[jira] [Updated] (SYNCOPE-400) Poor search performance on MySQL
[ https://issues.apache.org/jira/browse/SYNCOPE-400?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Francesco Chicchiriccò updated SYNCOPE-400:
-------------------------------------------
Description:
As reported from different deployment environments, searching users and roles when using MySQL for internal storage shows very poor performance.
This is with any evidence due to bug [1], open since 2010, and is related to the "UNION ALL" construct used to define SQL search views, on which AttributableSearchDAOImpl [2] is based.
Such views definition needs to be changed in order to avoid at all the "UNION ALL" construct.
