· 2 min read
Materialized Views are now available in StackQL. Materialized Views can be used to improve performance for dependent or repetetive queries within StackQL provisioning or analytics routines.
Refresher on Materialized Views
Unlike standard views that provide a virtual representation of data, a Materialized View physically stores the result set of a query. This implies that the data is pre-computed and stored, which can lead to performance gains as the data doesn't need to be fetched from the underlying resource(s) every time it is queried.
Benefits of Materialized Views in StackQL
Performance Boost: With data already stored and readily available, Materialized Views can substantially reduce StackQL query execution time, especially for complex and frequently-run queries.
Data Consistency: Since Materialized Views provide a snapshot of the data at a specific point in time, it ensures consistent data is returned every time it is accessed until it is refreshed.
Flexibility: You have the flexibility to refresh the Materialized View as needed usign the
REFRESH MATERIALIZED VIEWlifecycle operation in StackQL. This is particularly useful when working with rapidly changing data.
Using Materialized Views in StackQL
Here's a step-by-step guide on how you to use this new feature in StackQL:
- Create a Materialized View:
CREATE MATERIALIZED VIEW vw_ec2_instance_types AS
SELECT
memoryInfo,
hypervisor,
autoRecoverySupported,
instanceType,
SPLIT_PART(processorInfo, '\n', 3) as processorArch,
currentGeneration,
freeTierEligible,
hibernationSupported,
SPLIT_PART(vCpuInfo, '\n', 2) as vCPUs,
bareMetal,
burstablePerformanceSupported,
dedicatedHostsSupported
FROM aws.ec2.instance_types
WHERE region = 'us-east-1';
- Refresh the Materialized View:
REFRESH MATERIALIZED VIEW vw_ec2_instance_types;
- Use the Materialized View in a StackQL Query:
SELECT
i.instanceId,
i.instanceType,
it.vCPUs,
it.memoryInfo
FROM aws.ec2.instances i
INNER JOIN vw_ec2_instance_types it
ON i.instanceType = it.instanceType
WHERE i.region = 'us-east-1';
- Drop the Materialized View:
DROP MATERIALIZED VIEW vw_ec2_instance_types;
More information on Materialized Views in StackQL can be found here.
Introducing Table Valued Functions in StackQL
· 2 min read
Many provider query responses include columns which are arrays, the iam policy related resources in google are a classic example of this. for example, this query:
select *
from google.cloudresourcemanager.projects_iam_policies
where projectsId = 'stackql';
produces..
|-----------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|--------------|
| condition | members | role |
|-----------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|--------------|
| null | ["serviceAccount:1234567890-compute@developer.gserviceaccount.com","serviceAccount:1234567890@cloudservices.gserviceaccount.com","serviceAccount:stackql@appspot.gserviceaccount.com"] | roles/editor |
|-----------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|--------------|
| null | ["serviceAccount:1234567890-compute@developer.gserviceaccount.com","serviceAccount:1234567890@cloudservices.gserviceaccount.com","serviceAccount:stackql@appspot.gserviceaccount.com"] | roles/editor |
|-----------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|--------------|
| null | ["serviceAccount:1234567890-compute@developer.gserviceaccount.com","serviceAccount:1234567890@cloudservices.gserviceaccount.com","serviceAccount:stackql@appspot.gserviceaccount.com"] | roles/editor |
|-----------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|--------------|
What you want to do is unnest each member in members for each role binding (and condition if applicable)
Enter the table valued function json_each.
The json_each function accepts a field (optionally with a json path expression) and returns a table object with fields that can be projected in your result set, for example (querying the same underlying resource as above), this...
select
iam.role,
SPLIT_PART(json_each.value, ':', 1) as member_type,
SPLIT_PART(json_each.value, ':', 2) as member
from google.cloudresourcemanager.projects_iam_policies iam, json_each(members)
where projectsId = 'stackql';
now provides something much more useful from an analytic perspective:

