Expanded SQL function support

We have significantly expanded our SQL function support, extending it to a broad range of functions for PostgreSQL and ClickHouse SQL dialects, as well as unique Propel functions. This improvement offers developers greater flexibility and control when querying, transforming, and managing data.

Learn more about Propel SQL function support.

New Console Navigation

We’ve rolled out an updated Console navigation. The new menu structure and design organizes the Console into two primary sections: “Data” and “API”. The “Data” section houses all Serverless ClickHouse-related functionalities, and “API” contains all API-related functionalities.

Log in to the Console to see the new navigation.

GraphQL Schema Explorer

We introduced a GraphQL Schema Explorer in the Console. Developers can now actively search through the Propel API GraphQL schema, access API endpoints with ease, and directly download the schema from a provided URL.

Check out the new GraphQL Schema Explorer in the Console.

A screenshot of Propel's GraphQL Schema Explorer



  • We resolved an issue with the S3 Data Pool that caused a persistent “CONNECTING” state when customers used an “s3://” or “https://” prefix in the URL for their table path, rather than a relative path within the bucket. Now, if the provided “s3://” or “https://” URL points to the named bucket, the URL’s path is used as the relative path into the bucket. Invalid table paths provided by the customer will now be synchronously rejected.


  • We fixed the SQL Console to respect the Propeller selection.
  • We fixed the GraphQL Playground to respect the Propeller selection.
  • When creating a Data Pool, we fixed the case when a timestamp is not selected.
  • In the API Playground, we fixed leaderboard dimensions clearing for ClickHouse Data Pools.
  • In the API Playground, we fixed the leaderboard table view width and height.
  • In the API Playground, we fixed the time dimension not pre-populating.
  • In the SQL Console, we fixed result cell wrapping.
  • Data Pools created by Materialized Views now see the "Operations" tab.



  • The SQL interface now properly handles identifier quoting.
  • We now support CASE statements in SQL.



  • The API Playground will now populate filter values using the Top Values API.
  • The API Playground now includes an “All time” option for the relative time range.
  • The API Playground has a new layout for TimeSeries, Counter, and Leaderboard APIs.
  • The API Playground now supports setting a “Time Dimension” that is different from the Data Pool’s default timestamp.
  • The API Playground will now show the Data Pool selection first.
  • The API Playground will now only show the “Existing Metrics” for the selected Data Pool.
  • The SQL Console has a new improved layout.
  • The SQL Console has new improved SQL syntax validation.
  • The SQL Console will now show long result values in a tooltip when they are trimmed.
  • The Data Pool list page will not break if the sync activity query fails.
  • When creating and updating Amazon S3 credentials, the path and bucket will be trimmed to prevent white spaces from being accidentally entered.

New features


You can now query any Data Pool using SQL over the GraphQL API. Need to join, group by, or perform complex queries? No problem. Propel's SQL supports PostgreSQL syntax, including joins, unions, and common table expressions for more complex queries. The SQL API allows you to query your data however you'd like, and Propel's multi-tenant access policies ensure that customers can only query their own data.

Propel's SQL API

Learn more about the SQL API.

🐘 PostgreSQL-compatible SQL interface

You can now connect any BI tool or PostgreSQL client to Propel. Essentially, Propel mimics a PostgreSQL instance, providing a seamless connection to a variety of tools or client applications.

For SaaS applications, this simplifies the process of providing a customer-facing SQL interface for custom reporting and data sharing.

Propel's SQL interface

Learn more about the SQL interface.

🗄️ Data Grid API

The new Data Grid API efficiently retrieves individual records from a Data Pool, with the added convenience of built-in pagination, filtering, and sorting. It's perfect for displaying data in a table format, making it ideal for data tables with individual events, orders, requests, or log messages.

Propel's Data Grid API use cases

🧠 OpenAI integration

Propel’s OpenAI integration lets you easily collect OpenAI ChatGPT API usage events from your application. Once the events are in the Data Pool, you can use them to power usage metering, customer-facing dashboards, reports, and data-driven workflows.

Learn more about the OpenAI integration.

🔓 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.

Learn more about defining Custom Metrics.

  • 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 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.

  • 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.

  • ⛔️ 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.


  • 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.


  • 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.
