The naming method for Pg XLOG files (REDOLOG) names is defined in the XLogFileName macro, the time series ID, log ID, and segment ID are composed of eight hexadecimal numbers. For example, 000000000000000000008f. # Define XLogFileName(Fname, tli, log, seg)\ Snprintf (fname, MAXFNAMELEN,"% 08X % 08X % 08X", Tli, log, seg) Different segment IDs correspond to different physical XLOG log files. Log IDs are logical concepts and contain multiple physical XLOG files. The initial size of the Pg XLOG fil

The following code implements the putblock file block. You must call putblocklist to write the file to the end. The main code is as follows: (putblock returns the blockids array and passes the array to putblocklist) // Put block - upload a block (p

Simply put, virtual storage (Storage virtualization) means that multiple storage media modules (such as hard drives, RAID) are centrally managed through a certain set of methods, and all enclosures are managed in one storage pool. This can be a variety of storage devices uni

A comparison between sequential storage structure and chain-type storage structure Advantages and disadvantages in order to store, adjacent data elements are also adjacent to the storage address (logical and physical unity); The address of the available storage units in memory must be contiguous. Advantages: Large

This section mainly introduces the data storage and management in the DN, we know that logically we store the data into the HDFs file system, but the specific data on each DN is how to store it, which involves several relatively large class datastorage, Storage, Fsdataset and so on. First read the DN source code this part is not very clear, now the idea, also calculate to just start to see some tips of chil

Gradual evolution of cloud storage and data center Storage For any enterprise, it is unlikely that 100% of their data will be migrated to cloud services. However, most enterprises are willing to use the advantages of cloud storage to store data. Using cloud storage as a hybrid cloud means that the data stored in the d

When an administrator first starts using the Docker container, it is often surprising that the container itself takes a non-persistent storage. When the container is removed, the container's storage is also removed. Of course, if there is no way to implement permanent storage, the use of container applications will be very limited. Fortunately, some methods can i

, the sub-graph must have a ring. A graph can have many different spanning trees.all spanning trees have the following common characteristics:1, the number of vertices of spanning tree is the same as the number of vertices of graphs;2. Spanning tree is a minimal connected sub-graph of graphs;3. The spanning tree of a connected graph with n vertices has a n-1 edge;4, the path between any two vertices in the spanning tree is unique;5, in the spanning tree and add an edge will inevitably form a loo
