Delta Lake — Technology Profile & Architecture

Core Information

#core_information

Name, description, vendor website, logo, technology type and tags.

Overview & Role

Delta Lake is an open-source storage layer that brings ACID transactions to Apache Spark and big data workloads. It enables building a Lakehouse architecture on top of existing data lakes, providing reliability, security, and performance for both streaming and batch operations. Key features include ACID transactions, scalable metadata handling, and unified streaming and batch data processing.

Domain Classification & Tags

Storage

Performance Profile

#performance_profile

Typical read and write throughput, payload size and processing latency.

Read Performance Profile

Throughput: Varies greatly with data size and query complexity, potentially hundreds of GB/s for large scans on optimized clusters

Payload Size: Varies from single rows (KB) to full tables (TB)

Processing Latency: Sub-second for small queries, minutes for complex analytical queries on large datasets

Write Performance Profile

Throughput: Tens of thousands of records/sec to hundreds of MB/s, depending on cluster size and write pattern (append vs. upsert)

Payload Size: Typically MBs to GBs per transaction/batch

Processing Latency: Seconds to minutes for batch writes, potentially sub-second for micro-batches or streaming appends
