The record

Purpose: Apache Paimon is a lake format for building realtime lakehouse architectures with streaming and batch operations using Flink and Spark.
Realtime updates: Primary key tables support large-scale updates and configurable merge engines, including deduplication, partial updates, aggregation, and first-row updates.
Append processing: Append tables support large-scale batch and streaming processing, automatic small-file merging, and data compaction with Z-order sorting.
Data management: Paimon supports ACID transactions, time travel, schema evolution, and metadata for petabyte-scale datasets and many partitions.
Compute integrations: The ecosystem compatibility page lists integrations for Flink, Spark, Hive, Trino, Presto, StarRocks, and Doris, with supported operations varying by engine.
CDC ingestion: The project homepage lists CDC pipelines for MySQL, PostgreSQL, Kafka, MongoDB, and Pulsar.
Multimodal and Python: The homepage describes vector search, full-text search, blob tables, and a Python SDK with integrations including Ray, PyTorch, and Pandas.
Storage: Documented filesystem options include local files, HDFS, Aliyun OSS, S3, Tencent COS, Azure Storage, Huawei OBS, and Google Cloud Storage.
Python client: PyPaimon provides catalog, table, Arrow, and pandas APIs plus a command-line tool; core table reads and writes do not require a JVM or a running Flink or Spark cluster.
Deployment requirement: Engine integrations require a matching connector or built-in integration and access to the catalog and warehouse storage; distributed clusters need shared storage available to participating processes.
Security model: The project says trust and authorization boundaries are generally enforced by the surrounding catalog, engine, service, operator configuration, and storage authorization.
Vulnerability reporting: The project directs users to report possible vulnerabilities privately to [email protected] and not disclose them publicly before the project responds.
Support: The project directs users to its user mailing list and GitHub issue tracker for help and issue reporting.
Analytics: The project describes petabyte-scale tables with time travel, fast scan planning, schema evolution, and incremental clustering.
