Grails标准运行太慢

Question

以下标准的运行速度令人无法接受。如果没有在表的主键或索引上输入太多细节，您是否看到任何可以使其运行更快的特定内容？

def results = OpportunityApplication.createCriteria().list() {

            isNull('dateDeleted')

            or {
                opportunityInst {
                    isNull('dateDeleted')
                    opportunity {
                        isNull('dateDeleted')
                        gt('advertisingEndDate', new Date())
                        eq('useOrgAsContact', false)
                    }
                    opportunityLocation {
                        isNull('dateDeleted')
                        eq("email", user.email)
                    }
                }

                if (isPartner)
                {
                    opportunityInst {
                        isNull('dateDeleted')
                        opportunity {
                            isNull('dateDeleted')
                            gt('advertisingEndDate', new Date())
                            eq('useOrgAsContact', true)
                            organisation {
                                isNull('dateDeleted')
                                eq("email", user.email)
                            }
                        }
                    }
                }
            }

        }

Answer 1

根据我的标准进行优化非常简单。我所要做的就是将重复的位移动到共享片段中，如下所示

opportunityInst {
                isNull('dateDeleted')
                opportunity {
                    isNull('dateDeleted')
                    gt('advertisingEndDate', new Date())
                }
                or {
                    if (isPartner)
                    {
                        opportunity {
                            eq('useOrgAsContact', true)
                            organisation {
                                isNull('dateDeleted')
                                eq("email", user.email)
                            }
                        }
                    }
                    and {
                        opportunity {
                            eq('useOrgAsContact', false)
                        }
                        opportunityLocation {
                            isNull('dateDeleted')
                            eq("email", user.email)
                        }
                    }
                }
            }
