在Flink SQL中使用SQL客户端时,我们如何使用查询配置?
与下面的链接中提到的方式相同 https://ci.apache.org/projects/flink/flink-docs-release-1.9/dev/table/streaming/query_configuration.html
要使用空闲状态保留时间。
答案 0 :(得分:1)
Flink的SQL客户端在启动时可以读取YAML配置文件,并且该文件可以包含空闲状态保留规范。例如,您可以通过
启动客户端 sql-client.sh embedded -e sql-client-config.yaml
配置文件所在的位置
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
