Product Specifications

Technical details and manufacturing context for Transaction Log Manager

Definition

The Transaction Log Manager is a critical sub-component of a Storage Manager system responsible for maintaining a chronological record of all data operations (reads, writes, modifications, deletions). It ensures data integrity, supports recovery procedures, and provides an audit trail for transaction history within storage systems. This component operates by intercepting transaction requests, generating timestamped log entries with operation details (transaction ID, data location, operation type, before/after states), and persistently storing these entries. It typically implements write-ahead logging (WAL) protocols to ensure changes are logged before being applied to the main data store, enabling rollback and recovery functions. The Transaction Log Manager is designed for integration into industrial storage systems, with parameters such as log capacity (100,000–1,000,000 entries), throughput (1,000–10,000 transactions per second), latency (1–10 ms), and log retention period (30–365 days). It guarantees data integrity of 99.999% under normal operation. The component operates within an ambient temperature range of 0–50 °C and storage humidity of 10–90% RH (non-condensing). Typical power consumption is 5–20 W, with an input voltage range of 12–24 V DC. It supports SATA–SAS interfaces and is available in 2.5–3.5 inch form factors. The mean time between failures (MTBF) is 1,000,000–2,000,000 hours. Compliance with safety and EMC standards is referenced to IEC 62368-1, with CE–FCC markings as applicable. As a software component, the primary material on file is software code. All listed values are directory reference ranges and must be verified with the legal manufacturer or supplier for the specific model and application.

Working Principle

The Transaction Log Manager intercepts transaction requests from the storage system. For each transaction, it generates a timestamped log entry containing the transaction ID, data location, operation type, and before/after states. These entries are persistently stored using write-ahead logging (WAL), ensuring that changes are logged before being applied to the main data store. This enables rollback and recovery in case of failures. The manager also manages log rotation and archival based on configured retention periods.
