7.18. Local File Connector#

The local file connector allows querying data stored on the local file system of each worker.


To configure the local file connector, create a catalog properties file under etc/catalog named, for example, with the following contents:

Configuration Properties#

Property Name Description
presto-logs.http-request-log.location Directory or file where HTTP request logs are written
presto-logs.http-request-log.pattern If the log location is a directory, this glob is used to match file names in the directory

Local File Connector Schemas and Tables#

The local file connector provides a single schema named logs. You can see all the available tables by running SHOW TABLES:

SHOW TABLES FROM localfile.logs;


This table contains the HTTP request logs from each node on the cluster.
