> Project: Syncope
> Issue Type: Bug
> Components: core
> Affects Versions: 1.0.8, 1.1.2
> Environment: MySQL
> Reporter: Francesco Chicchiriccò
> Assignee: Francesco Chicchiriccò
> Priority: Critical
> Fix For: 1.1.3, 1.2.0
>
>
> 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.
