[jira] [Commented] (CLEREZZA-890) Use prepared statements and reuse connections in Virtuoso data operations to improve performance

["Enrico Daga (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CLEREZZA-890?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13937215#comment-13937215 ] 

Enrico Daga commented on CLEREZZA-890:
--------------------------------------

With CLEREZZA-889 all operations done by MGraphs are delegated to the DataAccess class. The DataAccess class uses a single connection and preserve prepared statements. Connections are renewed each statements 10000 executions. Different renewal policies may be implemented in the future.

> Currently, each operation is encapsulated in a dedicated connection and statement. While this is functional, it is not very performant, especially with the pattern based on atomic triple additions and deletions used by the clerezza model. Statements should be prepared, connections reused.
