Synchronizer (about 1 People weekly workload, the risk is very low), but dispersed the risk, the first step of the technical risk (Lookup/dal infrastructure transformation) and the second step of the business function risk (Oracle change MySQL syntax) separate. Two-stage on-line is a one-time success, especially the second stage on-line, more than 100 relying party application simple restart to complete the upgrade, there is no big problem in the middle.SummarizeHere, MySQL

Website construction often need to output a column of sub-columns, corresponding to the Sub-column list page also need to output the parent column of the Sub-column list, THINKCMF can output all sub-columns, but not in the

For example, return Json (models) is returned in Jsonresult, and the models structure is as follows:Models returns a sequence containing four collections, each of which contains a sequence of subcollections, "child".The question is, if we use jquery's $.post, how do we loop out the data in these two sets of sequences?Here's how:$.post ("/admin/getpermissionsforcurruser", function (data, status) {if (status = = "Success") {var gethtml = ""; $.each (data, function (i, items) {//The data her

List (list) and set (set) are most commonly used throughout the collection frameworkI. Features of list set setCollection Sub-interfaces:1, List: ordered (in the same order of deposit and withdrawal), the elements are indexed and can be repeatedThe API documentation explain

an index table to record the mapping relationship of Login_name->uid • When accessed using login_name, the index table is used to query the UID, then the corresponding Coux Sol list attributes are less, can hold very much data, generally do not need to divide the library ·　　If the amount of data is too large, you can use Login_name to sub-Library: One more database query, performance decreased by one time.

middleware is difficult to grasp the merits of data join, and it is difficult to achieve high performance, the service reads as few as possible using the multi-table join.Problems and coping strategies after the sub-list of libraryThe Library sub-table is mainly used to deal with the two common scenarios of the current Internet: massive data and high concurrency

, it can solve the performance bottleneck caused by the large sheet size and increase the concurrency support. Be careful to choose the right split key to plan ahead. Business reads as few as possible with multiple table joins, the same transaction avoids cross-sharding. Query criteria as far as possible with the split key, to avoid the full shard table scan.The database middleware DDM manages the underlying database storage engine in a cluster manner, which is very convenient for users to use.

above architecture, we have updated our code to implement non-disruptive services while addressing some of the single node issues. Later a period of time business to do promotional activities, business volume explosion, database data volume into exponential growth. The database load has been high. The current architecture has been unable to meet the business requirements, and then put forward to the database data on the hot and cold data splitting and data read and write separation (you can con

In the iOS8 environment, when you disable the positioning service General switch, you cannot add the APP positioning sub-options to the positioning permission list. ios8appKey points:-(void) locationManager :( CLLocationManager *) manager didChangeAuthorizationStatus :( clthorizationstatus) when the APP calls the startUpdatingLocation method for the first time in iOS7, the system will automatically add the

, and even can be serviced.Vertical Sub-tableConcept: Based on fields, the fields in the table are split into different tables (primary and extension tables), depending on the activity of the fields.Results:The structure of each table is different;The data for each table is not the same, in general, the field of each table has at least one column intersection, is usually the primary key, used to correlate the data;The aggregate of all the tables is th

Collection sub-interface (List/Set/Queue/SortedSet), queuesortedsetMain sub-interfaces of Collection: List: stores duplicate content. Set: duplicate content cannot be stored. All duplicate content is differentiated by hashCode () and equals (). Queue: Queue Interface SortedSet: sorts data in a set.

Label:This article will mainly introduce some common global primary key generation strategies, and then highlight a very good global primary key generation scheme used by Flickr. For the split strategy and implementation details of the sub-list (sharding), refer to the previous article in the series: Database Library sub-table (sharding) series (i) Split implemen
