1 MB limit in Google App Engine

In addition to the limit of '123' (no more than 1000 records can be returned for query), we found that gae has a limit of '1m.
I encountered a memoryerror when using memcache to cache a large list. The error message indicates that a cached item cannot exceed bytes. I ran to the group and asked. aral also encountered the same problem. in addition to memcache, Gae has a 1 m limitation in many places (the following is translated from the Aral blog ):

1. A Data Structure cannot exceed 1 m; otherwise, a memoryerror is thrown.
2. Response cannot return content larger than 1 MB; otherwise, an exception will be thrown: 'ttp response was too large'
3. A model instance (equivalent to a database record) cannot exceed 1 MB; otherwise, a requesttoolarge exception will occur. (I have encountered this exception)

Prateek added a limit of 1 MB for the image API in the reply; Google may not wantProgramMember BTCodeDrag the server down. from.. Net GC running principle also understand that frequent creation of large objects with a short life cycle will affect program performance. in. net, the standard is 85000 bytes. objects larger than this standard are allocated in a dedicated heap and are regarded as the second generation. therefore, either the memory is not recycled, or the second generation of objects are frequently collected.
