 ### Considerations

-1. notifications are sent for current events and not for past events. If your use case
-   requires you not to miss any notifications then subscriptions are probably not the best
-   option.
-2. subscriptions require a full duplex connection. Geth offers such connections in the
-   form of WebSocket and IPC (enabled by default).
-3. subscriptions are coupled to a connection. If the connection is closed all
-   subscriptions that are created over this connection are removed.
-4. notifications are stored in an internal buffer and sent from this buffer to the client.
-   If the client is unable to keep up and the number of buffered notifications reaches a
-   limit (currently 10k) the connection is closed. Keep in mind that subscribing to some
-   events can cause a flood of notifications, e.g. listening for all logs/blocks when the
-   node starts to synchronize.

 ## Create subscription

-Subscriptions are created with a regular RPC call with `eth_subscribe` as method and the
-subscription name as first parameter. If successful it returns the subscription id.
