also exist differences, summed up mainly divided into two categories:1) Ping-Pong-type heartbeat: sent by the communication party ping message timed, the other party received a ping message, immediately return to Pong reply message to each other, belonging to the request-response type heartbeat;2) ping-ping type heartbeat: Do not differentiate heartbeat request and answer, by the communication between the

votes, Sentinel need to agree on the number of master is reachable. Sentinel Monitor MyMaster 127.0.0.1 6379 2 This line is used to tell Redis to monitor a master called MyMaster, whose address is 127.0.0.1, the port is 6379, and the ticket number is 2. Here's the number of votes to explain: to raise a chestnut, Redis cluster has 5 Sentinel instances, where Master hung up, if the number of votes here is 2, indicating that 2 Sentinel think Master hung off, can be considered to be really hung up

distance of the machine, and this distance is only a logical convention discover the algorithm ideas as follows: 1. The Nodeid of a target node is randomly first 2. In the list, with relative Nodeid "distance" as the indicator, from near find the node near the node that you want to connect. And put these nodes in the nearby node collection 3. Send Findnode message 4 to each node in the nearby node collection of the target node. If no node is found near the target node, return to step 1 5. Other

As mentioned earlier, there are two different concepts about downline (down) in Redis Sentinel: The subjective downline (subjectively down, or sdown) refers to the offline judgment of the server made by a single Sentinel instance. Objective offline (objectively down, abbreviated as Odown) refers to a number of Sentinel instances in the same server to make Sdown judgment, and through the SENTINELIS-MASTER-DOWN-BY-ADDR command to communicate with each other, the resulting service The device to de

Because the server is a version of servers, it is difficult to visually see Mnesia data. So it's very confusing for beginners.Specifically in the QQ group to consult others. Others say that as long as the pong through the line, you can use RPC to operate the remote Mnesia database. Beginners too understand this meaning. Then specifically search for a bit, and finally found someone else about the two Erl node Server ping Pass article.OK, then connect t

This blog post is part of the Java Gallery (Java Gallery), and I've introduced some interesting Java projects to our readers under the Java Gallery section.It's a great thing to be a part of the Java development team and write a lot of code. At school we may not have access to a real development environment. We may not be able to do our favorite projects in the enterpr

ping-pong ball in, it can only fall in the bottom of the bowl, it is impossible to always stick on the bowl wall (--of course, you do not put the bowl diagonally). Convex problem is like the surface of the moon, table tennis fell into a hole can not come out, it is difficult to find globally optimal point. Article 4.2 introduced several convex problems more general, but I still did not understand the last kind of semidefine programming is going on. C

The simplest function of EDMA is data moving, EDMA can realize data moving from one memory to another memory; Typically, the EDMA is the data that comes in from the peripheral interface, i.e. the data that is transmitted from the MCBSP is moved to the internal space of the DSP, and the internal space of the DSP is as follows datasheet EDMA Specific usage Experience: The EDMA uses the parameter area Connection method to move the data continuously, the DMA parameter area simplest uses two par

Google's Chrome labs have collected many incredible experiments based on HTML5 Canvas and JavaScript, and the examples are unique and impressive. I never thought that combining HTML and JavaScript would make such a powerful effect.

. Optimization Let's review the workflow of the user connection described earlier. After the WebSocket is established, the client sends a request-subscription-related event (we ignore a request like Ping/pong here). Next, the client may not send any additional data throughout the lifetime of the connection. The life cycle of the connection may last for a few seconds to a few days. So for most of the time,Channel.reader () and Channel.writer
