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, localfile.properties with the following contents:
.. code-block:: none
connector.name=localfile
========================================= ==============================================================
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
========================================= ==============================================================
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;
http_request_log
^^^^^^^^^^^^^^^^^^^^
This table contains the HTTP request logs from each node on the cluster.
