Accelerating Lakehouse Table Performance - The Complete Guide
Blog post from Onehouse
Pioneered by Uber in 2016, the concept of the data lakehouse, epitomized by Apache Hudi, Apache Iceberg, and Delta Lake, aims to efficiently store and manage large volumes of data by decoupling storage and compute. These technologies enable scalability and cost-efficiency but necessitate careful performance tuning to optimize write and read operations. Onehouse, an evolution of the Apache Hudi team, focuses on building an interoperable data lakehouse platform that emphasizes effective table performance. Key optimization strategies include selecting appropriate table types (Copy on Write or Merge on Read), optimizing partitioning strategies, and leveraging indexing to enhance query performance. The use of clustering techniques, such as Z-order and Hilbert curves, further enhances data organization for efficient querying. Additionally, table services like cleaning, clustering, and compaction play crucial roles in maintaining table health and performance, with asynchronous execution providing an edge in speeding up operations. Onehouse aims to simplify these optimizations through its platform and tools, offering a streamlined approach to managing data lakehouse deployments.
