In this chapter, we learned how to deal with massive amounts of data. We called this the problem of backpressure. We can use two different approaches to deal with backpressure: lossy strategies and loss-less strategies.
We also learned about the advantages and disadvantages of each approach, and also which operators we can use to mitigate them.
At the end of the chapter, we also received more tools to query for data in our observables, such as the first() operator, some take() operators, and some skip() operators.
In the next chapter, we will learn about operators to combine different sources of data.
