Joins two sets of logs based on specified criteria and creates new logs with the joined data. The join operation is similar to SQL joins, allowing inner, left, right, and outer joins between two sets of logs filtered by the criteria in pair_of_args. Args: pair_of_args: List of two dictionaries containing filtering criteria for logs to join. Each dictionary can include context, filter_expr, from_ids, etc. join_expr: SQL expression for the join condition using aliases A and B (e.g., ‘A.user_id = B.user_id’) mode: Type of join to perform (‘inner’, ‘left’, ‘right’, or ‘outer’) new_context: Name for the new context where joined logs will be stored columns: Optional list of column names to include in the joined result project: Name of the project containing the logs Returns: JSON response with info about the join operation

Authorizations

​
Authorization
string
required
Bearer authentication header of the form Bearer <token>, where <token> is your auth token.

​
Body

​
pair_of_args
[object]
required
Two sets of filtering criteria for logs to join
​
join_expr
string
required
SQL expression for join condition using aliases A and B
​
mode
string
required
Join type: ‘inner’, ‘left’, ‘right’, or ‘outer’
​
new_context
string
required
Name for the new context where joined logs will be stored
​
columns
object | null
Optional dictionary mapping source columns to new column names for the result. The key is the source column (e.g., ‘A.user_id’) and the value is the desired alias in the new log (e.g., ‘user_identifier’). If omitted, all columns will be selected and prefixed with ‘A_’ or ‘B_’.

project
string
required
Name of the project
