What is the maximum memory a Google App Engine app may consume?

What is the maximum amount of local memory (not Memcache) each instance of a Google App engine app is allowed to consume?

I couldn't find any information on the GAE quotas page.

Solution

  • The maximum memory limit for an App Engine instance depends on the instance class that you choose. The default limit is 128 MB. The following classes are currently available:

    • F1 and B1 - 128 MB
    • F2 and B2 - 256 MB
    • F4 and B4 - 512 MB
    • F4_1G, B4_1G - 1024 MB

    Edit: Second generation instances have double the memory:

    • F1 and B1 - 256 MB
    • F2 and B2 - 512 MB
    • F4 and B4 - 1024 MB
    • F4_HIGHMEM and B4_HIGHMEM - 2048 MB
    • B8 - 2048 MB
