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 do not currently support scheduled reloading of raw data, they must manually be refreshed using the refresh fields button in datasource fields screen.
- 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.