Query and Manage Google Workspace Users and Groups with StackQL
· 3 min read
info
stackql is a dev tool that allows you to query, manage, and perform analytics against cloud and SaaS resources in real time using SQL, which developers and analysts can use for CSPM, assurance, user access management reporting, IaC, XOps and more.
The googleadmin StackQL provider is now available, which allows you to query, provision, or manage Google Workspace users, groups, devices, and more using StackQL. The googleadmin provider can be used with the google provider or other cloud providers to generate entitlements reports (or user access reviews) where Google Workspace identites are used in identity federation or IAM bindings.
The full documentation on how to use a Google service account for authentication to the googleadmin provider is available here. Information about the directory resources available and their fields and methods, is available in the StackQL Provider Registry Docs.
Simple Query
A simple query using the googleadmin provider is shown here:
SELECT
primaryEmail,
lastLoginTime
FROM
googleadmin.directory.users
WHERE domain = 'stackql.io'
AND primaryEmail = 'javen@stackql.io';
which would return the following results...
|------------------|--------------------------|
| primaryEmail | lastLoginTime |
|------------------|--------------------------|
| javen@stackql.io | 2023-07-08T23:30:31.000Z |
|------------------|--------------------------|
Example Query Using Built-In Functions
Here is an example using built-in functions in StackQL (more information about built-in functions is available in the StackQL docs):
SELECT
primaryEmail,
json_extract(name, '$.fullName') as full_name,
lastLoginTime
FROM
googleadmin.directory.users
WHERE domain = 'stackql.io'
AND primaryEmail = 'javen@stackql.io';
which would return results like this...
|------------------|--------------|--------------------------|
| primaryEmail | full_name | lastLoginTime |
|------------------|--------------|--------------------------|
| javen@stackql.io | Jeffrey Aven | 2023-07-08T23:30:31.000Z |
|------------------|--------------|--------------------------|
Example Query Using Aggregate Functions
Here is an example of a summary query that could be useful:
SELECT
isAdmin,
COUNT(*) as num_admins
FROM
googleadmin.directory.users
WHERE domain = 'stackql.io'
GROUP BY isAdmin
results in...
|---------|------------|
| isAdmin | num_admins |
|---------|------------|
| false | 9 |
|---------|------------|
| true | 2 |
|---------|------------|
Entitlements Report Using a LEFT JOIN with the google provider
Using the LEFT OUTER JOIN capability with StackQL, you can generate entitlements or user access management reports that span across Google Workspace as an Identity Provider (IdP) and a Google Cloud resource (including Organizations, Folders, Projects, and resources), such as:
SELECT
split_part(json_extract(iam.members,'$[0]'), ':', 2) as member,
iam.role as role,
users.lastLoginTime
FROM google.cloudresourcemanager.organizations_iam_bindings iam
LEFT OUTER JOIN googleadmin.directory.users users
ON split_part(json_extract(iam.members,'$[0]'), ':', 2) = users.primaryEmail
WHERE users.domain = 'stackql.io'
AND iam.organizationsId = 141318256085
AND users.primaryEmail = 'javen@stackql.io';
which would return...
|------------------|------------------------------|--------------------------|
| member | role | lastLoginTime |
|------------------|------------------------------|--------------------------|
| javen@stackql.io | roles/bigquery.resourceAdmin | 2023-07-08T23:30:31.000Z |
|------------------|------------------------------|--------------------------|
| javen@stackql.io | roles/logging.admin | 2023-07-08T23:30:31.000Z |
|------------------|------------------------------|--------------------------|

Support for Outer Joins Released for StackQL
· 3 min read
info
stackql is a dev tool that allows you to query, manage, and perform analytics against cloud and SaaS resources in real time using SQL, which developers and analysts can use for CSPM, assurance, user access management reporting, IaC, XOps and more.
We are pleased to announce the addition of support for OUTER JOIN operations in StackQL queries. This is a significant addition to the language, and we are excited to see what our users will do with it!
info
An OUTER JOIN is a type of JOIN operation that returns all records from one table (or StackQL resource) and only those records from a second table or resource where the joined fields are equal (i.e. the JOIN condition is met). If there is no match, the missing side of the JOIN is filled with NULL values.
OUTER JOIN operations are important because they allow you to combine data from two or more resources (within a StackQL provider or across StackQL providers), even when there is no match between the two resources. This is a common scenario when performing analytics and reporting on user access management (for example between an IdP (like Okta) and a resource provider like AWS or Google).
Using OUTER JOIN operations in StackQL
If you wanted to find all users in your AWS account that have not logged in to their account in the last 20 days, and compare that to the same information for users in your Google Workspace account, you could use an OUTER JOIN operation to do this. The following query:
select
aws_users.UserName as aws_user_name
,aws_users.PasswordLastUsed as aws_last_Login_time
,CASE
WHEN aws_users.PasswordLastUsed = '' then 'false'
WHEN ( strftime('%Y-%m-%d %H:%M:%SZ', aws_users.PasswordLastUsed) > ( datetime('now', '-20 days' ) ) ) then 'true'
else 'false' end as aws_is_active
,json_extract(google_users.name, '$.fullName') as google_user_name
,google_users.lastLoginTime as google_last_Login_time
,CASE
WHEN google_users.lastLoginTime is null then 'false'
WHEN google_users.lastLoginTime = '' then 'false'
WHEN ( strftime('%Y-%m-%d %H:%M:%SZ', google_users.lastLoginTime) > ( datetime('now', '-20 days' ) ) ) then 'true'
else 'false' end as google_is_active
from
aws.iam.users aws_users
LEFT OUTER JOIN
googleadmin.directory.users google_users
ON lower(substr(aws_users.UserName, 1, 5)) = lower(substr(json_extract(google_users.name, '$.fullName'), 1, 5))
WHERE aws_users.region = 'us-east-1' AND google_users.domain = 'stackql.io'
;
would produce a result like this:
|------------------------|----------------------|---------------|------------------|--------------------------|------------------|
| aws_user_name | aws_last_Login_time | aws_is_active | google_user_name | google_last_Login_time | google_is_active |
|------------------------|----------------------|---------------|------------------|--------------------------|------------------|
| demo-stackql-cicd-user | null | false | null | null | false |
|------------------------|----------------------|---------------|------------------|--------------------------|------------------|
| github_actions | null | false | null | null | false |
|------------------------|----------------------|---------------|------------------|--------------------------|------------------|
| jeffrey.aven | 2023-06-30T04:29:14Z | true | null | null | false |
|------------------------|----------------------|---------------|------------------|--------------------------|------------------|
| kieran.rimmer | 2023-06-03T08:40:49Z | false | Kieran Rimmer | 2023-06-23T06:01:46.000Z | true |

| ... | ... | ... | ... | ... | ... |
|------------------------|----------------------|---------------|------------------|--------------------------|------------------|
Currently only LEFT OUTER JOIN sppport is available, but we will be adding support for RIGHT OUTER JOIN and FULL OUTER JOIN in the near future. Stay tuned!
