+
+Apache DataFusion Comet is a high-performance accelerator for Apache Spark,
built on top of the powerful
+[Apache DataFusion] query engine. Comet is designed to significantly enhance
the
+performance of Apache Spark workloads while leveraging commodity hardware and
seamlessly integrating with the
+Spark ecosystem without requiring any code changes.
+
+Comet also accelerates Apache Iceberg, when performing Parquet scans from
Spark.
+
+[Apache DataFusion]: https://datafusion.apache.org
+
+## Run Spark Queries at DataFusion Speeds
+
+Comet delivers a performance speedup for many queries, enabling faster data
processing and shorter time-to-insights.
+
+The following chart shows the time it takes to run the 22 TPC-H queries
against 100 GB of data in Parquet format
+using a single executor with 8 cores. See the [Comet Benchmarking
Guide](https://datafusion.apache.org/comet/contributor-guide/benchmarking.html)
+for details of the environment used for these benchmarks.
+
+When using Comet, the overall run time is reduced from 652 seconds to 268
seconds, a 2.4x speedup.
+
+
+
+Here is a breakdown showing relative performance of Spark and Comet for each
TPC-H query.
+
+
+
+These benchmarks can be reproduced in any environment using the documentation
in the
+[Comet Benchmarking Guide](/contributor-guide/benchmarking.md). We encourage
+you to run your own benchmarks.
+
+## Use Commodity Hardware
+
+Comet leverages commodity hardware, eliminating the need for costly hardware
upgrades or
+specialized hardware accelerators, such as GPUs or FPGA. By maximizing the
utilization of commodity hardware, Comet
+ensures cost-effectiveness and scalability for your Spark deployments.
+
+## Spark Compatibility
+
+Comet aims for 100% compatibility with all supported versions of Apache Spark,
allowing you to integrate Comet into
+your existing Spark deployments and workflows seamlessly. With no code changes
required, you can immediately harness
+the benefits of Comet's acceleration capabilities without disrupting your
Spark applications.
+
+## Tight Integration with Apache DataFusion
+
+Comet tightly integrates with the core Apache DataFusion project, leveraging
its powerful execution engine. With
+seamless interoperability between Comet and DataFusion, you can achieve
optimal performance and efficiency in your
+Spark workloads.
+
+## Active Community
+
+Comet boasts a vibrant and active community of developers, contributors, and
users dedicated to advancing the
+capabilities of Apache DataFusion and accelerating the performance of Apache
Spark.
