Introducing Aggregations in Fabric API for GraphQL: Query Smarter, Not Harder
Summarize, group, and explore data in one step with the new GraphQL aggregations feature
We’re excited to launch a powerful new capability in the Fabric API for GraphQL—Aggregations. This feature brings native support for summary-level insights directly into your GraphQL queries, making your data exploration faster, simpler, and more efficient.
Why Aggregations?
Until now, getting summary metrics like totals, averages, or counts required workarounds—either writing custom logic or running multiple queries and doing the math client-side. Aggregations change that.
Now you can:
- Query KPIs and summary values directly from your API.
- Use filtering, slicing, and grouping with the new group by argument.
- Build dashboards and apps that load faster with fewer queries.
The new aggregation operations include:
- count – Count of records (or non-null values of a field) in the group.
- sum – Sum of all values in a numeric field.
- avg – Average (mean) of values in a numeric field.
- min – Minimum value in a field.
- max – Maximum value in a field.
How It Works
With Aggregations, you can use the new groupBy argument on a queryable field to group data and apply functions like sum, avg, and count in a single query.
Example 1: Total Products by Category
query {
products {
groupBy(fields: [category_id])
{
fields {
category_id # grouped key values
}
aggregations {
count(field: id) # count of products in each group (count of "id")
}
}
}
}
This returns aggregated results grouped by category, similar to what you might see in a pivot table.
{
"data": {
"products": {
"groupBy": [
{
"fields": {
"category_id": 1
},
"aggregations": {
"count": 3
}
},
{
"fields": {
"category_id": 2
},
"aggregations": {
"count": 2
}
},
...
]
}
}
}
Example 2: Calculate sum of prices and average ratings
query {
products {
groupBy(fields: [category_id])
{
fields {
category_id
}
aggregations {
count(field: id) # number of products in the category
sum(field: price) # total of all product prices in the category
avg(field: rating) # average rating of products in the category
}
}
}
}
In addition to counting, you can also calculate sums and averages for different fields group by product categories:
{
"data": {
"products": {
"groupBy": [
{
"fields": {
"category_id": 1
},
"aggregations": {
"count": 3,
"sum": 2058.98,
"avg": 4
}
},
{
"fields": {
"category_id": 2
},
"aggregations": {
"count": 2,
"sum": 109.94,
"avg": 4
}
},
...
]
}
}
}
Built for Simplicity and Scale
Just like the rest of Fabric API for GraphQL, Aggregations are strongly typed and schema-aware. You get discoverable field names and backend query optimizations — all with the flexibility of GraphQL.
