• Streaming CryptoCurrency data in real time

• CryptoCurrency Data fetching is done at intervals of 10 seconds from CoinRanking API through a golang application that extracts prices, exhchanges, dips and rises.

• The data is converted to a kafka encoded byte message with the name of the cryptocurrency as the key and the message as the value. The byte encoding is done adhering to the protobuffer schema and the message then goes through an additonal schema verification.

• Golang based Consumer application that reads from the offset of the kafka Cluster and converts the byte slice back to the original message.

• Each individual message consists of the cryptocurrency ID, name of the currency and the last price including the timestamp.

• The messages are then processed to get the linear, geomtric and harmonic aggregates. The aggregate calculation is done using rolling window functions with window size of 1 day.

• MongoDB time series collections are used as a sink to persist the aggregates as well as the real time prices.

• NodeJs-Express Backend to serve real time prices and aggregates through REST endpoints with support for gRPC endpoints as well.

• React App built using ANT Designs and React Charts to display data systematically and meaningfully.
