How to Read Output of MySQL EXPLAIN |
https://dev.to/amitiwary999/get-useful-information-from-mysql-explain-2i97
|
How to Read Output of MySQL EXPLAINMySQL is one of the most used RDMS We write different types of queries in MySQL Some used to be simple and some quries used to be complex that includes even more than tables When we write complex queries understanding the effect of the query is essential Sometimes poor written complex queries can be the reason for a database s poor performance We can use EXPLAIN to find the keys used in the query and how we can optimize them This blog is about how we can get useful information from the result of EXPLAIN The output of explain contains information on each table used in the query and in the order in which MySQL read the tables while processing the query It means that MySQL reads the data from the table present in the first row then finds the matching row in the table present in the second row and so on Columns present the EXPLAIN output are id select type table partitions possible keys key key len ref rows filtered type and extra select type There are different types of select This column shows the types of select The various types of selects are SIMPLE UNION SUBQUERY and DERIVED SIMPLE Select is simple It means no sub query or union is used here Subquery Any select query used in another select query but not in the FROM clause For example SELECT FROM student detail where address key in SELECT id from address where state Karnataka DERIVED SELECT query used in the FROM clause of another SELECT query is a DERIVED select type For example SELECT id FROM SELECT FROM address ad UNION Second SELECT query in UNION or subsequent SELECT query type is a UNION select type For example SELECT state FROM address where id UNION SELECT state from address where id UNION SELECT state from address where id table Name of the table It can be the table name or the name provided by us during a query or derived table in the row with id vale n partitioned Partition of the table from which the data is fetched If the table is not partitioned then it shows a NULL value or it may be possible that this column is not present in the output result if none of the tables is partitioned possible keys It shows all the possible indexes from which MySQL can use the index to find the rows in the table But this key is not dependent on the order of the table in the output result i e it does not depend on the order of the table in which MySQL process the query So it may be possible that none of the keys is used I have explained it below key It shows the actual key that is used to find the rows in the table Normally this key used to be one of the keys present in possible keys but it can be a different key too For example If it is optimized to fetch all the required columns from an index directly using the index scan then MySQL can use the index scan instead of the data row scan key len It shows the length of the key used to get the data If the key is a multi part key then key len helps us to find how many parts of the multi part key is used to get the data ref It indicates which column is used against the column present in the key to fetch the data from the table It can be const too i e a const value is used to compare For example SELECT FROM student detail sd INNER JOIN address ad ON sd address key ad id WHERE sd id In this query the key used in the JOIN clause is also present in the where clause and it means that we are fetching a fixed number of rows using that key from the table rows It indicated the approx not actual number of rows need to examine filtered The filtered column indicates an estimated percentage of table rows filtered by the table condition The maximum value is which means no filtering of rows occurred Values decreasing from indicate increasing amounts of filtering rows show the estimated number of rows examined and rows ×filtered shows the number of rows joined with the following table For example if the row is and the filtered is the number of rows to be joined with the following table is × You can check the official document the MySQL I will explain type and extra column usage in the next blog Both required detailed explanation and one blog is not enough for this |

