Streaming Database is the update to traditional Database

Streaming database helps keep records of events, generating statistical profiles of blocks of time and reports from queries.


The trends related to technologies continuously evolve at a frenetic speed. Current trends include IoT(internet of things) nearly in every field of life; with increasing data rates over the internet, engineers and data experts are working on projects to accumulate data and use it to control industrial plants and homes.

The aim:

Programmers and Db experts are investing time to achieve their goal for the development and enhancement of pipelines for streaming databases, so they can analyze, accept and store the precious and valuable data. This development can help to handle unceasing flow and queries from tools that want to make or append decisions based upon data.

How it works:

Key job of a streaming database is to enable queries and track a series of events to make decisions or to produce profiles of blocks of time; thus, a streaming DB is no different from the time series Db and log database. A streaming database responds to the data and produces reports from it. In addition to this, it can fill up the dashboards to track what’s occurring to aid the users in making clever decisions. Tools used for streaming databases act as a pipeline that controls and absorbs information from the incoming flow of data and stocks it up in a database.

How it works:

There are different beliefs regarding streaming databases; some think it is an entire system, while some treat it as a module created by adding pipelines to a traditional database.

Some examples of its use cases are 

  • Time-critical service (Uber)
  • Irregularities or inconsistency searching software(video analyzing tools).
  • Analyzation software(scientific or geographic measurements)

The streaming database contains the data that is divided into 2 parts or tiers. The raw inputs are a historical record of unchangeable data but can only be appended over time.

The other layers hold the summaries for the data streams collected over time, e.g. finding/comparing the time or days for an event’s occurrence. Such data is stored in Tables which makes it similar to traditional databases.

Data size can be reduced by the use of streaming database overcome storage shortage issues e.g. it saves an average value instead of storing all of the unnecessary calculations.

The streaming database allows the developers to change the behavior of the latest data and how it can be integrated. This leads the developer to keep important data in the tables and dispose of the unneeded ones. The developers can change behaviors and integration in a streaming database so, this leads the developer to keep important data in the tables and dispose of the unneeded ones

Streaming Database

How it’s evolving: 

New firms and companies are overcoming the issues and challenges by building integrated tools or creating a layer for stream handling with an existing database. For example, Appache’s Kafka is an example of integrating a system with a current database. Kafka is an open-source message handler system; it most often interlinks different software.

In the same way, Amazon offers a system called Kinesis. This system’s specialty is that it provides pathways for working with videos. Furthermore, usage of Ai tools integration to recognize video analysis and sage-maker for ML(machine learning). However, more companies are building open source projects e.g. Debezium, which aids to transform data from event streams, most probably by KAFKA

Evolving of Database

Yes, but:

There are some constraints related to streaming databases e.g it doesn’t offer as many of the functions and APIs like that of the traditional databases cause the main task for the streaming database is to manage the flow of aggregate data. It may be unable to supply complex views or to define joins (for the incoming data).
