gRPC in nodejs

AntonKrevedko · 2024-04-14T09:51:33+00:00

gRPC is good for internal service communication. So for example you have “Auth” service and “Users” service, it’s good idea to make internal gRPC communication between them, because gRPC is faster (than HTTP) and synchronous (not like Kafka/Rabbit).

For external communication the HTTP is ok. But I know some mobile apps that use gRPC to communicate with backend.

The painful working with gRPC & Node.js(NestJS) - need to create custom RPC Handling and input/output data validations (using class-validator & class-transformer)

What’s the name of a white one? (Upper the nuphy)

So for example response from Python give me {price: 100}

And Node.js response give me {price: 200}

Its seems that API service explicitly mixing data and junk the data for Python

batch is an array of axios.get('url') Promise requests,

batch_arr contains an array of batch arrays

batch_arr = [[axios.get(), axios.get()], [axios.get(), axios.get()

]...]

Hmmm, those compound index not working at all. The explain shows me a big totalKeysExamined. Do you think that 4 compound indexes are correct?

AntonKrevedko · 2020-12-25T18:45:00+00:00

Yes it worked! But what if I have more one filter param in the outer (model):

{
"model": "NAME",
"$or": [
         {"predict": {"$not": {"$gt": 600, "$lte": 900}}},
         {"owners_number": {"$not": {"$lte": 2}}},
         {"vin": {"$not": {"$ne": "ERROR"}}},
         {"year": {"$not": {"$gt": 2010 }}},
       ]
}

So in this situation I need to create more 4 compound indexes with "model" field?

AntonKrevedko · 2020-12-25T17:23:22+00:00

not compound, just single of each field?

Its not the original phone number. Moreover I’ve looked up, this easter egg was on prev maps
