becoming an essential skill in today s Programming and Software Development world and Kubernetes is an important concept and tool for both developers and DevOps engineers In today s cloud computing world Kubernetes also known as K is quickly becoming an essential tool for many of us and why not It takes container based deployment to another level and allows you to manage it on the scale You can use Kubernetes to scale your container based or Docker based environment or let Kubernetes do all the work for you by leveraging its auto scaling feature Many DevOps beginners think that Docker and Kubernetes are the same but they are not Docker provides a container to deploy your application and commands to interact with those but container but Kubernetes is actually a container management technology which decides how many containers are needed and deal with other management aspects In fact Kubernetes or Ks is arguably the most important container management technology in the world at this moment and you shouldn t be surprised that the roots of Kubernetes lie in Google itself It s not a Google tool but created by a couple of Google developers as an open source alternative of similar tools they have used in Google to manage containers at scale Kubernetes comes with some mind boggling features like auto scaling it s very reliable and also an extremely powerful container orchestration engine probably the best at this moment It allows you to convert your infrastructure into a Container as a Service Platform bringing in some of the awe inspiring features like Zero

海外TECH	DEV Community	Data Loading in Entity Framework	https://dev.to/grontis/data-loading-in-entity-framework-2foe	Data Loading in Entity FrameworkData retrieval is an important aspect of designing efficient applications in software development It is common for applications to require data from a database in order to function Data access is a critical performance factor that must be carefully considered in this regard The three common methods of loading data from a database are lazy eager and explicit loading In this article we will look at the differences between these methods as well as their benefits and drawbacks Lazy LoadingLazy loading is a technique that allows us to defer the loading of related objects until they are accessed In other words we only load the required data when we need it rather than loading everything at once Let s consider an example to understand lazy loading better Suppose we have two entities Author and Book and we want to retrieve all authors and their corresponding books With lazy loading we would first retrieve all authors from the database and then retrieve the books for each author only when needed This approach is beneficial because it reduces the number of queries sent to the database and avoids loading unnecessary data Implementation by Proxies package We are going to see how to implement lazy loading in EF Core The first method is by installing a Proxy Package provided by Microsoft All you have to do is install Microsoft EntityFrameworkCore Proxies package which will add all the required proxies needed to run Lazy Loading and enabling it with a call to UseLazyLoadingProxies This can be achieved either in OnConfiguring method of your Context class using Microsoft EntityFrameworkCore namespace DataLoading internal class MyContext DbContext protected override void OnConfiguring DbContextOptionsBuilder optionsBuilder optionsBuilder UseLazyLoadingProxies UseInMemoryDatabase databaseName MyDb or when using AddDbContext most likely in the Program cs builder Services AddDbContext lt MyContext gt b gt b UseLazyLoadingProxies UseInMemoryDatabase MyDb Any navigation property that can be overridden and is virtual and on a class that can be inherited from will then have lazy loading enabled by EF Core The Author Books and Book Author navigation properties for instance will be lazy loaded in the following entities public class Author public int Id get set public string Name get set public virtual ICollection lt Book gt Books get set public class Book public int Id get set public int AuthorId get set public string Name get set public decimal Price get set public virtual Author Author get set In the example above we use the virtual keyword to mark the Books property as virtual indicating that it should be lazily loaded When we retrieve authors from the database Entity Framework will generate SQL queries to retrieve only the authors and not the books When we access the Book property for a specific Author Entity Framework generates another SQL query to retrieve the corresponding books Implementation by ILazyLoader service The second method is by injecting the ILazyLoader service to an entity Lets look at an example public class Author private ICollection lt Book gt books public Author private Author ILazyLoader lazyLoader LazyLoader lazyLoader private ILazyLoader LazyLoader get set public int Id get set public string Name get set public virtual ICollection lt Book gt Books get gt LazyLoader Load this ref books set gt books value public class Book private Author author public Book private Book ILazyLoader lazyLoader LazyLoader lazyLoader private ILazyLoader LazyLoader get set public int Id get set public int AuthorId get set public string Name get set public decimal Price get set public virtual Author Author get gt LazyLoader Load this ref author set gt author value This technique enables entity instances generated with new to lazy load once they are attached to a context and does not require entity types to inherit from or navigation properties to be virtual Now when you query for an Author entity EF will generate an SQL query that looks like this SELECT Id Name FROM Authors WHERE Id idThis query only selects the Id and Name columns from the Authors table as EF knows that it doesn t need to load the Books collection yet Then when you access the Books property on the Author entity EF will generate another SQL query to load the related Book entities SELECT Id Name Price AuthorId FROM Books WHERE AuthorId authorIdSimilarly when you query for a Book entity EF will generate a SQL query that looks like this SELECT Id Name Price AuthorId FROM Books WHERE Id idThis query only selects the Id Name Price and AuthorId columns from the Books table as EF knows that it doesn t need to load the related Author entity yet Then when you access the Author property on the Book entity EF will generate another SQL query to load the related Author entity SELECT Id Name FROM Authors WHERE Id authorIdThis query selects the Id and Name columns from the Authors table which is all that s needed to populate the Author