload. The first node was geared up with 16 vCPU and 128 GB of reminiscence, and the eight employee nodes collectively had 128 vCPU and 1024 GB of reminiscence. We performed checks utilizing the Amazon EMR default settings to showcase the standard consumer expertise and minimally adjusted the settings of Spark and Iceberg to take care of a balanced comparability.

The next desk summarizes the Amazon EC2 configurations for the first node and eight employee nodes of kind r5d.4xlarge.

Stipulations

The next conditions are required to run the benchmarking:

1. Utilizing the directions within the emr-spark-benchmark GitHub repo, arrange the TPC-DS supply knowledge in your S3 bucket and in your native pc.
2. Construct the benchmark software following the steps supplied in Steps to construct spark-benchmark-assembly software and replica the benchmark software to your S3 bucket. Alternatively, copy spark-benchmark-assembly-3.5.3.jar to your S3 bucket.
3. Create Iceberg tables from the TPC-DS supply knowledge. Observe the directions on GitHub to create Iceberg tables utilizing the Hadoop catalog. For instance, the next code makes use of an EMR 7.5 cluster with Iceberg enabled to create the tables:

aws emr add-steps 
--cluster-id  --steps Sort=Spark,Title="Create Iceberg Tables",

Summarize the outcomes

After the Spark job finishes, retrieve the check consequence file from the output S3 bucket at s3:///benchmark_run/timestamp=xxxx/abstract.csv/xxx.csv. This may be carried out both by way of the Amazon S3 console by navigating to the desired bucket location or through the use of the AWS Command Line Interface (AWS CLI). The Spark benchmark software organizes the information by making a timestamp folder and inserting a abstract file inside a folder labeled abstract.csv. The output CSV recordsdata include 4 columns with out headers:

• Question identify
• Median time
• Minimal time
• Most time

With the information from three separate check runs with one iteration every time, we are able to calculate the common and geometric imply of the benchmark runtimes.
