Rebuilding the model all the time causes memory issues

[32bit]

I have a situation where my collection name is embedded with the Model creation. This is because we have a versioning process to change collection names at runtime, the model remains the same.

const mymodel = mongoose.model('TestModel', TestSchema, collectionName);

In production we noted that there was a large footprint to this- a very large number of models are in memory.

Is there a way to compile this once and reset the collectionname when it changes instead of doing that all the time?

Not currently. You should be able to reduce the memory usage by deleting the model before creating a new one.

mongoose.deleteModel('TestModel');
const mymodel = mongoose.model('TestModel', TestSchema, collectionName);
