(I) origins of hot and Iot The storage speed of heap organization tables is faster because sorting is not required. However, to find records that meet certain conditions, you must read all the records for filtering. At this time, the index will appear to speed up the query. The index is used to sort and store the values of a few specific fields and record the position in the table, Because the index is ordered, it is easy to query the specific record

After adding JSON support to IoT Coap, it becomes very interesting, at least we can get the results we want. In the previous article we introduced some common tools--coap the command-line toolset.COAP Client code exampleBefore we start we need to have a client-side code so that our server can return the correct data and parsevar coap = require (' Coap '); var requesturi = ' coap://localhost/'; var url = require (' URL '). Parse (RequestUri + ' id/1/')

the column (or row) is connected to the chip Input Pin pin, the output pin step outputs Low (or high in turn, depending on the pull-up or drop-down resistance in the circuit) levels, and then checks the level changes of the input pin. If there are any changes, the keys for this column and this row are pressed. This judgment is often placed in the while loop or thread, and is constantly running. For some monolithic systems, if the single function is implemented, this is understandable. However
