It uses the MySQL client library API as a data transport, treating remote tables as if they were located on the local server. Each Federated table that is defined there is one .frm (data definition file containing information such as the URL of the data source). The actual data can exist on a local or remote MySQL instance.
So if two tables are T1 and T2, SELECT * FROM T1, T2 will result in every combination of T1 rows with every T2 rows. E.g., if T1 has 3 rows and T2 has 5 rows, then 15 rows will result. Although not in standard, most DBMS allows using a select clause without a table by pretending that an imaginary table with one row is used.
Percona Server for MySQL is an open source relational database management system (RDBMS). It is a free, fully compatible drop in replacement for Oracle MySQL . The software includes a number of scalability, availability, security and backup features only available in MySQL's commercial Enterprise edition. [ 2 ]
The Lasso Server application server runs as a system service and receives requests from the web server through FastCGI. It then hands the request off to the appropriate Lasso Instance, which formulates the response. Multiple individual instances are supported, allowing one server to handle multiple sites, each as separate processes.
In January 2006, well after version 2.1 was established, RFC 4253 specified that an SSH server supporting 2.0 as well as prior versions should identify its protocol version as 1.99. [26] This version number does not reflect a historical software revision, but a method to identify backward compatibility .
Figure 1: Example two-port network with symbol definitions. Notice the port condition is satisfied: the same current flows into each port as leaves that port.. In electronics, a two-port network (a kind of four-terminal network or quadripole) is an electrical network (i.e. a circuit) or device with two pairs of terminals to connect to external circuits.
A Serial ATA port multiplier is a unilateral splitting device. While it allows one equipped port to connect up to 15 disks, the bandwidth available is limited to the bandwidth of the link to the controller, as of 2012 1.5, 3, or 6 Gbit/s. [3]
A Web server is server software, or hardware dedicated to running said software, that can satisfy World Wide Web client requests. A web server can, in general, contain one or more websites. A web server processes incoming network requests over HTTP and several other related protocols.
