Indexing with Update CBOR data format

Solr supports CBOR format for indexing as well as querying. It supports most popular languages and platforms. It’s much faster and efficient compared to JSON.

Python example

Save the following as cbor_post.py

import json
import requests
import cbor2

# JSON data to send (list of dictionaries)
json_data = [
    {
        "id" : "1",
        "name_s": "John Doe",
        "age_i": 30,
        "city_s": "New York"
    },
    {
        "id": "2",
        "name_s": "Jane Smith",
        "age_i": 25,
        "city_s": "London"
    }
]
# If there is only a single doc you can use the following
# json_data =    {
#         "id" : "6",
#         "name_s": "John Doe",
#         "age_i": 30,
#         "city_s": "New York"
#     }


# Convert JSON data to CBOR
cbor_data = cbor2.dumps(json_data)

# Set the endpoint URL
# ensure that the collection 'coll1' is already created
url = "http://localhost:8983/solr/coll1/update/cbor?commit=true"

# Send a POST request with CBOR data
response = requests.post(url, data=cbor_data, headers={"Content-Type": "application/cbor"})

# Check the response status
if response.status_code == 200:
    print("POST request sent successfully!")
    print("Response Body:", response.text)
else:
    print("Unexpected response status:", response.status_code)

Running the program

Install Python
Ensure that the dependencies are installed
```
pip install requests cbor2
```
Run the program
```
python3 cbor_post.py
```

Check the output

POST request sent successfully!
Response Body: {
"responseHeader":{
"rf":1,
"status":0,
"QTime":70
}
}

Node.js example

Save the following program into a file called script.js

const cbor = require('cbor');
const axios = require('axios');

async function main() {
// JSON data to send (list of JSON objects)
const jsonData = [
{
"id" : "1",
"name_s": "John Doe",
"age_i": 30,
"city_s": "New York"
},
{
"id": "2",
"name_s": "Jane Smith",
"age_i": 25,
"city_s": "London"
},
];

  // Convert JSON data to CBOR
  const cborData = cbor.encode(jsonData);

  // Set the endpoint URL
  const url = "http://localhost:8983/solr/coll1/update/cbor?commit=true"

  try {
    // Send a POST request with CBOR data
    const response = await axios.post(url, cborData, {
      headers: {
        'Content-Type': 'application/cbor',
      },
    });

    // Process the response
    console.log('POST request sent successfully!');
    console.log('Response:', response.data);
  } catch (error) {
    console.error('Error sending POST request:', error.message);
  }
}

main();

Running the program

Install Node.js
Ensure that the dependencies are installed
```
npm install cbor axios
```
Execute the script
```
node script.js
```

Check the output

POST request sent successfully!
Response: { responseHeader: { rf: 1, status: 0, QTime: 187 } }
