Szczytowy wzrost cen serwerów napędzany popytem na AI, względem notowań z 2025 roku
Gartner03/2026global
An HTTP mechanism where the server maintains a connection and unidirectionally sends updates to the client. Useful for tracking long-running task progress, notifications, and streaming responses.
Why it matters
Enables the server to send updates without client polling: progress of long tasks or AI response streams flow to the browser via a single persistent connection.
What's missing without it
Without this mechanism, the client polls the server in a loop — hundreds of unnecessary requests, delays, and overhead that no one needs.
When it is used
Used for showing task progress, notifications, and streaming AI model responses; simpler than WebSocket when data flows in one direction.
How we use it
The dashboard shows transcription or audio generation progress live without refreshing the page.
