🔓 New, more powerful Access Policies

Access Policies now allow you to control column- and row-level access to a Data Pool’s data. They provide a powerful way to govern how your applications, whether internal or customer-facing, access the data. You assign Access Policies to Propel Applications, giving each set of API credentials specific access to the data.

Learn more about the new Access Policies.

🔏 Dynamic Access Policies for multi-tenant applications

Multi-tenant SaaS or consumer applications have more specific data access control requirements. Each tenant should only access their own data, and the application must support potentially millions of unique tenants. Dynamic Access Policies allow you to pass policy values via a custom claim in the API access token. The policy values are cryptographically signed to the access token and used to evaluate the policy. This securely controls access to tenant data without the need to create a policy for each tenant, which could be cumbersome.

Learn more about the multi-tenant access controls.

Real-time updates for Webhook Data Pools

The Webhook Data Pool supports real-time updates. It unlocks advanced analytics use cases where you have to deal with late-arriving data that needs to be updated in the original record. Real-time updates have the additional benefit that you can safely retry requests without worrying about creating duplicates.

Read the real-time update docs to learn more.

🚦 New conditional aggregate functions for Custom Metrics: COUNT_IF, SUM_IF, and AVG_IF

These new functions enable you to define Metrics by aggregating records based on certain conditions.

Let’s say you want to calculate the Net Promoter Score (NPS), a common metric for customer satisfaction. NPS is calculated based on responses to a single question: “On a scale of 0-10, how likely are you to recommend our company/product/service to a friend or colleague?” Responses are classified as follows:

  • Promoters (score 9-10)
  • Passives (score 7-8)
  • Detractors (score 0-6)

NPS is then calculated by subtracting the percentage of customers who are Detractors from the percentage of customers who are Promoters.

Here’s how you can use COUNT_IF to calculate NPS:

(COUNT_IF(response >= 9) - COUNT_IF(response <= 6)) / COUNT() * 100

This will calculate the percentage of Promoters, subtract the percentage of Detractors, and multiply by 100 to give you the NPS score.

  • We improved the error messages that are shown when querying Data Pools and Metrics without the expected scope.
  • We now return a Bad Request Error if clients provide invalid time zones.
  • We added comparisons to Custom Metrics, and now expressions like SUM(foo > 1) or SUM(foo IS NOT NULL) are supported.
  • We added IS and IS NOT comparison operators to the custom expressions.

New features

  • 🎉 Self-serve sign-up is open! You can now sign up to Propel and get started without filling in a form or contacting us.

  • 🕸️ New Webhook Data Pool. This new Data Pool type allows for easy ingestion of JSON events into Propel. Webhook setup and management is available in both the console and via our GraphQL API. The console has a rich UX for easily building and testing your JSON schema to match the event structure. Check out the documentation.

  • 🌮 We have a new and improved Quickstart to get you going with sample data as fast as possible.

  • 💥 New Console navigation. We’ve streamlined the navigation and introduced the concept of Credentials for Data Pools. (For existing customers: Credentials replace the concept of Data Sources within the Console. No changes have been made to the public APIs.)

  • 🛝 New top-level API Playground! The API Playground used to be available inside each metric definition in the Console. We’ve moved it out into the main navigation, making it easier than ever to query your metrics.

  • New code samples in the API Playground. In addition to grabbing sample GraphQL code for your queries, you can now copy full cURL and JavaScript samples for making queries - right from inside the playground.

  • 👩🏽‍💻 UI Kit Code Examples. The UI Kit’s documentation in Storybook now has code examples for each component.

  • 📊 Added support for custom label formatting in the Leaderboard component in UI Kit. See the pull request.

​
Fixes

  • We fixed an issue when using MAX, MIN, FIRST, LAST, and ANY aggregate functions inside an arithmetic expression and their first argument is a JSON column. Expressions like MAX(foo.bar)/60 now work correctly.
  • We fixed a bug in the LAST aggregation function when the LAST function call was not a top-level operation in the expression.
  • We fixed issues with DATE formatting in some instances in Parquet files used in ingestion.
  • We fixed a navigation issue in the Console for users with smaller screens.
  • We fixed an issue with the navigation collapse arrow for the menu.
  • We fixed an issue with displaying a selectable timezone in the playground.

