Did you know you can use jsonSchema in MongoDB to search for documents?

Let's say you have users collection with data below:

{ "_id" : ObjectId("5f64bd1eca8806f2c04fcbe3"), "customer_id" : 100, "username" : "john" }
{ "_id" : ObjectId("5f64bd1eca8806f2c04fcbe5"), "customer_id" : 206, "username" : "new_customer" }
{ "_id" : ObjectId("60420df441558d6671cf54f2"), "customer_id" : "123", "username" : "Ali" }

Now let's say you want to find all documents that has a customer_id of type string instead of int.
In Mongo shell:

let ms = {required: ["customer_id"], properties: {customer_id: {bsonType: "string"}}}

This schema says look for documents that have customer_id field with string type. To search:

> db.customers.find({$jsonSchema: ms})
{ "_id" : ObjectId("60420df441558d6671cf54f2"), "customer_id" : "123", "username" : "Ali" }

Interesting, right? :)

One of the issues you always face with postgres on new systems is pg_config error. If you don't want to install postgres and willing to have postgres library in Pytho operational:

1. brew install libpq
2. xcode-select --install
3. echo 'export PATH="/usr/local/opt/libpq/bin:$PATH"' >> ~/.zshrc
4. env LDFLAGS="-I/usr/local/opt/openssl/include -L/usr/local/opt/openssl/lib" pip3 install psycopg2
