我正在支持Grails Web应用程序,该应用程序使用AmCharts为客户端显示不同的视觉效果.在其中一个选项卡上有三个图表,每个图表根据不同的度量从数据库中返回前十个,因此只有十行.完成需要4-5次甚至更长时间.查询在10秒内在DB上运行.

调用以下服务方法以返回结果:

List fetchTopPages(params, Map querySettings, String orderClause) {
    if(!((params['country'] && params['country'].size() > 0) || (params['brand'] && params['brand'].size() > 0) || (params['url'] && params['url'].size() > 0))) {
        throw new RuntimeException('Filters country or brand or url not selected.')
    }
    Sql sql = new Sql(dataSource)
    sql.withStatement { stmt -> stmt.fetchSize = 100 }
    Map filterParams = acquisitionService.getDateFilters(params, querySettings)
    ParamUtils.addWhereArgs(params, filterParams)
    String query = "This is where the query is"

    ParamUtils.saveQueryInRequest(ParamUtils.prettyPrintQuery(query, filterParams))
    log.debug("engagement pageviews-by-source query: " + ParamUtils.prettyPrintQuery(query, filterParams))
    List rows = …
