Query Service

可以运行Flink流作业来启动表的查询服务，当QueryService存在时，Flink Lookup Join将优先从中获取数据，这将有效地提高查询性能。

Flink SQL

CALL sys.query_service('database_name.table_name', parallelism);

Flink Action

<FLINK_HOME>/bin/flink run \/path/to/paimon-flink-action-0.7.0-incubating.jar \query_service \--warehouse <warehouse-path> \--database <database-name> \--table <table-name> \[--parallelism <parallelism>] \[--catalog_conf <paimon-catalog-conf> [--catalog_conf <paimon-catalog-conf> ...]]