  • ⏰ Queries now support setting time zones. Learn more.
  • 💰 We updated pricing for the P1_X_SMALL propeller. See pricing.

​
Fixes

  • Time Series queries were sometimes returning unexpected numbers of granules (e.g., when passing timeZone). For example, asking for TODAY with granularity DAY should always return a single granule; asking for THIS_WEEK with granularity DAY should always return seven granules. This is now fixed.
  • Multiple S3-based files with the same name in different directories are now handled correctly.
  • Fixed a bug with wrong validations in the Leaderboard query builder in the Console, not allowing the query to execute.
  • Fix Metric overview documentation links in the Console.

​
Improvements

  • Syncs have a new processedRecords property. It is the sum of the existing properties newRecords, updatedRecords, and failedRecords. This is in support of the updating Data Pool functionality.
  • Better and more detailed errors for different Data Pool errors on creation and sync in the console and API.
  • Graphs in the Console now render using the browser timezone.
  • Customers can now more easily paste or type into all autocomplete components in the Console.
  • Setting a filter value in the Metric Playground will now provide autocomplete for less than 1000 values, and free text type in all cases.
  • New, better design for Applications listing page in Console with ID, scopes, and Propeller displayed.
  • The UI Kit now uses Luxon under the hood for better date handling.
  • On the docs, the Quickstart now introduces how to set up a Propel Application and use it in the Next.js starter app.
  • On the Leaderboards, Counter, Time Series, and Metric Report overview docs, we now use TacoSoft (our Quickstart data set) in all example queries.
  • On the Leaderboards, Counter, Time Series, and Metric Report docs, we updated query examples to use the up-to-date top-level query structure (metricName in query input instead of the deprecated metricByName or metricById).
  • We made visual improvements in the navbar on the docs site with higher contrast.
​
July

​
New features

  • 🌮 Customers are now able to create sample data with the new TacoSoft Data Source.
  • 🟣 New Console look and feel.
  • 💦 The UI Kit supports a new prop, refetchInterval, which can be used to specify how frequently a component should re-fetch new data.
  • 📦 We have simplified UI Kit and re-packaged it as a single, tree-shakeable NPM library, @propeldata/ui-kit.

​
Fixes

  • In the Metric Playground, we fixed an issue with the filter drop-downs not showing values. Customers can now select a unique value from the drop-down when using filters in the Playground.
  • Fixed an issue with unique name-checking. Customers will now see validation for every unique name in the console.
  • Fixed a bug in the Metric Report API where users could select dimensions not declared in any of the report’s Metrics. Now developers are only able to select dimensions specified in the Metrics.
  • Fixed a Counter Metric performance regression.
  • Fixed a corner case where new Data Pools were getting stuck in the “CREATED” state.
  • Fixed a bug where if a measure or dimension column in a Metric is JSON, we were not taking it into account as part of the available columns to be selected.
  • Fixed an issue with the calculation of query timeouts. Some queries were incorrectly timing out at 3 seconds when they should time out at 10 seconds.
  • Fixed a password reset bug.
  • Fixed an issue where we were missing time granules for certain relative time ranges.
  • The Amazon S3 Data Source now supports syncing larger S3 buckets, and will sync up to 1,000 files at a time.
  • Previously, S3 Data Sources could be created with invalid S3 bucket names, resulting in them getting stuck in a “CONNECTING” state. Now, when attempting to create or modify an S3 Data Source, setting bucket to an invalid S3 bucket name will result in synchronous failure with a BAD_REQUEST error message: “Invalid S3 bucket name; ensure you pass only the S3 bucket name and not its ARN or URL”.
  • Customers can now switch tables and see the updated schema when creating a Data Pool. Previously, the schema was not updated when switching tables.

