Zoomdata version 2.6 Release Notes
These release notes cover changes and fixes made to Zoomdata rapid release version 2.6. You can identify your version at the Login screen.
With the release of Zoomdata version 2.6, we introduced a new model for feature and patch updates. Version 2.6 is a rapid release version that adds stability fixes and new functionality every four weeks. The latest updates are available in v2.6.3. For more information, see Managing Licensing for your Environment.
Zoomdata version 2.6.3
- Zoomdata now offers a command line interface (CLI) for developers to create custom charts in a development environment of their choice. The CLI is an alternative to the Chart Studio web-based interface and helps developers manage all aspects of custom charts created within your environment.
- You can now use non-Latin characters in expressions and calculations. To see what characters are supported, see Creating Calculations in Zoomdata.
- The Elasticsearch connector has been updated to support ES versions 5.6.x and 6.0.x
- The Spark version bundled with Zoomdata is upgraded to Spark version 2.2.1.
- Data sources public REST API was updated to v2 and the prior v1 public data sources API was deprecated. Note this change requires updates to client applications to pass in v2 content type header.
- Resolved a problem with the Lines Trend chart style where using calculated values on the Y axis of the chart cased the chart to not render properly.
- Fixed a bug related to the Raw Data Table chart style where HTML formatted strings were no longer automatically converted to hyperlinks within the chart.
- Addressed an issue with using the time transform calculation where applying a shifted timezone to a particular time field in the datasource resulted in charts that grouped by time to not properly display data for the timezone shift.
- Zoomdata’s Chart Studio is now deprecated. You can continue to make custom charts and carry out other developer tools using the new custom chart CLI. If you want to create custom charts in Chart Studio, a Supervisor can toggle it on.
Zoomdata Version 2.6.2
- You can now filter on metrics within your dataset, as well as previously created calculations. In addition, filtering capabilities have been split into filtering on datasource fields and filtering on metrics and calculations. Filtering on datasource fields are now referred to as row level filters and filtering on metrics/calculations are called group filters. For more information about using group filters, see Filtering data.
- Administrators can define the type of formatting for number sets within a dataset, which is done at the level of the data source. This allows for greater control over the formatting of decimal points, numeric units, and negative numbers. In addition, Administrators can now format the following:
- Plain number formats
- Computer storage units
- Scientific notation
- When defining the format of fields, Administrators can also set the required locale for groups of users/users to display the correct format for their geographical location. For more information, see Users and Groups.
- The Solr data connector in Zoomdata has been upgraded to include support for Solr 6.4+ and Solr 7 versions.
- When exporting chart data from visualizations from your environment, they are now exported in CSV file formats instead of Excel sheets format(.xls). For more information, see Exporting Charts and Dashboards.
- Improved tooltips for visualizations by updating the positioning and color indicator.
When upgrading from previous versions, the default port for Zoomdata has changed from 8443/HTTPS to 8080/HTTP. HTTPS can be configured using the steps in Configuring Zoomdata Property Files. In addition, prior releases of Zoomdata supported running both https and http simultaneously, this dual port configuration is no longer supported by Zoomdata but can be achieved using a proxy front ending Zoomdata.
- Resolved an issue with OAUTH token handling.
- Fixed a bug related to the Upload API where concurrent REST API requests were not supported and caused HTTP errors to be thrown.
- Addressed a problem with loading visualizations.
- Resolved a problem with previewing data for a CSV upload data source where different columns in preview mode were incorrectly shown as identical.
- Addressed a problem with color selection in visualizations where changing the color palette from gradient to distinct colors would not update the color scale.
- Fixed a bug related to Line & Bar and Floating Bubbles chart styles where in-visualization tooltips would not disappear after expanding the chart to full screen.
Resolved a problem with MongoDB Atlas where data collections were not retrieved after the initial connection.
- HATEOAS links are no longer provided with the public API endpoints.
- HTTP redirect has been deprecated.