Top ten popular static site generators (SSG) in 2023 |
https://dev.to/ezinne_anne/top-ten-popular-static-site-generators-ssg-in-2023-11p1
|
Top ten popular static site generators SSG in Static sites were previously composed of hard coded files comprising HTML templates and maintaining them was a grievous task So static site generators came along to remove those challenges making it easier to generate and run static sites while maintaining them While there are many static site generators on the market there are some exceptional ones I compiled the top ten popular static site generators to analyze their features and benefits But first you need to know the use cases of static site generators There are times when a dynamic site is required and vice versa Uses of static site generatorsStatic site generators are required when creating simple sites Sites that do not require any communication with the backend Sites that require user registration product reviews and so on do not need to be static But websites like portfolios documentation and even landing pages should be static sites Benefits of using static site generatorsHere are some benefits of using static site generators SpeedStatic sites are fast at rendering pages This is because they do not rely on servers to process their content All static sites do is render content and they are usually pre generated SecurityStatic sites do not use servers This makes them safer than CMs Although all sites on the internet always have the possibility of experiencing cyber attacks Static sites are safer because there is no server This makes it more difficult for attackers to find possible loopholes to launch an attack Reliability and performanceStatic sites can usually handle traffic and render content to users They are reliable too because they have little dependencies When you wish to access a static site the chances of seeing the content are high compared to dynamic sites Their mode of operation is simple and has a lower performance overhead Cost effectivenessBecause of the low cost of hosting static sites are inexpensive to use Normally using dynamic sites would require paying a specific amount of money to cover performance costs But with SSGs hosting platforms allow free hosting e g GitHub pages and Amazon S Flexibility and customizationStatic sites come with a set of pre built templates You could customize these templates and the user interface to suit your taste A network of distributed servers serves content this makes the site flexible enough to be rendered on any platform ーweb mobile or desktop ーand in any geographic location too Top ten static site generatorsThe top ten popular static site generators are JekyllEleventyHugoGatsbyNext jsPelicanHexoNuxt jsGridsomeMetalsmith Jekyll ーthe most popular SSGJekyll is a static site generator built by Tom Preston Werner in GitHub uses it to make static sites and host them on GitHub pages It offers multiple themes using its Liquid template language With Jekyll you can present the necessary metadata for your page for SEO and other benefits Also Jekyll supports Markdown and it compiles your Markdown into a blog form Jekyll and GitHub pages are both GitHub products so they are usually compatible with each other You could combine it with other hosting platforms and it supports third party plugins Jekyll is written in Ruby You would need to install Ruby and other programs to use it AdvantagesIt is blog friendly It is free to use DisadvantagesIt requires Ruby to be installed Eleventy ーthe simplest static site generatorEleventy is a static site generator for JavaScript users They created it with vanilla JavaScript and Nodejs The Liquid

free It supports a wide range of hosting platforms like Netlify GitHub pages and so on AdvantagesIt is easy to set up and use It has well detailed documentation support DisadvantagesIt requires technical knowledge to use Gatsby ーbest for building progressive web appsGatsby is the best static site generator for building progressive web apps because it provides the features needed to build them This SSG was built with React and it is loved by React developers and the Jamstack community Gatsby is used primarily by technical users It uses GraphQL to import data You can easily bring in content from content management systems apps and other platforms and Gatsby turns it around to generate content for you AdvantagesYou can use multiple plugins with it When constructing a site it follows accessibility guidelines DisadvantagesIt requires technical knowledge to access it Nextjs ーbest app SSGNextjs is a powerful React js framework for building static applications Nextjs does static site generation but there are more It also supports server side rendering image optimization typescript configuration and so on It is written for developers and is one of the best static site generators for building apps AdvantagesIt provides features like CSS support automatic routing and so on It has great documentation and a developer community DisadvantagesIt is not for non technical

AdvantagesIt is flexible because of the various templates and themes it supports Rapid development and deploymentDisadvantagesIt requires technical knowledge Nuxtjs ーthe best for Vue developersNuxtjs is a Vue js framework that is modelled after Nextjs Like Nextjs it supports server side rendering typescript configuration automatic routing and so on Nuxtjs is used as an SSG when creating Vuejs applications AdvantagesIt offers significant features to get your site up and running It is a great tool for Vue js developers DisadvantagesIt is for Vuejs developers only Gridsome ーJamstack SSG tool for Vue developersGridsome is an SSG tool that uses Vuejs to build templates It is like Gatsby in that it creates progressive web apps too and they have a similar design Gridsome uses GraphQL too like Gatsby and supports the use of markdown renders content quickly and provides CMS integrations It is open source and free to use AdvantagesIt is free and has community support It builds large sites faster DisadvantagesIt has a small community and sometimes it is better to get help from the Jamstack community instead Metalsmith ーthe best customizable SSGMetalsmith is an open source SSG that is easily customizable It is also free to use Metalsmith has plugins available that carry out the static site generation process These plugins use a somewhat distributed approach to make it possible for users to customise the tool to their taste You could also use Metalsmith to generate PDF ePUB and other digital content AdvantagesIt can convert various formats It is flexible DisadvantagesIt does not have strong community support ConclusionThat sums up the top ten popular SSGs These tools are great to use and these reviews are based on their popularity There are other new SSGs that may be less popular but have outstanding features If you know of any please share them in the comments Thanks Further ReadingIf you enjoyed reading this you ll probably enjoy similar reads Top ten headless CMS in
