Migrating from Apache Iceberg to Apache Hudi
Tags:
You can adopt Apache Hudi on an existing Apache Iceberg table either by translating its metadata with Apache XTable — no data rewrite, since both formats store data as Parquet files — or via a one-time rewrite; and because XTable also works in the reverse direction

Migrating from Delta Lake to Apache Hudi
Tags:
You can migrate a Delta Lake table to Apache Hudi either by translating its metadata with Apache XTable — no data rewrite required, since both formats store data as Apache Parquet — or by rewriting the table once with a Spark bulk_insert; many teams start by running

Apache Hudi - The Data Lake Platform
Tags:
Apache Hudi is a streaming data lake platform built around a database kernel—not merely a table format or a transactional layer, but a complete software stack with built-in table services, data services, and incremental processing capabilities

Security Model
Apache Hudi is a library that relies on the security posture of the underlying compute engine and storage environment in which it operates

Migrating from Apache Hive Tables to Apache Hudi
Tags:
Migrating an Apache Hive table to Apache Hudi means converting its underlying data files into a Hudi table — either in place with Hudi's bootstrap mechanism or by rewriting the data with Spark — and re-registering it in your metastore through Hudi's catalog

Migrating from Parquet to Apache Hudi: A Practical Guide
Tags:
You can migrate existing Parquet datasets to Apache Hudi either in place — using Hudi's bootstrap operation, which adds Hudi metadata without rewriting data files — or by rewriting the data through a one-time bulk insert

Apache Hudi vs Delta Lake for Write-Heavy Workloads
Tags:
For update- and delete-heavy tables, the core architectural difference is this: Apache Hudi locates the records being changed through pluggable indexes — including a record-level index that maps each key to its file group — and can absorb changes into Merge

https://hudi.apache.org/blog/2026/07/14/what-is-an-open-table-format
Apache Hudi, Apache Iceberg, Delta Lake, and Apache Paimon are the major open table formats; in all of them the data itself stays in open file formats like Apache Parquet or Apache ORC