property on the Book entity Eager LoadingThe opposite of lazy loading is eager loading When we retrieve data from the database using eager loading we load the primary object as well as all the related objects When we are certain that we will want all the relevant data and wish to reduce the number of database queries this strategy is advantageous To further understand eager loading let s look at an example Let s say we have the same two entities Author and Book and we want to use eager loading to get a list of all authors and their books ImplementationHere is an example of how to implement eager loading using Entity Framework in C To load authors with eager loadingusing var context new MyContext var authors context Authors Include author gt author Books ToList foreach var author in authors Console WriteLine authors Name foreach var book in author Books Console WriteLine book Name The Include method is used in the example above to express the desire to eagerly load the Booksproperty for each Author The Authors and Books tables are joined together by Entity Framework to provide a single SQL query that returns all the necessary information SELECT a Id a Name b Id b Name b Price b AuthorId FROM Authors AS a LEFT JOIN Books AS b ON a Id b AuthorId WHERE a Id authorIdIt is worth mentioning that you can include multiple levels of related data using the ThenInclude method For example using var context new MyContext var authors context Authors Include author gt author Books ThenInclude book gt book CoverImage Include author gt author ContactDetails ToList Additionally we can configure to always include a navigation in a model by using the AutoInclude method on the modelBuilder modelBuilder Entity lt Author gt Navigation author gt author Books AutoInclude Use the IgnoreAutoIncludes method in your query if you don t want to load associated data through a navigation that is defined at the model level to be automatically included The user configured auto include navigations will all cease loading if this approach is used Using the query below will retrieve all authors from the database but Books won t load even if it is set to AutoInclude using var context new MyContext var authors context Authors IgnoreAutoIncludes ToList We have to be extra cautious when we use eager loading on collection navigation because it might cause serious performance issues Explicit LoadingAfter the main object has been loaded explicit loading allows you to load related entities as needed By limiting the amount of data that needs to be imported from the database it offers a mechanism to selectively load relevant entities only when they are required which can enhance efficiency In explicit loading you use the Load method on a CollectionEntry or ReferenceEntry object to explicitly load the related entities A CollectionEntry object represents a collection navigation property on an entity while a ReferenceEntry object represents a reference navigation property on an entity When you don t want to suffer the overhead of loading associated entities each time the primary entity is loaded explicit loading can be helpful For instance you can use explicit loading to load only the related entities you require at the moment if you have a lot of entities but only occasionally need to access related entities Lazy loading must be enabled for explicit loading to function because it depends on it Calling Load on a CollectionEntry or ReferenceEntry object has no effect if lazy loading is not enabled ImplementationLets see an example and the SQL query generated by EF Core var author dbContext Authors Find authorId dbContext Entry author Collection a gt a Books Load Assuming that lazy loading is enabled the initial query to retrieve the Author entity would look something like this SELECT a Id a Name FROM Authors AS a WHERE a Id authorIdWhen Load is called on the CollectionEntry object for the Books collection Entity Framework generates a separate query to retrieve the related Book entities SELECT b Id b Name b Price b AuthorId FROM Books AS b WHERE b AuthorId authorId ConclusionIn conclusion lazy loading automatically loads related entities when they are visited for the first time making it a practical and simple method If too many related entities are loaded at once however it may cause performance issues In contrast eager loading loads related entities in addition to the main entity in a single query which might be more effective than lazy loading in circumstances when you know you will require the associated entities in advance It can however lead to queries that are more complex and may take longer to perform In circumstances when you only need to access related entities for a subset of entities explicit loading is a selective technique that loads related entities as needed after the primary entity has been loaded On the other hand it could be less straightforward to use and takes more code to implement The optimal strategy ultimately depends on the particular needs of your application and the trade offs between simplicity performance and complexity	2023-02-28 08:34:53

functions methodsRegex FlagsRegular Expression Character Regular ExpressionsRegular Expressions Regex are used in text data to match patterns They are used to find specific patterns in strings or collections of strings They may also be used to search for find change and modify text data They can also be utilized to validate user input like email addresses and phone numbers We need to import the re module to use regex in python Regex SyntaxBefore we get into the syntax we must understand that regex is a language It has its own syntax and rules Regex is found in python and other programming languages like Java C JavaScript PHP etc So if you have used regex in any of these languages you will find that the syntax is the same Below are some of the most common syntax that makes up regex any character except newline start of string end of string or more occurrences of the preceding character or more occurrences of the preceding character or occurrences of the preceding character exactly occurrences of the preceding character to occurrences of the preceding character or more occurrences of the preceding character a z any lowercase letter A Z any uppercase letter any

start returns the start position of the match print search end returns the end position of the match print search group fox returns the part of the string where there was a match This is more useful when there s multiple searches print re search Fox string None returns None if no match was found The compile method returns a regex pattern object which can be used to match all occurrences of a
