Accelerable¶
fulljoin 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¶
fulljoin on([email protected]), hostname:@host.name
Temporal full join with dataset ‘host’, and extract the ‘name’ column from that ‘host’ table, calling the new column ‘hostname’ in the output.
