Zero temporary files: In-memory document streaming with WFile.

Writing temporary files to disk just to send an export report is an anti-pattern. wconnect's WFile abstraction lets you stream binary documents straight from RAM to Telegram chats.

Here is how you implement In-Memory WFile Abstraction in production with wconnect:

from wconnect import WFile, Wtelegram

# Generate dynamic CSV report in memory
csv_bytes = b"transaction_id,amount,status\nTX_9812,450.00,SETTLED\nTX_9813,120.50,SETTLED"
report_file = WFile(content=csv_bytes, name="settlement_report.csv")

with Wtelegram() as producer:
    producer.send_document(
        to="6586101740",
        file=report_file,
        caption="📊 End-of-day transaction settlement"
    )

Why This Matters:

• Zero boilerplate decorators (@bot.on_command, @bot.on_message, @bot.consumer).
• Stream binary files directly from RAM using WFile.
• Non-blocking daemon poller with run_consumers(block=False).

When designing high-throughput analytical ingestion pipelines for ClickHouse, balancing memory pressure against CPU serialization is critical. Lazy chunking and vectorization prevent memory spikes while keeping client network throughput saturated.

What chunk sizing and compression thresholds have you found most optimal in production OLAP workloads?
