New storage formats and supporting components > > We have also made several supporting components available around > Paimon, including Mosaic, paimon-vindex, and paimon-full-text-index. > > Mosaic provides a columnar-bucket hybrid file format optimized for > wide tables and efficient column projection. paimon-vindex provides > native vector indexing capabilities for Paimon. paimon-full-text-index > provides the native full-text engine used by Paimon full-text global > indexes. > > Together, these components make Paimon more capable as a storage layer > for both traditional lakehouse workloads and emerging AI/multimodal > workloads. > > 6. Ecosystem improvements > > We have continued to improve Flink, Spark, Python, Ray, and Daft > integration, and have been adding more end-to-end coverage for > Java/Python interoperability, global index creation and reading, > vector data, full-text search, and data evolution workflows. > > Given the scope of these changes, I think it is a good time to discuss > whether we should cut a 2.0.0 release.
