Abstract
In a method for improving performance of a database, create, in a memory, an instance of a segment of data corresponding to a segment of data in a database on a persistent file system. The segment of data in the database on the persistent file system is expected to experience a high plurality of reads and writes during a certain time period. Receive a request to modify the segment of data in the database on the persistent file system. Modify the instance of the segment of data in the memory.
Claims20
A computer implemented method for improving performance of a database, the method comprising:
- creating, in a volatile memory, an instance of a segment of data corresponding to a segment of data in a key-value database on a persistent file system that is distributed among multiple computing systems, wherein the segment of data in the key-value database on the persistent file system is (i) only a portion of a data stored in the key-value database on the persistent file system and (ii) is included in a set of data segments that are predicted to experience at least a plurality of reads and writes above a threshold during a certain time period;
- during the certain time period, responsive to receiving a request to modify the segment of data in the key-value database on the persistent file system, generating a modified segment of data by updating, by one or more processors, a content of the instance of the segment of data in the volatile memory based, at least in part, on the request;
- and
- responsive to both of (i) a time period elapsing during the certain time period and (ii) a creation, in the volatile memory, and during the certain time period, of a new instance of the segment of data corresponding to the segment of data, updating the segment of data in the key-value database on the persistent file system based on the modified segment of data.

A computer program product for improving performance of a database, computer program product comprising:
- one or more computer readable storage media and program instructions stored on the one or more computer readable storage media, the program instructions comprising:
- program instructions to create, in a volatile memory, an instance of a segment of data corresponding to a segment of data in a key-value database on a persistent file system that is distributed among multiple computing systems, wherein the segment of data in the key-value database on the persistent file system is (i) only a portion of a data stored in the key-value database on the persistent file system and (ii) is included in a set of data segments that are predicted to experience at least a plurality of reads and writes above a threshold during a certain time period;
- program instructions to respond to reception of a request to modify the segment of data in the key-value database on the persistent file system during the certain time period, by generating a modified segment of data by updating a content of the instance of the segment of data in the volatile memory based, at least in part, on the request;
- and
- program instructions to respond to both of (i) a time period elapsing during the certain time period and (ii) a creation, in the volatile memory and during the certain time period, of a new instance of the segment of data corresponding to the segment of data, by updating the segment of data in the key-value database on the persistent file system based on the modified segment of data.

- program instructions to respond to reception of a request to modify the segment of data in the key-value database on the persistent file system during the certain time period, by generating a modified segment of data by updating a content of the instance of the segment of data in the volatile memory based, at least in part, on the request;
- and
- program instructions to respond to both of (i) a time period elapsing during the certain time period and (ii) a creation, in the volatile memory and during the certain time period, of a new instance of the segment of data corresponding to the segment of data, by updating the segment of data in the key-value database on the persistent file system based on the modified segment of data.
