海外TECH	DEV Community	A list of cache providers	https://dev.to/nfrankel/a-list-of-cache-providers-3o5o	A list of cache providersLast week we described several criteria to look at to choose a cache This week it s time to list Java cache providers based on these criteria Java Caching SystemGuavaCaffeineEhcacheInfinispanCoherence Community EditionIgniteGeodeHazelcastJava Caching SystemJCS is a distributed caching system written in Java It is intended to speed up applications by providing a means to manage cached data of various dynamic natures Like any caching system JCS is most useful for high read low put applications Latency times drop sharply and bottlenecks move away from the database in an effectively cached system ー Name Java Caching System Provider The Apache Foundation Source

Eviction strategies LRU Miscellaneous The JCS goes beyond simply caching objects in memory It provides numerous additional features Memory management Disk overflow and defragmentation Thread pool controls Element grouping Minimal dependencies Quick nested categorical removal Data expiration idle time and max life Extensible framework Fully configurable runtime parameters Region data separation and configuration Fine grained element configuration options Remote synchronization Remote store recovery Non blocking zombie balking facade pattern Lateral distribution of elements via HTTP TCP or UDP UDP Discovery of other caches Element event handling Remote server chaining or clustering and failover Custom event logging hooks Custom event queue injection Custom object serializer injection Key pattern matching retrieval Network efficient multi key retrievalGuava Guava is a set of core Java libraries from Google that includes new collection types such as multimap and multiset immutable

The get method accepts a Callable parameter that allows to get a value from the cache or compute it and store it if it s not found The API uses soft and weak references in keys and values Allows you

海外TECH	DEV Community	Destructuring in php?	https://dev.to/rrsai/destructuring-in-php-3ad1	Destructuring in php I work on javascript typescript on a constant basis and php on an infrequent basis on my legacy php app When I switch back to php after a long time of using javascript or typescript I really miss the clean code that you can write by using destructuring Now I talked a bit in another post about short circuit evaluation in js vs php and that terseness of syntax allows for writing code with much less boilerplate but what about destructuring in php Destructuring in jsFirst let s glance at destructuring in js const a b c rest a Apple b Banana c Cantalope d Durian not only is destructuring smooth it also allows for the powerful rest spread syntax I can t tell you the number of times that I have had some complex code block in javascript that was simplified by converting it to use destructuring or a possibly undefined property that destructuring handles smoothly like property api data user name may be undefined The dreaded chain of amp amp to avoid undefined propertiesif api amp amp api data amp amp api data user amp amp api data user name const username api data user name unknown finally do something another approach using the optional chaining operator from typescript const username api data user name Unknown user But here s another option using destructuring const data apiconst user dataconst name Unknown userconsole log name Unknown Destructuring in phpSadly php only supports a very limited bit of destructuring specifically when destructuring arrays by using list destructuring or destructuring a b c apple banana cantaloupe OR d e apple banana cantaloupe durian eggplant Thankfully you are also allowed to destructure named keys from associative arrays fruit a gt apple b gt banana c gt cantaloupe d gt durian e gt eggplant Have to set the fruit var because for some reason php doesn t like it when you try to directly destructure from the associative array you just created d gt d e gt e fruit echo d Durian nowecho e EggplantSo as long as you are dealing with an array or an associative array you can do some destructuring Destructuring php objectsIt s somewhat possible to destructure a php object by transforming it into an array api data user name George Washington A nested data objectTo destructure this you generally have to turn it into an array first and deal with the proposition of turning it s nested properties into arrays as well This may be a diminishing return on effort What about spreading values More modern versions of php at least support spread splat operators on arrays in weird ways having supported spread operators on function arguments since way back in php Spread on arrays in php fruit apple banana canteloupe durian a rest fruit var dump rest banana canteloupe durian For whatever reason the above doesn t quite work php errors out saying PHP Fatal error Spread operator is not supported in assignments in php shell code on line So the spread operator exists but it doesn t work quite the way I would expect in php The takeawayStill there is a lot of potential for destructuring as a way to clean up and simplify code	2021-10-31 17:14:36
