Container Index Persistence via Tokenized Merging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional deduplication systems face inefficiencies in persistence operations, leading to duplicated and slow writes to persistent storage, especially when handling multiple inbound data streams, which results in high computing resource consumption and reduced performance.
Innovation Solution
A control process manages persistence operations by issuing tokens that represent persistence contracts, allowing multiple requests for the same data object to be fulfilled with a single write operation at a later time, thereby reducing duplicated writes and improving system performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional deduplication systems perform persistence operations for multiple inbound data streams, then data integrity is maintained, but duplicated write operations increase computing resource consumption and reduce performance
Solution Approach 1:
The patent combines multiple persistence requests for the same container index into a single write operation. When multiple inbound data streams request persistence of the same container index, the system merges these requests and performs one consolidated write to persistent storage, eliminating duplicated write operations while maintaining data integrity for all streams
Solution Approach 2:
The system performs preliminary identification of duplicate persistence requests before executing write operations. By analyzing incoming persistence requests and identifying those that target the same container index, the system prepares to merge these requests, preventing redundant writes before they occur and optimizing performance
2Reliability
If conventional deduplication systems write container indexes to persistent storage for each persistence request, then data persistence is ensured, but the number of write operations increases and slows down the system
Solution Approach 1:
The patent merges multiple persistence requests targeting the same container index into a single write operation. Instead of executing separate write operations for each request, the system consolidates these requests and performs one unified write to persistent storage, reducing the total time spent on persistence operations while ensuring data is persisted
Solution Approach 2:
The system creates and manages copies of container index data in memory to handle multiple persistence requests efficiently. By maintaining in-memory representations and only writing to persistent storage when necessary, the system reduces the frequency of slow persistent write operations while ensuring data persistence through controlled write operations
3Reliability
If multiple stream processes independently manage persistence operations, then each stream maintains its data integrity, but overall system resource consumption increases due to redundant operations
Solution Approach 1:
The patent implements a universal persistence management mechanism that handles persistence requests from multiple stream processes through a common interface. The system provides multi-functional capability to detect, merge, and execute persistence operations across different streams, allowing a single persistence operation to serve multiple streams simultaneously and reducing overall computing resource consumption
Solution Approach 2:
The system implements feedback mechanisms where persistence requests from multiple streams are monitored and analyzed. When the system detects that multiple streams request persistence of the same container index, it provides feedback to merge these requests, optimizing resource usage while maintaining the data integrity requirements of each individual stream

AI summary
Example implementations relate to metadata operations in a storage system. An example method includes receiving, from a first stream process, a first write request for a first container index in memory. The method further includes, in response to a receipt of the first write request, sending a first token to the first stream process without writing the first container index to a persistent storage. The method further includes receiving, from a second stream process, a first completion request for the first container index. The method further includes, in response to a receipt of the first completion request, writing the first container index from the memory to the persistent storage.
