Red Hat Summit305.5. StreamList の使用
Camel 2.18 以降、プロデューサーは、反復子を使用してクエリーの出力をストリーミングする outputType=StreamList をサポートします。これにより、ストリーミング方式でデータを処理できます。たとえば、スプリッター EIP で各行を 1 つずつ処理し、必要に応じてデータベースからデータをロードするために使用できます。
from("direct:withSplitModel")
.to("sql:select * from projects order by id?outputType=StreamList&outputClass=org.apache.camel.component.sql.ProjectModel")
.to("log:stream")
.split(body()).streaming()
.to("log:row")
.to("mock:result")
.end();
