Time series data 

 

• Time-series databases are one of the database categories with the fastest growth right now. Many developers today attempt to understand managing time-series data at the database layer.
• As a result, the cloud ushers in ever more “self-service,” the volume of data keeps growing as innovation delivers more computing power and storage capacity, and the data itself continues to grow.
• The most intriguing deep analytics and real-time data feature developers are attempting to include into their apps use time-series data, which is also difficult to recognise and and may be highly expensive to get wrong.

Now, let’s examine what time-series data is, what distinguishes these workloads from one another, and what specifications developers must be aware of to succeed.

 

Time-stamped data is present in everything and everywhere

 

Time-series data is everywhere; it permeates every aspect of business and is all around us. Almost everyone, from Wall Street to the average person, utilises or produces time-series data throughout the day.

Time-series data is being produced and recorded, whether you’re turning off your lights or using your car to commute to work, taking the train, listening to Spotify, or riding the subway. So what precisely is time-series data, and how can it help us integrate the physical and digital worlds to increase efficiency, productivity, safety, health, and so many more applications that enhance every part of our lives?

 

How can we describe the time series data?

 

We can describe “time-series data” as a sequence of metrics gathered over time for one specific object. “Time-series data” is frequently simply referred to as data with a time-stamp.

Simple enough, but isn’t it pretty much all the information you need?

You may be fundamentally correct, but a time-series workload’s needs are distinct from those of raw time-series data points.

Let’s examine one in more detail.

You might wish to keep track of an index’s closing price, such as the NASDAQ, over time in finance. A condensed version of this dataset would resemble this:

Time	NASDAQ closing price
2022-08-01 16:00:00:00	12637.50
2022-08-02 16:00:00:00	13321.98
2022-08-03 16:00:00:00	11981.55
2022-08-04 16:00:00:00	12036.25

 

• This is an illustration of time-series data; it is one-dimensional, the data points are specific to the NASDAQ, and they were gathered over time. The primary dimension that distinguishes the series is time. However, it’s doubtful that you are merely gathering information for a single entity; instead, it’s more probable that developers will be utilising information spanning several entities and dimensions.
• This is known as “panel data,” also known as “cross-sectional time-series data.” Since it is essentially just made up of numerous time series, multi-dimensional time-series data is the best way to describe it.
• Consider a recent use case in which we want to gather information about each security listed on the NASDAQ throughout the day to create a tool that enables users to monitor and chart price changes and trading volume in real-time.

Time	Security Symbol	Trade Price	Volume
2022-08-01 11:05:00:000	MSFT	312.50	5
2022-08-01 11:05:01:000	MSFT	312:49	1
2022-08-01 11:05:01:000	AMZN	107.56	10
2022-08-01 11:06:00:000	IBM	37.53	1000
2022-08-01 11:06:01:000	AMZN	106.53	1

 

• The dataset has grown significantly in size, scope, and user power. The combination of time and security symbols, which together make up two separate dimensions, uniquely identifies a series.

 

WHAT TO KNOW?

 

• We cannot fully comprehend time-series data demands by simply defining terms like “time-series data” and “panel data.” Understanding “cardinality,” defined as the quantity of distinct series, is another crucial topic.
• A series is uniquely recognised by “time” if it is one-dimensional time-series data or by “time” and other dimensions or metadata, such as a security symbol, if it is more often “panel data,” as was mentioned above.

 

TRUE FACTS OF TIME SERIES DATABASES 

 

Why are time-series databases still gaining enormous popularity while they have been available for a while?

 

• Everything ultimately comes down to our thirst for knowledge and information, which can only be stoked by gathering and analysing more data.
• We can study time-series data more thoroughly and derive insights from how data evolves as we amass more.
• Time-series data is gathered with low-level granularity, is frequently high-volume due to its continuous nature, and will continue to expand rapidly in size as more data points are gathered.

 

To gain in-depth knowledge on time series databases, it is essential to know the basic programming. If you are struggling with the Haskell programming assignment, you can take online help examples to overcome the challenges.

 

Multiple possibilities: The low-level granularity of time-series data adds to its complexity for developers but offers a wide range of possibilities for its use and end-state. Therefore, time-series data is best collected to provide as much detail as possible when answering queries about our data.

 

For instance,

 

• An F1 car’s sensors gather dozens of parameters to track and assess the car’s performance during and after race laps.
• Sensors on a rocket, however, capture metrics like temperature every nanosecond.
• The principal value of time-series data comes from forecasting and predicting future outcomes, which is possible as developers gather more data points with rich detail.
• This allows them to infer more insightful conclusions from the changes taking place.
• The attention, usability, and technological advancement required to manage and process all of this large volume effectively, low-level granularity time-series data have been brought by time-series databases.

 

Some traditional time-series examples 

 

• Sensor data – Your heart rate, sleep habits, number of steps taken, and other metrics may be recorded by a smartwatch or any general sensor data produced by IoT devices. These measurements would be part of your dataset, containing additional metadata like customer or sensor identifiers and be continually generated throughout time, identified by time.
• Financial tick data – As previously mentioned, streaming trade data is available all day long for every security listed on the NASDAQ and may include the stock name or identification, price, trade volume, etc.
• Fleet monitoring: Information is gathered via a sensor on a car and may include the car’s identification number, the time, and metrics like the car’s current speed, GPS location, fuel level, etc.

 

Is a time series database necessary?

 

Suppose the goal of gathering more and more time-series data is more than just a byproduct of technological advancement. In that case, we need systems designed for the special performance considerations of time-series data workloads in order to continue learning, derive valuable insights, and forecast future outcomes on this low-level granularity time-series data.

When selecting a database, developers often analyse and strive to optimise for the following primary performance considerations, just like they would with most other data types or workloads:

• Read
• Write
• Scalability (cardinality handling)
• Efficiency of storage

 

Collection of data: Most databases ultimately store their data on discs, and discs typically store data in blocks of 4, 8, and 32 kilobytes.

Storing time-series data: When the app developers attempt to store time-series data in a conventional system designed for OLTP, each received record is sequentially saved on a disc block. We require a few indexes to locate them. Each data point has an index, which enables them to locate it, remove it, and, if required, employ replication.

 

What are the consequences?

The issue worsens when you try to get this data back because the underlying hardware requires you to do it block by block. It follows that reading requires much more effort than it does.

 

Solutions 

• By focusing on the distinct properties of time-series data workloads and, ultimately, their consumption patterns, time-series databases aim to address this issue. Time is a first-class citizen. Hence data should always be sorted by time.
• This has special advantages for reading performance on recent data because systems can typically keep data cached in memory.
• Examining what problems systems are trying to solve concerning the time-series workload characteristics mentioned above is one of the most straightforward approaches to determining which solution to use.

 

To conclude,

Time series data can be interesting to the app developers if they go beyond their textbooks and explore more practical things. Everything is made up of essential building blocks called data. Time-series data allows app developers to develop more prosperous, in-depth knowledge and information, which ultimately distinguishes it from raw data by giving it greater breadth and depth.
