Release Notes

Check here for details of our releases (both historic and upcoming)

Upcoming Features for Releases in 2023​

New data type - Events​

Events are data that happened at a point in time for an amount of time, such as power station outages. We allow capturing these events and creating dynamic timeseries and curves from them.

New data type - Matrix​

Added support for storing matrices for various statistical uses, e.g. correlation and covariance matrices. Added support for converting timeseries and curves into matrices

New service - Reports​

New custom report functionality using custom ODSL code to generate any shape data to be presented in a report. Reports can be formatted using Mustache which is a popular HTML templating syntax.

Granular Security Policies​

Support for more granular security policies which can filter down to an individual document.

Correlation and covariance matrix functions​

Add function to calculate correlation and covariance matrices.

Improvements to searching​

Added more ways to perform searching for data

ODSL language improvements​

  • Added publish command to publish data to other tenants
  • Added sendmail command to send data as an email
  • Added set credentials command to store custom source user credentials
  • Added element-wise multiply and divide operators for matrices
  • Added single line if statements and conditional expressions
  • Improved type creation, adding support for bespoke error messages
  • Extended run command to support running reports

Release History​

2022
#### Smart Data on Types We add the ability to define smart timeseries and curves on a type. All objects that directly implement the type will have those smart data objects dynamically added.

User Tasks​

User tasks are manual tasks assigned to users either by other users or by processes such as data quality. Tasks can be:

  • Emailed
  • Pushed to JIRA

More Statistics Functions​

We will be adding for statistical functions for Timeseries and Curves.

More Statistics Functions​

We have added a few more functions that can be used in your ODSL scripts:

  • csum - Cumulative Sum
  • cmax - Cumulative Maximum
  • cmin - Cumulative Minimum
  • cave - Cumulative Average

Calendar improvements​

Improvements to the Intraday calendars:

  • Add timezone
  • Add a flag to indicate that it is an intraday calendar

Bulk updates and deletes​

Add support for performing bulk updates and deletes

Added community version​

Added FREE community version of the ODSL VSCode editor.

Quality Checks on Objects​

Added support for defining constraints (checks) on an object type, and also defaults for null values

Aggregation Framework in the ODSL Language​

Added language support for defining aggregations and aggregation stages.

Custom MongoDB Collections​

We have added support for clients to connect to your own MongoDB clusters and use the tools directly on the collections holding your own data.

Data Packages​

Data packages are pre-defined processes that users can deploy to their own environment to load data from providers into their private database. These data providers do not provide data that we can freely distribute, therefore the client has to load the data into their own private environment.

Events​

Events are a thing that has happened at a point in time, similar to an observation in a TimeSeries only with a lot more information. Example events are:

  • An order placed with a broker, exchange etc.
  • A trade made with a broker, exchange etc.
  • A planned or unplanned outage (REMIT Urgent Market Message)

Curve Change Values​

Added a 'change' value to show the absolute change of all tenors in a curve from the previous built curve

Region support in ODSL code​

Allow users to create regions in ODSL code to break a script up into smaller sections. These regions can be folded and run/debugged independently

Date Rule Grammar​

Added support for using dynamic dates such as T-1W (go back 1 week)

Support for unit conversion custom factors​

You can now add properties on TimeSeries or Curves to provide absolute conversion factors to a specified unit

Curve Building Support​

We added support for creating your own forward curves using logic created in OpenDataDSL scripts. You can create an object of type #CurveConfig with 1 or more inputs and 1 or more outputs and save to the new CURVE service, example configuration:

MY_CURVE = object as #CurveConfig
    name = "My Curve"
    expiryCalendar = "REOMHENG"
    buildScript = "simplecurve"
    inputs\[0\] = object as #CurveConfigInput
        key = "PRIMARY"
        id = "#MATBAROFEX.ROS.SOJA.FUT:CLOSE"
        required = true
    end
    outputs\[0\] = object as #CurveConfigOutput
        name = "CURVE"
        code = "multiplyByFactor(PRIMARY, factor)"
        factor = 1.5
        currency = "EUR"
        units = "MWH"
        expiryCalendar = "REOMHENG"
    end
end
save ${curve:MY_CURVE}

Data aggregation support​

Added the ability to filter, group and aggregate any data using ODSL and the REST services, e.g.

summary = aggregate ${exec}
    match service="ETL"
    group _id="$status", qty=count()
    sort qty desc
end

Add range support for time-series​

Add _range query option to specify a date range for time-series retrieval. Add 3 methods:

  • last(n) - last n observations
  • from(d) - from date d to the latest
  • between(d1, d2) - between 2 dates, d1 and d2

Object and data storage​

Improvements to the way objects and data is stored to allow greater query flexibility. Users can now query across all types of objects.

Custom save and delete reasons​

Added the ability to define a ‘reason’ on all save and delete methods. This reason is placed in the audit log and the saved object (if versioned)

Search object properties and return data​

Added the ability to query object properties, but return data entities using the profile command, e.g.

// Fetch all data for all ECB_FX currencies data = find profile SPOT from ${currency:public} where source == "ECB_FX"

Process Executions in the web portal​

Added the ability to view process executions in the web portal:

Indexes​
