Ethereum: Binance Multithread Sockets – functions are not called concurrently

Ethereum: Binance Multithreaded Sockets – Functions Not Called Concurrently

Binance multithreaded sockets provide the ability to receive real-time market data from the Binance API in parallel, providing efficient and concurrent access to the data. However, if not managed properly, this can cause problems.

Concurrency Considerations

When using multithreaded sockets, it is important to ensure that all threads are properly synchronized to prevent deadlocks and other concurrency-related issues. One common problem is when multiple threads attempt to call functions at the same time without proper synchronization, resulting in unexpected behavior or errors.

There are a few potential problems with the code snippet provided:

• Asyncio.gather()

  call: The “asyncio.gather()” function is used to wait for all tasks to complete and then return them as an iterator. While this can be useful in certain scenarios, it may not be the most efficient way to manage concurrency in this case.

• Calling Analyze(res) within a loop. Calling Analyze(res) within a loop can result in multiple threads calling the same function at the same time, which can lead to unexpected behavior and errors.

Recommended Workaround

To address these issues, we recommend a more robust approach that leverages the async/await syntax and synchronization mechanisms provided by the Binance API.

import asyncio
async def analyze(res):





Analyze the received data
return, await process_analysis(res)
async def main ():
client = AsyncClient(binance_url="
tasks = []
for symbol, pair symbol_pair:
task = asyncio.create_task(analyze(res=pair))
tasks.append(task)
results = await asyncio.gather(*tasks)

Process the results
process_results(results)
async def main ():

Define the symbol pairs to analyze
symbol_pair = [("AAPL", "USD"), ("BTCUSDT", "Btcusdt")]

Analyze and process each pair
await asyncio.gather(*[analyze(res=pair) pair symbol_pair])

Run the main function
asyncio.run(main())

Explanation

In this revised code snippet:

• We define a function “analyze” that performs some analysis on the received data using “process_analysis”.

• In the “main” function, we create a list of tasks to perform the analysis concurrently using “asyncio.gather”. Each task calls the “analyze” function with the corresponding symbol and pair.

• We use “asyncio.create_task” to create a new task for each iteration of the loop. This allows us to properly manage concurrency.

• Finally, we process the results by calling “process_results”, which is not shown in this snippet, but is usually used to perform some operation on the received data.

By following these guidelines and using the async/await syntax, we can ensure that our code is properly synchronized and runs concurrently, reducing the risk of problems and errors.
