Windows are used to batch events based on some conditions. Wisdom 0.0.1 supports the following windows:

• Window.length
• Window.lengthBatch
• Window.externalTimeBatch
• UniqueWindow.lengthBatch
• UniqueWindow.externalTimeBatch

Java API:

app.defineQuery("query1")
    .from("StockStream")
    .window(Window.lengthBatch(3))
    .insertInto("OutputStream");

Wisdom Query:

from StockStream
window.lengthBatch(3)
insert into OutputStream;
