The present embodiment is for the diversity of the carrier of international logistics, and there is different pricing rules in different company, and the dispensing country that different company supports is inconsistent.Analyze these general character according to these differences, take out a set of general computation rule, provide external logistics freight charges to calculate; In the performance calculated, the use localization buffer memory of height, improve execution efficiency, because employ localized buffer memory, so many clusters of machines and basic data variation time, the configuration information of different machines buffer memory may be inconsistent, causes calculation of price result inconsistent, our solution is that the key of buffer memory is accomplished to unify configuration modification, addresses this problem.
Independently apply special messenger's maintenance optimization, reducing maintenance cost provides execution efficiency.
As shown in Fig. 1-Fig. 2, figure lower part provides service in the mode at serviceization interface, the model that freight charges calculate, and we add two app that freight charges template app/ standard freight charges calculate app, provide the freight charges of commodity to calculate to merchandise system.
The key-value mode redis buffer memory of in-process buffer memory ehcache and the nosql mentioned in the present embodiment, specifically refer to that the buffer memory of a) Ehcache uses, freight charges are calculated relevant quotation valency card information to be synchronized in ehcache, and our unified configuration center of the key of buffer memory is managed for configuration (if when needing corrigendum quotation valency card, by unified configuration center, key can be revised); Valency card information exists in the ehcache of storer, and when direct effect is exactly accounting price, no longer reading database, has all calculated in internal memory, and the calculating of let us is enough efficient.
B) the redis buffer memory of key-value, carries out precomputation in advance the product data once that our platform product needs exactly, exists in reids.Some conventional data of all online products of full platform, as: logistics cycle etc. series data of freight free, freight charges is once initialised in buffer memory; The new platform product uploading, revise afterwards, then system is progressively synchronized to the increment of the mode maintenance items of message queue, finally these data maintenances of all products in redis.Data in these redis, it is the result data that frequent program computation is good, such called side can directly directly read inside redis, in application to the high search index of batch performance requirement, efficiency improves can clearly, during without redis buffer memory, by the mode of far call, system interface calculates and on average wants about 20 milliseconds, and batch concurrent invocation concurrency also can only be the Thread Count within 300, and the ability to bear at interface is limited, occur soon abnormal (refusal connection etc. are abnormal), if the result calculated is stored in redis, directly fetch data from redis, concurrency that can be thousands of, as long as and just can data return in 9 milliseconds, ensure that the available of system is with stable.
Java Cache Framework EhCache EhCache is the in-process Cache Framework of a pure Java, has the features such as quick, keen-witted and capable, is the CacheProvider given tacit consent in Hibernate.
Main characteristic has:
1. quick
2. simple
3. many kinds of cache policies
4. data cached have two-stage: internal memory and disk, therefore without the need to worrying capacity problem
5. in the process that data cached meeting is restarted at virtual machine, write disk
6. can by RMI, the modes such as API can be inserted carry out distributed caching
7. there is the handover interface of buffer memory and cache manager
8. support many cache managers example, and multiple buffer zones of an example
9. providing the buffer memory of Hibernate to realize redis is a key-value storage system.Similar with Memcached, it supports that the value type stored is relatively more, comprises string (character string), list (chained list), set (set) and zset (ordered set).These data types are all supported push/pop, add/remove and are got common factor union and difference set and abundanter operation, and these operations are all atomicities.On this basis, redis supports the sequence of various different modes.The same with memcached, in order to guaranteed efficiency, data are all be buffered in internal memory.What distinguish is that redis periodically the data write disk upgraded or the log file that retouching operation write is added, and can achieve master-slave (principal and subordinate) synchronously on this basis.How Redis is a high performance key-value memory database to 2 performances.Official's the performance test results: set operates 110000 times per second, 81000 times per second of get operation.3 can deposit object and Memcached is similar, and its supports that the value type stored is relatively more, comprises string (character string), list (chained list), set (set) and zset (ordered set).These data types are all supported push/pop, add/remove and are got common factor union and difference set and abundanter operation.The maximum difference Replication(of 4 Redis and memcache is tree-like) data types(String, Lists, Sorted Sets, Hashes) a lot of developer thinks that Redis can not be faster than Memcached to persistence (snapshot, aof), Memcached is completely based on internal memory, and Redis has persistence preservation characteristics, even asynchronous, Redis also can not be faster than Memcached.But test result is Redis substantially to have comparative advantage.Thinking deeply this reason, the reason expected at present has this several respects always.Libevent。Different with Memcached, Redis does not select libevent.Many performances that Libevent causes code huge (current Redis code is less than 1/3 of libevent) to cater to versatility and sacrifices at particular platform.In Redis libevent, two file modifications achieve the epoll event loop (4) of oneself.The many developers of industry also advise Redis
Use another one libevent high-performance to substitute libev, but author still adhere to that Redis should be small and exquisite and go the thinking that relies on.An impressive details does not need to perform ./configure before being compiling Redis.CAS problem.CAS is that in Memcached, a kind of preventing competes the method revising resource eaily.CAS realizes needing for each cache key arranges a hiding cas token, the suitable value version number of cas, each set can need to increase progressively by token, therefore the dual expense of CPU and internal memory is brought, although these expenses are very little, serve trickle performance difference (5) will to both sides' opposite band to these expenses after unit 10G+ cache and QPS is up to ten thousand.The store data of 5 separate unit Redis must be less than physical memory
The data of Redis are all placed on internal memory and bring performance at a high speed, but also unreasonable part served by band.Such as a medium site has 1,000,000 registered users, if these data Redis store, the capacity of internal memory must can hold this 100 general-purpose family.But business actual conditions are 100 general-purpose families only has 50,000 any active ues, within 1 week, visited 1 time also only have 15 general-purpose families, therefore the data at whole 100 general-purpose families have unreasonable part in being all placed on, and RAM needs for cold data are checked.This is closely similar with operating system, and the data of all application access of operating system are all at internal memory, but if physical memory does not hold new data, the exchanges data that part is not accessed by operating system meeting intelligence for a long time, to disk, is new application slot milling.To application, what provide is not physical memory to modern operating system, but the concept of virtual memory (Virtual Memory).Based on identical consideration, Redis 2.0 too increases VM characteristic.Redis data capacity is allowed to breach the restriction of physical memory.And achieve the cold and hot separation of data.
The VM of 6 Redis realizes being that the VM repeating to make wheel Redis remains oneself according to epoll realization approach before and realizes.But mentioning OS in the introduction of previous action system also can help program to realize cold and hot data separating automatically, Redis only needs OS to apply for one piece of large internal memory, dsc data can be put into physical memory by OS automatically, cold exchanges data is to hard disk, the Varnish of " understanding of modern operating system " that another one is well-known realizes like this, also achieves extremely successful effect.Author antirez be interpreted as what want oneself realize in VM, mentioning several reason (6).The VM swapping in and out of main OS is based on Page concept, such as OS VM1 Page is 4K, as long as even if also have an element to only have 1 byte accessed in 4K, this page also can not by SWAP, change to reason too, read a byte and may change to the useless internal memory of 4K.Redis oneself realizes then can reaching the granularity controlling to change to.Block process during accessing operation system SWAP region of memory in addition is also cause Redis to want oneself to realize one of VM reason.
