Accelerable

join is always accelerable if the input is accelerable. A dataset that only uses accelerable verbs, can be accelerated, making queries on the dataset respond faster.

Examples

join [email protected], hostname:@host.name

Temporal inner join with dataset ‘host’, and extract the ‘name’ column from that ‘host’ table, calling the new column ‘hostname’ in the output.
