Spring Cassandra 3.0.1.RELEASE(Datastax 4.6+) 日志查询

Question

我正在使用最新版本的 spring data cassandra，它使用 datastax 4.6

在旧版本中，有一种方法可以使用 QueryLogger 和 Cluster

记录较慢和正常的查询

但是我无法找到记录查询和更新版本所用时间的方法

Answer 1

在较新的版本中，QueryLogger 不再可用，它已被 RequestTracker

取代

Java 驱动程序提供了一个 RequestTracker 接口。您可以指定您的实现 通过配置属性来拥有或使用提供的 RequestLogger 实现 datastax-java-driver.advanced.request-tracker 命名空间。 RequestLogger 跟踪每个 查询您的应用程序执行并具有启用成功、失败和慢速日志记录的选项 查询。使用慢查询记录器来识别不在您定义的性能范围内的查询。

配置：

datastax-java-driver.advanced.request-tracker {
  class = RequestLogger

  logs {
    # Whether to log successful requests.
    success.enabled = true

    slow {
      # The threshold to classify a successful request as "slow". If this is unset, all
      # successful requests will be considered as normal.
      threshold = 1 second

      # Whether to log slow requests.
      enabled = true
    }

    # Whether to log failed requests.
    error.enabled = true

    # The maximum length of the query string in the log message. If it is longer than that, it
    # will be truncated.
    max-query-length = 500

    # Whether to log bound values in addition to the query string.
    show-values = true

    # The maximum length for bound values in the log message. If the formatted representation of
    # a value is longer than that, it will be truncated.
    max-value-length = 50

    # The maximum number of bound values to log. If a request has more values, the list of
    # values will be truncated.
    max-values = 50

    # Whether to log stack traces for failed queries. If this is disabled, the log will just
    # include the exception's string representation (generally the class name and message).
    show-stack-traces = true
}
