Compression
If you want to compress messages before producing them to Memphis.dev, you can manually compress the messages using a compression library like zlib or gzip and then send the compressed data to Memphis.dev. Here's a step-by-step guide on how to do this:
You'll need the
memphis library for producing messages to Memphis and a compression library like zlib or gzip for message compression. You can install these libraries using pip:1
from memphis import Memphis, Headers
2
from memphis.types import Retention, Storage
3
import asyncio
4
import zlib
Create the message that you want to send to Memphis. For example:
1
message = "This is the message you want to send to Kafka."
Use the compression library to compress the message data:
1
compressed_message = zlib.compress(message.encode('utf-8')) # Use zlib for compression
2
# or
3
# compressed_message = gzip.compress(message.encode('utf-8')) # Use gzip for compression
1
await producer.produce(bytearray(compressed_message)) # you can send the message parameter as dict as well
1
from memphis import Memphis, Headers
2
from memphis.types import Retention, Storage
3
import asyncio
4
import zlib
5
6
async def main():
7
try:
8
memphis = Memphis()
9
await memphis.connect(host="localhost", username="root", password="memphis")
10
message = "This is the message you want to send to Kafka."
11
compressed_message = zlib.compress(message.encode('utf-8')) # Use zlib for compression
12
producer = await memphis.producer(station_name="memphis-test", producer_name="producer-test")
13
await producer.produce(bytearray(compressed_message)) # you can send the message parameter as dict as well
14
15
except Exception as e:
16
print(e)
17
18
finally:
19
await memphis.close()
20
21
if __name__ == '__main__':
22
asyncio.run(main())
This code demonstrates how to manually compress messages using zlib or gzip before sending them to Memphis. When consuming messages, you would need to decompress the messages using the same compression library you used for compression before processing the data.
