Module: ClickhouseNative::Logging

Included in:
Client
Defined in:
lib/clickhouse_native/logging.rb

Overview

Sequel-style logging wrapper. Prepended onto Client so it fires for the raw C-level execute/query/query_value/query_each/insert_block calls.

client = Client.new(..., logger: Rails.logger)
client.query("SELECT 1")
# => DEBUG  -- : (0.421ms) SELECT 1

Errors are logged at ERROR with the elapsed time and exception class.
