Enhancements and Fixed Issues in ThingWorx Platform 9.3.3
The following enhancements are part of ThingWorx Platform 9.3.3.
Improvements To StreamEntryProcessor
The StreamEntryProcessor uses one lock for all access to the queue, and holds the thread conditionally when the queue is full. This would create a backpressure on the underlying queues, causing one or more of the following:
ThingWorx Platform would get very slow to respond and some parts of the functionality would get into frozen state.
The persistent property queue size would not change
Event queue and/or WSExecution would start to overflow up
Devices would start to go offline.
In the thread dump, you could see lots of threads waiting on socket read, or threads waiting on other threads holding locks.
The only way out of this state is to restart ThingWorx.
Added a generic JDBC persistence provider package to enable users and extensions to create a persistence provider targeting an external database. For more information, see Connecting to an External Database.
Mashup Builder
User Interface
The area below the canvas is now a collapsible dock that you can drag other panels to. By default, the dock contains the Bindings and Reminders panels.
Added a new dialog box that enables you to set values for the Margin properties.

Added properties that enable you define outer margins for containers
Added properties that enable you to customize the tab icon when a container is configured to expand and collapse.

Known Issues and Limitations
The following items are known issues and are scheduled to be fixed in a future release.
Tracking Number
When a project has more than 500 entities, modify one of the entities and the entities beyond the 500 count get assigned to the PTCDefaultProject.
When using Grid Advanced inside a modal popup, closing the modal popup is increasing the memory heap.
In previous versions of ThingWorx, the Width and Height properties of the Image widget were incorrectly displayed when an image is expanded to fill a container. Specifying a fixed width or height for images that are expanded to fill a container may cause scaling issues when migrating to ThingWorx 9.3.3. The issue may occur depending on the original image dimensions, the image height or width ratio relative to the container, the selected scaling option, and the size of the container. To fix this issue, you must adjust the image scaling manually after upgrading.
When resizing a column to be very narrow, the grid is distorted and data is shown in a single column.
When the “Text“ property of ptcs-textfield or ptcs-textarea is bound to an “Entity Name“ of Dynamic Thing Template, the data bindings are lost when reloading the page.
Cells in a collection widget can not be clicked via touch on iPad.
Services with input type JSON do not work as expected during runtime in mashups.
