Apache Hudi
What it is
Apache Hudi is an open-source data lakehouse platform for adding database functions to data lakes and supporting incremental processing for low-latency analytics. It runs on Linux and can be self-hosted. Hudi supports updates and deletions, including change data capture and streaming workloads, with pluggable indexing. Its transaction features include atomic writes, snapshot isolation and non-blocking concurrency controls. Users can query prior table versions, roll back changes and review commit history. Automated table services cover clustering, compaction, cleaning, file sizing and indexing; schema evolution and enforcement help tables adapt as data changes. Listed integrations include Spark, Flink, Kafka, Debezium, Amazon S3, Google Cloud Storage, Azure Blob Storage, Trino and dbt. Some integrations are read-only, in which case Spark or Flink can write tables for those systems to query. Source releases and Maven bundles are available. Hudi is free, with an open-source plan, and its security depends on the underlying compute engine and storage environment.
For and against
For
- Supports data updates and deletions, including CDC.
- Provides atomic writes and snapshot isolation.
- Offers historical queries, rollback and commit history.
- Automates several table maintenance services.
- Integrates with listed engines, storage and tools.
Against
- Some listed integrations support reading only.
- Security relies on the compute and storage environment.
- Release files should be verified with PGP signatures.
The verdict
Apache Hudi combines incremental lakehouse processing with transactional features and automated table services. Check whether the integrations you need support writing, and account for the security posture of your compute and storage environment.
Who it suits
Hudi suits teams building data lakes or lakehouses that need streaming ingestion, incremental processing and table operations. It may also fit teams working with the listed compute engines, storage services and query tools.
