The June release of ArcGIS Maps SDK for JavaScript brings advances across performance, visualization, interaction, 3D, and AI-assisted workflows \u2013 without breaking changes, so you can upgrade with confidence.<\/p>\n

Parquet: optimized performance and new functionalities<\/a><\/h2>\n

Performance of Parquet Layer<\/a> (beta) is further improved with support for Spatially Optimized Parquet files, which combine spatial clustering with a multiscale index to stream only the portions of a file needed for display. With the June release of ArcGIS Online, Spatially Optimized Parquet files can be authored with ArcGIS GeoAnalytics Engine or ArcGIS Data Pipelines, and parquet layer can be customized in Map Viewer. We also improved the performance for querying parquet layers, added supports for filtering data directly with definition expression, added advanced querying options, and more.<\/p>\n"},{"acf_fc_layout":"image","image":{"ID":2971722,"id":2971722,"title":"parquet-planery-img","filename":"parquet-planery-img-scaled.png","filesize":3763196,"url":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2026\/05\/parquet-planery-img-scaled.png","link":"https:\/\/www.esri.com\/arcgis-blog\/products\/js-api-arcgis\/announcements\/arcgis-maps-sdk-for-javascript-whats-new-in-5-1\/parquet-planery-img","alt":"","author":"330302","description":"","caption":"Displaying over 2 billion polygons using parquet layer with Spatially Optimized Parquet files.","name":"parquet-planery-img","status":"inherit","uploaded_to":2965884,"date":"2026-06-22 17:55:10","modified":"2026-06-22 17:55:28","menu_order":0,"mime_type":"image\/png","type":"image","subtype":"png","icon":"https:\/\/www.esri.com\/arcgis-blog\/wp-includes\/images\/media\/default.png","width":2560,"height":1322,"sizes":{"thumbnail":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2026\/05\/parquet-planery-img-213x200.png","thumbnail-width":213,"thumbnail-height":200,"medium":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2026\/05\/parquet-planery-img-scaled.png","medium-width":464,"medium-height":240,"medium_large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2026\/05\/parquet-planery-img-scaled.png","medium_large-width":768,"medium_large-height":397,"large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2026\/05\/parquet-planery-img-scaled.png","large-width":1920,"large-height":992,"1536x1536":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2026\/05\/parquet-planery-img-1536x793.png","1536x1536-width":1536,"1536x1536-height":793,"2048x2048":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2026\/05\/parquet-planery-img-2048x1057.png","2048x2048-width":2048,"2048x2048-height":1057,"card_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2026\/05\/parquet-planery-img-826x426.png","card_image-width":826,"card_image-height":426,"wide_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2026\/05\/parquet-planery-img-1920x991.png","wide_image-width":1920,"wide_image-height":991}},"image_position":"center","orientation":"horizontal","hyperlink":"https:\/\/developers.arcgis.com\/javascript\/latest\/sample-code\/layers-parquetlayer\/"},{"acf_fc_layout":"content","content":"

With these new updates, Parquet, the open-source columnar file format designed for efficient storage and analytics of large tabular datasets, becomes an important part of the big data workflow in Web GIS. Parquet Layer is best suited for large, read-only <\/em>datasets where scalability, efficient storage, and high-performance visualization are critical, offering a strong alternative to vector tile layers by preserving continuous feature geometries. Feature layers remain the recommended choice for operational and typical-sized datasets.<\/p>\n

Telecom domain networks<\/a><\/h2>\n
We added support for the Telecom Domain Network<\/a> \u2014 a powerful capability first introduced for telecom companies in ArcGIS Pro 3.7 and ArcGIS Enterprise 12.1.
