Type Members

type Collection[X] = Iterator[X]

Type of collection used in this TSDB instance and the DAO.
Type of collection used in this TSDB instance and the DAO. The default implementation uses Iterator as a collection type. Spark based implementation uses RDD.

Query pipeline.
Query pipeline. Perform following stages:
- creates queries for DAO - call DAO query to get Collection of rows - fills the rows with external links values - extract KeyData and ValueData - apply value filters - window function application - apply aggregation: map, reduce, post-map - post reduce arithmetics - extract field values
The pipeline is not responsible for limiting. This means that collection have to be lazy, to avoid extra calculations if limit is defined.