Zoomdata Version 2.6.1
- Controls inside a dashboard widget are now responsive to widget size and are minimized when not needed. The toolbar controls are now only shown on the dashboard canvas when hovering over the widget. Also, dashboard widget controls and group/metric pickers collapse or disappear depending on the size of the widget.
- Zoomdata Administrators now receive earlier notifications about the status of the license expiration date for their environment. For more information about requesting a new license key, see Managing Licensing for your Environment.
- An SAP Hana connector is now available from Zoomdata (subject to license), which supports Row Level Calculations. For more information, see Managing your SAP Hana connectors.
- Added a REST API endpoint to programmatically create personal OAUTH tokens for use in embedded scenarios.
- Updated the public REST API for connections.
- Resolved an issue around calculations yielding null values where the null values were displayed on the color legend range, instead of including numeric values.
- Addressed a problem around the Raw Data Table chart type in data source configuration where modifying or removing and re-adding the index of the underlying data source would cause the chart to error out when trying to render.
- Fixed a bug related to upgrading metadata from version 2.3 to version 2.6.
Zoomdata version 2.6.0
Charts and Dashboards
- You can now create derived fields within calculations for your charts and dashboards. This allows you to build visualizations using both the fields in your data source and also derived values of your data to enrich your insights. You can use derived fields and row-level expressions as arguments or aggregation functions in calculations, allowing you to create advanced calculations. This functionality is supported on Impala and PostgreSQL. For steps and information, see Creating Calculations in Zoomdata.
- Dashboards have an improved chart layout, make the responsiveness faster and increasing the ease of interaction. The layout improvements also enables smaller sized chart widgets within a dashboard, meaning you can view more data at one time.
Server and Client Application
- Zoomdata now uses Apache Spark as its internal processing engine. For more information, see How Zoomdata uses Spark.
- The Query Engine is now a standalone service within the Zoomdata environment and offers its own deployment and configuration options. For more information about how Query Engine performs, see Managing your Query Engine.
- If you have an existing externalized Spark cluster, specifically Spark on Yarn on Cloudera clusters, you can use your existing cluster for use with Zoomdata.
- You can now leverage FluentD as a unified logging layer in conjunction with Zoomdata, meaning that you can direct your log files to a central repository using FluentD. For more information, see Setting up Unified Logging.
- The Upload API connector no longer requires MongoDB for data storage. Data for Upload API is now stored in PostgreSQL. For more information, see Using Upload API.
- The Flat File (CSV) upload functionality now utilizes PostgreSQL as a data store.
- Amazon S3 and HDFS data sources now use their own embedded Spark instance for data processing.
- The SparkIt capability for data sources is now fully removed and is no longer available.
- Amazon S3, HDFS, and MongoDB data sources are now migrated over to use Zoomdata's own microservice architecture.
Security and Account Management
- For users imported in to Zoomdata via SAML or LDAP, the auto-creation of groups that map to users existing groups is now configurable.
- Security scanning for your Zooomdata environment is improved.
- Custom visualizations can now be defined to use up to 10 group-bys within a chart.
- REST API to append data to an existing Upload data source is now supported.
Known Limitations and Issues
- Upload API and File Upload interpret values which include a currency symbol such as $10.00 as attributes (text), not as numbers.
- Upload API and File Upload do not calculate date and time properly when your PostgreSQL server is not in UTC time format.
- HDFS and S3 connectors have known limitations around grouping time fields that were converted from strings.
- Upload API and File Upload only support upload of individual files less than 200MB. For larger file sizes, split the files up into smaller files and add them incrementally to an existing File Upload source.
- Derived fields have the following limitations in 2.6.0:
- Play mode, Live mode, and data sharpening are not supported.
- Data profiling is not supported.
- Derived fields cannot be used on fusion sources made of Impala and PostgreSQL.
- The following chart types are not supported: Histogram, Boxplot, Percentile, and Last Value.
