MAINTAINING SMOOTH METADATA LOG DESTAGING AND BURST TOLERANCE - A simplified explanation of the abstract
This abstract first appeared for US patent application 17872234 titled 'MAINTAINING SMOOTH METADATA LOG DESTAGING AND BURST TOLERANCE
Simplified Explanation
The technique described in this patent application is focused on processing changes in metadata. It involves using two tablets, one for ingesting metadata changes and the other for destaging previously ingested metadata changes. Each tablet is partitioned into a reserved space and a regular space, forming separate memory pools.
The process begins with the first tablet designated for ingesting metadata changes and the second tablet designated for destaging previously ingested metadata changes. Metadata changes are ingested into the first tablet, while previously ingested changes are destaged from the second tablet.
When the first tablet becomes full, a switch operation is performed. This operation designates the second tablet to ingest metadata changes and the first tablet to destage previously ingested metadata changes.
Potential applications of this technology:
- Data storage systems that require efficient processing of metadata changes
- Database management systems that handle frequent updates to metadata
Problems solved by this technology:
- Efficient management of metadata changes in a memory-constrained environment
- Minimizing the impact of metadata processing on system performance
Benefits of this technology:
- Improved performance and efficiency in processing metadata changes
- Increased capacity for handling large volumes of metadata updates
- Reduced system downtime during metadata processing operations
Original Abstract Submitted
A technique is directed to processing metadata changes. The technique involves designating a first tablet to ingest metadata changes and a second tablet to destage previously ingested metadata changes, the first tablet being partitioned into a first reserved space and a first regular space that form a first memory pool, and the second tablet being partitioned into a second reserved space and a second regular space that form a second memory pool. The technique further involves, while the first tablet is designated to ingest metadata changes and the second tablet is designated to destage previously ingested metadata changes, ingesting metadata changes into the first tablet and destaging the previously ingested metadata changes from the second tablet. The technique further involves, when the first tablet becomes full, performing a switch operation that designates the second tablet to ingest metadata changes and the first tablet to destage previously ingested metadata changes.
