How to deal with growing execution stream data? Is there a reset function?

[flolege]

I am getting my execution data by subscribing to the execution table:

    bitmexWebsocket.addStream('XBTUSD', 'execution', async function (data, symbol, tableName) {
        if (!data.length) {return}      
        ...
   
    })

For me it seems the data object is an accumulation of all execution events which happened since subscription.

If one gets frequent executions, the data object can get huge, right?

So is there a kind of reset functionality or what are the best practices to deal with this issue? Un- and resubscribe? How?
