Managed Service for Apache Spark quotas

Managed Service for Apache Spark has API quota limits that are enforced at the project and region level. The quotas reset every sixty seconds (one-minute).

Handling Managed Service for Apache Spark Quota Errors: If you exceed a Managed Service for Apache Spark quota limit, a RESOURCE_EXHAUSTED (HTTP code 429) is generated, and the corresponding Managed Service for Apache Spark API request will fail. However, since your project's Managed Service for Apache Spark quota is refreshed every sixty seconds, you can retry your request after one minute has elapsed following the failure.

The following table lists the specific and default per-project Managed Service for Apache Spark API quota types, quota limits, and the methods to which they apply.

Quota Type	Limit	API Methods or Description
ClusterOperationRequestsPerMinutePerProjectPerRegion	200	CancelOperation (cancelling batch operation quota is shared with cancelling cluster operation quota).
BatchOperationRequestsPerMinutePerProjectPerRegion	200	CreateBatch, DeleteBatch
SessionOperationRequestsPerMinutePerProjectPerRegion	200	CreateSession, DeleteSession, TerminateSession
DefaultRequestsPerMinutePerProjectPerRegion	7500	GetBatch, ListBatches, GetSession, ListSessions
ActiveOperationsPerProjectPerRegion	5000	Limit on the total number of concurrent active operations of all types in a project in a region.

Increasing Resource Quota Limits: Open the Google Cloud IAM & Admin Quotas page, and select the resources you want to modify. Then click Edit Quotas at the top of the page to start the quota increase process. If the resources you are trying to increase aren't displayed on the page and the current filtering is "Quotas with usage," change the filtering to "All quotas" by toggling the "Quota type" dropdown.

Other Google Cloud quotas

Managed Service for Apache Spark batches utilize other Google Cloud products. These products have project-level quotas, which include quotas that apply to Managed Service for Apache Spark use. Some services are required to use Managed Service for Apache Spark, such as Compute Engine and Cloud Storage. Other services, such as BigQuery and Bigtable, can optionally be used with Managed Service for Apache Spark.

Required services

The following services, which enforce quota limits, are required to create Managed Service for Apache Spark batches.

Compute Engine

Managed Service for Apache Spark batches consume the following Compute Engine resource quotas:

Compute Tier	Quota
Standard	CPUS
Premium	N2_CPUS
Disk Tier	Quota
Standard	DISKS_TOTAL_GB
Premium	LOCAL_SSD_TOTAL_GB_PER_VM_FAMILY with N2 VM Family
GPU accelerator	Quota
L4	NVIDIA_L4_GPUS
A100 40GB	NVIDIA_A100_GPUS
A100 80GB	NVIDIA_A100_80GB_GPUS

The Compute Engine quotas are split into regional and global limits. These limits apply to batches you create. For example, to run a Spark batch with 4 driver cores (spark.driver.cores=4) and two executors with 4 cores each (spark.executor.cores=4), you will use 12 virtual CPUs (4 * 3). This batch usage will count against the regional quota limit of 24 virtual CPUs.

Free trial quotas: If you use the Compute Engine free trial, your project will have a limit of 8 CPUs. To increase this limit, you must enable billing on the project.

Default batch resources

When you create a batch with default settings, the following Compute Engine resources are used:

Item	Resources used
Virtual CPUs	12
Virtual Machine (VM) Instances	3
Persistent disk	1200 GiB

Cloud Logging

Managed Service for Apache Spark saves batch output and logs in Cloud Logging. The Cloud Logging quota applies to your Managed Service for Apache Spark batches.

Optional services

The following services, which have quota limits, can optionally be used with Managed Service for Apache Spark batches.

BigQuery

When reading or writing data into BigQuery, the BigQuery quota applies.

Bigtable

When reading or writing data into Bigtable, the Bigtable quota applies.

Identify workloads with quota or IP address limitations

You can use the following Cloud Logging queries to identify Managed Service for Apache Spark workloads that reached your quota or were unable to scale due to IP address exhaustion.

Quota query:

jsonPayload.@type="type.googleapis.com/google.cloud.dataproc.logging.AutoscalerLog"
jsonPayload.recommendation.outputs.constraintsReached="SCALING_CAPPED_DUE_TO_LACK_OF_QUOTA"

IP address exhaustion query:

jsonPayload.@type="type.googleapis.com/google.cloud.dataproc.logging.AutoscalerLog"
jsonPayload.status.details =~".*Insufficient free IP addresses.*"
