Built on the scalability and performance benefits of Parquet, these layers enable organizations to bring large volumes of data into ArcGIS Online through ArcGIS Data Pipelines and use them in maps and applications.<\/p>\n<p>The November 2026 update builds on that foundation with new capabilities now available in ArcGIS Online. Enhancements include support for date and time fields, time series visualization in Map Viewer, charts, refresh intervals, and saving layer configurations. The update also expands application support and introduces a new Parquet collection export format for analytics and data engineering workflows. Together, these enhancements make Parquet feature layers easier to use across the ArcGIS platform, allowing organizations to integrate large datasets into familiar workflows for mapping, sharing, and decision-making.<\/p>\n<h3><strong>Parquet feature layer enhancements<\/strong><\/h3>\n<p>Parquet feature layers include several enhancements that expand the types of data and workflows they can support. They also provide more ways to work with and manage the layer directly from its item page.<\/p>\n<ul>\n<li><strong>Support for more fields<\/strong> \u2013 Feature services have a 1,024-field limit, while Parquet feature layers can support larger schemas. This allows datasets with large numbers of attributes to be used without reducing the schema.<\/li>\n<li><strong>Expanded date and time support<\/strong> \u2013 Parquet feature layers now support Parquet date and time types and convert them to corresponding Esri field types. They also support Esri date and time field types, except timestamp offset fields. Timestamp offset fields do not have an equivalent Parquet field type. Timestamp offset fields can be removed or converted to a supported field type using <a href=\"https:\/\/doc.arcgis.com\/en\/data-pipelines\/latest\/process\/tool-overview.htm\">ArcGIS Data Pipelines tools<\/a>.<\/li>\n<li><strong>Save layer configurations\u00a0<\/strong> \u2013 You can now save layer configurations with the Parquet feature layer and reuse them across maps. Saved configurations include symbology, filters, effects, aggregation, pop-ups, fields, labels, charts, blending, transparency, visible range, time series, and refresh interval, allowing the configured layer to be reused across maps. Save is available in Map Viewer and from the Visualization tab on the item page.<\/li>\n<li><strong>Save as a new item<\/strong> &#8211; Save As creates a new layer item with its own saved configuration, but the Parquet data is not copied to the new item. The new item continues to reference the data from the source Parquet feature layer. The source layer must therefore be shared with the same users or groups for them to access the data. Save is available in Map Viewer and from the Visualization tab on the item page.<\/li>\n<li><strong>Data tab<\/strong> \u2013 Review the layer&#8217;s table and fields directly from the item page without opening the layer in Map Viewer. The table and schema are read-only.<\/li>\n<li><strong>Visualization tab<\/strong> \u2013 View the spatial data and configure the layer directly from its item page. Save configuration changes to the existing Parquet feature layer or use Save As to create a new Parquet feature layer item.<\/li>\n<\/ul>\n"},{"acf_fc_layout":"image","image":{"ID":2987983,"id":2987983,"title":"Data and Vis tabs optimize","filename":"Data-and-Vis-tabs-optimize.gif","filesize":24654456,"url":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2026\/11\/Data-and-Vis-tabs-optimize.gif","link":"https:\/\/www.esri.com\/arcgis-blog\/products\/arcgis-online\/announcements\/whats-new-for-parquet-feature-layers-beta-november-2026\/data-and-vis-tabs-optimize","alt":"Parquet feature layer showing the Data tab and changes to the layer\u2019s pop-up and style before saving the updated configuration.","author":"437412","description":"","caption":"","name":"data-and-vis-tabs-optimize","status":"inherit","uploaded_to":2986746,"date":"2026-11-06 20:53:51","modified":"2026-11-06 21:02:10","menu_order":0,"mime_type":"image\/gif","type":"image","subtype":"gif","icon":"https:\/\/www.esri.com\/arcgis-blog\/wp-includes\/images\/media\/default.png","width":1920,"height":1080,"sizes":{"thumbnail":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2026\/11\/Data-and-Vis-tabs-optimize.gif","thumbnail-width":213,"thumbnail-height":120,"medium":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2026\/11\/Data-and-Vis-tabs-optimize.gif","medium-width":464,"medium-height":261,"medium_large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2026\/11\/Data-and-Vis-tabs-optimize.gif","medium_large-width":768,"medium_large-height":432,"large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2026\/11\/Data-and-Vis-tabs-optimize.gif","large-width":1920,"large-height":1080,"1536x1536":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2026\/11\/Data-and-Vis-tabs-optimize.gif","1536x1536-width":1536,"1536x1536-height":864,"2048x2048":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2026\/11\/Data-and-Vis-tabs-optimize.gif","2048x2048-width":1920,"2048x2048-height":1080,"card_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2026\/11\/Data-and-Vis-tabs-optimize.gif","card_image-width":826,"card_image-height":465,"wide_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2026\/11\/Data-and-Vis-tabs-optimize.gif","wide_image-width":1920,"wide_image-height":1080}},"image_position":"center","orientation":"horizontal","hyperlink":""},{"acf_fc_layout":"content","content":"<h3><strong>Map Viewer support<\/strong><\/h3>\n<p>Some of the biggest enhancements to Parquet feature layers are in Map Viewer.
