...n the above trick for getting the right size, you might also need to put a union containing every simple type before the array, to ensure that the array itself begins with maximal alignment rather than in the middle of some other element's padding. Again, I don't believe any of this is necessary, bu...

...加一个中间层，它负责各个异构“表”之间的数据JOIN和UNION等计算，并且隔离前端产品和后端存储，提供统一的数据查询服务。这个中间层就是glider（如图8所示）。 缓存是系统化的工程 除了起到隔离前后端以及异构“表”之...

...ve, as in when SQL Server does internal sorts such as during a distinct or union operation, or if it chooses a merge during it's query plan, etc. Move could also mean the time it takes to get the data from the server to my local pc or to another computer or wherever it is going to be consumed.

...ism supersedes much of PCL UPDATE Jul 10 2013: Excellent state of the PCL union summary blogpost from @shanselman with lots of concrete examples, screenshots and links. Puts any other answer here in the shade. UPDATE May 20 2013: Very practical coverage of practical application and implications...

... public: // all 83 member functions private: size_type m_size; union { class { // This is probably better designed as an array-like class std::unique_ptr<char[]> m_data; size_type m_capacity; } m_large; std::array<char,...

...td::string, variant_type (*)()> map_type; A boost::variant is like an union. It knows which type is stored in it by looking what object was used for initializing or assigning to it. Have a look at its documentation here. Finally, the use of a raw function pointer is also a bit oldish. Modern C+...

...extremely fast, memory-cheap and disk-cheap. This is provided by AUFS, a union filesystem that Docker depends on. You could set up AUFS yourself manually with LXC, but Docker uses it as a standard. 5) Logging: the standard streams (stdout/stderr/stdin) of each process container is collected an...

...cky part about making an ISet<T> concurrent is that the set methods (union, intersection, difference) are iterative in nature. At the very least you have to iterate over all n members of one of the sets involved in the operation, while locking both sets. You lose the advantages of a Concur...

...ll (because they have thread-local piles). At the end, all workers need to union their pile-sets. I believe that can be done in O(log (worker count * piles per worker)) if the workers form an aggregation tree. What about the element distinctness problem? As the article states, the element distinct...
