I recently tested data processing performance using storm. Topology Structure: spout outputs 0.8 million data (in CSV format); bolt1 parses CSV data and splits each information segment; bolt2 is summarized by a field in bolt1, and is written into the database after the count is accumulated (loading Trigger frequency: 60 s ). Concurrency configuration: spout task (1) Executor (3); bolt1 excutor/task (16); bolt2 excutor/task (8 ); Workers (8); storm slot (8) Hardware configuration: 8 CPU, 16g

from net | NULL 2.2 interactive_timeout wait_timeout Let's take a look at the official documentation. From the documentation, wait_timeout and interactive_timeout both indicate inactive connection timeout times, when the connection line starts, wait_timeout is set to one of the two values based on the interaction mode or non-interaction mode. If we runmysql -uroot -pAfter logging on to mysql, wait_timeout is set to the value of interactive_timeout. If we do not perform any operation within the

, the choice between long and short connections depends on the situation. First, if you use a long connection and do not have any operations on the database for a long time, after the timeout value, the MySQL server closes the connection, and the client gets an error similar to the "MySQL server has gone away" when it executes the query. After using Mysql_real_connect to connect to the database, use the Mysql_options (mysql, Mysql_opt_reconnect, ...) to set the automatic

Databases that are constantly updated and optimized can run at a faster rate. However, the idea of moving a database directly from a smaller disk to another larger disk is not possible. Before you transfer the database, you must disconnect all operations from the database. You can use the sp_detach_db stored program to isolate the database from SQL Server 2000, which enables offline operation of the database. You can also run another stored program sp_attach_db to

One, the error: "can ' t swap PDO instance while within transaction" By querying the Laravel source code, you can confirm that the exception was thrown in the setPdo method: Literally, this error occurs because the database connection has been switched on when the transaction is turned on. Sometimes, however, this error can occur even if there is no explicit switch to the database connection in the code. For example, when executing a query statement error, the system will tryAgai

Apple computers sometimes have a wireless connection, sometimes it may be a problem with the system network components, but also may be the current system of some bugs caused, but also may be other factors, such as routers. Here's a quick introduction to some of the ways that Apple computers can't connect to wireless. 　　Try to turn off the MAC's wireless network 1, when found that the MAC computer can not connect to the wireless network, we can first try to shut down the wireless network. Clic

shown in Figure 1. It shows that there are multiple wireless networks available, double-click Tp-link to connect to the wireless router, and then connect successfully. (2) Open IE Browser, enter IP address: 192.168.1.1 (wireless router default LAN IP address). (3) Login to the wireless Router Management interface (username: admin, Password: admin). Click the LAN port settings option under Network Parameters on the left side of the interface to set the IP address to 192.168.1.8 and save. (4

connection is disconnected, slave will attempt to reconnect master. When the following conditions are met, incremental synchronization occurs after the connection is repeated:1. The master server ID for the slave record is the same as the master server ID that is currently being connected2. Slave's replication offset is higher than Master's offset. Like slave is 1000, master is 1100.3. The data specified by the replication offset for slave is still s

is set by the app that created the session. If the server does not receive any requests within the time-out period, the corresponding session expires. Once a session has expired, it cannot be reopened, and any ephemeral znode associated with that session will be lost. Sessions usually persist for a long time, and session expiration is a rare event, but it is still important for the app to handle session expiration. A ping request (also known as a heartbeat) can be sent through the client to kee
