在 Flink SQL 中使用 SQL 客户端时,我们如何使用查询配置?

与以下链接中提到的方式相同,适用于 https://ci.apache.org/projects/flink/flink-docs-release-1.9/dev/table/streaming/query_configuration.html

想用 Idle 状态保留时间。

Flink 的 SQL 客户端可以在启动时读取一个 YAML 配置文件,这个文件可以包含空闲状态保留规范。例如,您可以通过以下方式启动客户端

sql-client.sh embedded -e sql-client-config.yaml

配置文件包含在哪里

execution:
  planner: old                      # optional: either 'old' (default) or 'blink'
  type: streaming                   # required: execution mode either 'batch' or 'streaming'
  result-mode: table                # required: either 'table' or 'changelog'
  max-table-result-rows: 1000000    # optional: maximum number of maintained rows in
                                    #   'table' mode (1000000 by default, smaller 1 means unlimited)
  time-characteristic: event-time   # optional: 'processing-time' or 'event-time' (default)
  parallelism: 1                    # optional: Flink's parallelism (1 by default)
  periodic-watermarks-interval: 200 # optional: interval for periodic watermarks (200 ms by default)
  min-idle-state-retention: 0       # optional: table program's minimum idle state time
  max-idle-state-retention: 0       # optional: table program's maximum idle state time
