In computer programming, a flag field is an integer interpreted as a sequence of boolean bits, each called a "flag". Flags are typically found as members of a defined data structure, such as a database record, and the meaning of the value contained in a flag will generally be defined in relation to the data structure it is part of. In many cases, the binary value of a flag will be understood to represent one of several possible states or statuses. In other cases, the binary values may represent one or more attributes in a bit field, often related to abilities or permissions, such as "can be written to" or "can be deleted". However, there are many other possible meanings that can be assigned to flag values. One common use of flags is to mark or designate data structures for future processing. Within microprocessors and other logic devices, flags are commonly used to control or indicate the intermediate or final state or outcome of different operations. Microprocessors typically have, for example, a status register that is composed of such flags, and the flags are used to indicate various post-operation conditions, such as when there has been an arithmetic overflow.

A method implemented by a network edge node including adding a first header including a flags field and a data field including a first metadata to a first packet. The network edge node sets a first flag in the flags field of the first header to a first value to indicate that the first packet is a forward flow packet. The network edge node transmits the first packet towards a second network edge node. The network edge node receives a second packet including the first metadata in the data field and a second flag in the flags field set to the first value to indicate that the second packet is a reverse flow packet. The network edge generates a second metadata corresponding to receipt of the second packet and transmits an export message that includes the first metadata and second metadata toward a controller.

A method, device and medium for WAL log compression under PostgreSQL stream replication
This application discloses a WAL log compression method, device, and medium under PostgreSQL streaming replication, belonging to the database field. The method includes: reading configuration parameters and establishing a streaming replication connection when the master database starts up, obtaining network I / O load values in real time, and calculating the predicted WAL log generation rate based on the transaction processing rate to estimate future bandwidth requirements. When the network I / O or predicted bandwidth requirements reach a preset threshold, samples of the original WAL log data are extracted and compared using multiple algorithms for rapid compression. The optimal compression algorithm is dynamically selected for adaptive compression processing, and the corresponding compression flag field is set; otherwise, the data is transmitted directly in an uncompressed manner. The standby database completes the corresponding decompression or direct writing by parsing the compression flag field. This invention achieves a dynamic balance between network bandwidth and CPU resources through a dual mechanism of load prediction and content awareness, effectively reducing master-standby replication latency and improving the adaptability and overall operating efficiency of the streaming replication system in complex production environments.
