Examples of net.opentsdb.core.TSSubQuery

net.opentsdb.core.TSSubQuery
Represents the parameters for an individual sub query on a metric or specific timeseries. When setting up a query, use the setter methods to store user information such as the start time and list of queries. After setting the proper values, add the sub query to a {@link TSQuery}.
When the query is processed by the TSD, if the {@code tsuids} list has oneor more timeseries, the {@code metric} and {@code tags} fields will be ignored and only the tsuids processed.
Note: You do not need to call {@link #validateAndSetQuery} directly asthe {@link TSQuery} object will call this for you when the entire set of queries has been compiled. Note: If using POJO deserialization, make sure to avoid setting the {@code agg}, {@code downsampler} and {@code downsample_interval} fields. @since 2.0
