This chapter introduces some useful tricks if you are using gStore to implement applications.

 

Config

If you are using gStore to serve as a SPARQL Endpoint, you had better set the SPARQL_ENDPOINT macro in Util.h. In addition, all DEBUG macros in Util.h should not be used. What is more, if you do not use gStore as endpoint, but you do not need to update the database, ONLY_READ macro should be set in Util.h.

 

Backup

When running as a HTTP server, gStore has provided a backup function, and you can modify the time interval of backup procedure in Util. However, this backup utility can not take effect if the whole disk is down. As a result, you had better use multiple machines or clouds to do other backup procedures by yourself, if you are requiring a high security.

 

Query

When running as a HTTP server, gStore has set a time limit for query processing, i.e. 1 hour. You can modify this parameter in Util as you wish, but we suggest that the lowest bound is 1 minute.

 

KVstore

The efficiency of KVstore has huge impact on the performance of the whole system, and you can modify related parameters in KVstore.h, according to your demand and memory capacity.