​
Improvements

  • New homepage with a handy video!
  • In the Data Pool section of the Console, we have improved the Sync error messages for Snowflake and S3 Data Sources. Customers will now see a helpful message with the error details for failed Syncs in the Data Pool overview syncs table.
  • In the Metric definition, Metric settings, and Playground sections of the Console, the filter operators IS_NULL and IS_NOT_NULL are now available.
  • In the Data Pool section of the Console, the “Preview Data” table now loads faster and adjusts to the screen height. Additionally, the text in the cells of the table will not wrap, and an ellipsis will be displayed when the text is too long.
  • In the Data Pool section in Console, we updated Data Pool documentation links.
  • We have improved API error messages for our customers. Authentication and authorization-related errors and identifier parsing errors will no longer be returned as internal errors. Instead, we catch these errors and provide more informative error messages.
  • We have improved the handling of query errors by introducing a new error that specifically indicates when the Propeller is too small. If a Metric query exceeds the maximum execution time, customers will now receive a more informative error message. The message will indicate that the user needs a bigger Propeller instead of a generic error message such as “The query failed for an unknown reason.”
  • Data Pool Syncs are now created before attempting to connect to the underlying database, resulting in earlier visibility. Previously, if we failed to connect to a database, we did not create any Sync and kept retrying until successful. With the new process, we create failed Syncs that represent unsuccessful attempts, improving visibility for customers.
  • The Console now remembers the last environment a user accessed when switching between accounts.
  • The Console now remembers the last account and environment a user accessed when logging back in.
  • If a user has never logged in, the Console defaults to their most recently created account and its development environment.
​
June

​
New features

  • 😍 Support for Querying JSON data and JSON data type. Snowflake users can now sync their VARIANT, OBJECT, and ARRAY columns as JSON to Propel. Read the blog post
  • 🛠️ New data synchronization controls are now available for Snowflake. Read the blog post.
  • 🌮 You can now provision demo data for TacoSoft, our imaginary B2B SaaS taco-selling application. The demo data will make it easier to experience the full power of Propel.
  • 🤓 We introduced a new METRIC_READ scope, which enables developers to list metrics without requiring full ADMIN scope. This new scope allows Propel Applications to retrieve and list Metric resources within the Environment, without being able to query their data.
  • ⛔️ We added new IS_NULL and IS_NOT_NULL filter operators for Metric and query filters. The value field in FilterInput is now nullable. If the specified filter operator is IS_NULL or IS_NOT_NULL, then the value field is not required. Otherwise, the value field is required, and the request will be rejected if it is not present.

​
Fixes

  • Fix to allow modifying AND and OR Filters on Metrics.
  • Previously, a bug was triggered when customers provided an invalid Snowflake account, causing their Snowflake Data Source to become stuck in the “CONNECTING” state. This issue has now been fixed.
  • When creating a Data Pool, customers will be redirected to the correct link for tenant ID documentation.
  • When creating an Amazon S3-powered Data Pool, we now display the first empty sync instead of the “hang tight” graphic.

​
Improvements

  • The documentation site has new styles ✨.
  • In the Console, the input to create a new Amazon S3 Data Source table is now ”Unique Name”, instead of “Name”. It will show an error when the name is not unique within the Data Source context.
  • In the Console, during Data Pool creation, customers will not see cached data after leaving the creation flow and returning, but it will be kept within the Data Pool creation session.
  • The Terraform provider now supports creating MIN, MAX and AVERAGE Metrics. It supports setting the cursor and sync interval for Data Pools, creating and updating Policies, and it is smarter about when to replace versus update a changed resource.
​
May

​
Improvements

  • Metric Report: We increased the number of supported dimensions from 2 to 10.

  • Add support for Parquet data types: Map, List and Struct that are mapped to Propel column data type: JSON.
  • Add support for group structures within Parquet files.

​
Fixes

  • Fixed an issue with ingesting timestamps with a value of 0 and enhanced error handling for negative epoch timestamps.
  • Fixed an issue with WEEK granularity starting on a Sunday. The WEEK granularity now starts on Monday, consistent with LAST_N_WEEKS and the week-based relative time ranges.
  • Fixed a bug with changing between Relative and Absolute time in the metric playground.
  • Fixed a bug with the GraphQL variables when changing between relative types in the metric playground.
  • Fixed a bug where the username string in the top right of the web console would show the id instead of the username.
