AWS Step Functions Supports Variables and JSONata

AWS Step Functions Supports Variables and JSONata

Step Functions - Yes, that orchestrator or workflow service in AWS used to be used primarily to call lambda functions in various formats or orders, but in recent years, it has become more and more popular due to its support for nearly all of the key AWS SDK integrations.

🌟 In fact, some things, no no many things can be done only by using step functions without even having a lambda functions or needing to write python or node.js code.

😫 But while writing step functions as an developer, Obviously you and me, for sure come across this situation of writing extra, extra steps to do simple manipulation of data in input or result and pass through to other steps.

😀 Now you don't need to do that, anymore. Your step functions can get smaller, lighter and shorter with less pass through manipulation states.

😅 Without further hyping, let's see what is that feature released by AWS.

📢 Variables :-

✓ With this option, you can declare your input variable at the top of step function and access in each and every step, right upto the bottom, without needing to pass through every step.

✓ Since now your variable is at the top, you can re-arrange or modify any of the intermediate without burden.

📢 JSONata :-

✓ It's a simple, lightweight query and transformation language for JSON data.

✓ Using this you can do things like, simple time/data format change to complex mathematical calculation right inside your step functions state itself, without needing to call an lambda functions to do this.

💬 Previously while you are writing step functions you would used JSONpath based expression intrinsic functions, so your step functions might looked bigger🙆. Now with JSONata you should see step functions much smaller 🤏 as the extra step of transition are neglected.

🏌️‍♂️If you are already working with step functions, then you are going to like this 🤩.

Hope you learned something new 🎉.

BIG DATA ANALYTICS

BIG DATA ANALYTICS Have you ever hit upon how Amazon and Flip kart could possible verdict what we want; how the Google auto completes our search; how the YouTube looks into videos we want to watch? When we open YouTube, we will be at sixes and sevens, when we find ads related to what we have searched earlier in the past days. This is where we find ourselves in the era of big data analytics. More than 3 trillion bytes of information are being generated everyday through our smart phones, tablets, GPS devices, etc. Have we thought about what can be done with all these information? This is where the data analytics comes into play. Big data analytics is just the study of future build up to store data in order to extract the behaviour patterns. The entire social networking website gathers our data which are related to our interest which is usually done by using our past search or any other social information. Data analytics will lead to a walkover in near future....

Hidden things About Amazon SageMaker Studio

Did you know about Amazon SageMaker Studio❓ 🤔 Like you, I initially believed that this service was only for data-related tasks and that regular engineers/developers weren't supposed to use it. ✒️ However, after using it for a while, I would suggest that it can help you with more than just data related tasks. In fact, an organization can use SageMaker Studio to bring their entire SDLC 💪. 😬 Because of its data'ish ness like gimick we (normal non-data developers) always felt, "Oh, SageMaker, it's expensive 😱 so no, no don't go that side 🤐." 😷 As a result, we shrank and missed the hidden gem 💎 and its possibilities, as well as the opportunity to utilize such a fantastic and powerful tool 🔥. ✒️ Let me give you some glimpse with a preview of what SageMaker Studio is capable of. ✒️ SageMaker is big service, but in this post am limiting my context towards SageMaker Studio only. ✒️ And mostly, this write-up is for developers who enjoy writin...

Python #23-Regex findall() and sub() in Python

Previous Post : Python #22-Regex match() and search() in Python Next Post : Coming soon........ re.findall(): It find all sub strings where the RE matches, and return them as a list. This function is used to catch all the matching patterns in the strings. Note Worthy: re.match() + re.search() = re.findall() Syntax: re.findall(pattern, string) Source Code: import re variable = re.findall(r"Google", "Google Bird learn around Google and gives the best contents to the viewrs") print variable Output: ['Google', 'Google'] re.sub(): This is used to search a pattern in the string an replace with the new sub string. Syntax: re.sub(pattern, replac...
