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 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/2021/07/21/streaming-data-lake-platform
Streaming: At its core, by optimizing for fast upserts & change streams, Hudi provides the primitives to data lake workloads that are comparable to what Apache Kafka does for event-streaming (namely, incremental produce/consume of events and a state-store for interactive querying)
https://hudi.apache.org/blog/2026/07/14/what-is-an-open-table-format
The designs are converging here: proposals in the Iceberg community for format version 4 — single-file commits and an adaptive root manifest — would move its commit metadata toward the log-structured approach Hudi's timeline and Delta's transaction log have used from the beginning, though these are not yet part of
https://hudi.apache.org/blog/2026/07/22/what-is-cdc-on-a-data-lake
Doing this efficiently means quickly finding which file holds a given key — Hudi does so with pluggable indexes, including a record-level index, so it does not have to scan the table on every write

Apache Hudi vs Apache Iceberg for Streaming Ingestion

Both Apache Hudi and Apache Iceberg can ingest streaming data, but they are built around different assumptions about how often a table is written to

This post walks through what each of the four letters means concretely at the file level, how lakes worked before table formats existed, how formats like Apache Hudi deliver these guarantees, and — just as important — what ACID on a lake does not promise

Migrating from Apache Hive Tables to Apache Hudi

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

How Open Table Formats Make Upserts Possible
Open table formats — Apache Hudi, Apache Iceberg, and Delta Lake — introduced a transactional metadata layer on top of immutable files, turning a directory of Parquet files into a proper table

Projects like Apache Hudi, Apache Iceberg, and Delta Lake define tables (not just files) over Parquet and ORC, and bring the database capabilities the lake was missing:
ACID transactions with concurrency control, so writers commit atomically and readers never see partial results
