This page lists the quotas that apply to Pub/Sub Lite.
Pub/Sub Lite enforces a limit of 1,000 Lite subscriptions per Lite topic. You cannot request an increase for the number of Lite subscriptions.
The following quotas apply to Pub/Sub Lite requests:
|Administrative read requests per min||600||Getting and listing Lite topics and Lite subscriptions|
|Administrative write requests per min||600||Creating, updating, and deleting Lite topics and Lite subscriptions, or acknowledging messages|
These quotas apply to each Google Cloud Console project and are shared across all applications and IP addresses using that project.
The following quotas apply to each zone:
|Publishing throughput per project||64 MiB/s|
|Subscribing throughput per project||128 MiB/s|
|Storage per project||10 TiB|
|Lite subscriptions per Lite topic||1000|
Lite topics store messages in partitions, and each message uses 256 bytes-1 MiB of storage. If the message is larger than 256 bytes, then the size of the message is the sum of the following:
- The number of bytes in the encoded message body string
- The number of bytes in the key and value of each attribute
- The number of bytes in the ordering key
- 12 bytes for the event timestamp
For more information about the message format, see the message resource in the Pub/Sub Lite API reference.
If you want to increase any of your quotas for Pub/Sub Lite, you can use the Google Cloud Console to request a quota increase. For details, see Requesting higher quota.
