Listener (post-traitements)

Objective

The Listener executes post-processing when new data is integrated into a time-series file. It compares ts_max_date.date to ts_max_date.last_date_listener to detect updates.

Processing flow

1. Listener::load() — Declares the processing to execute per ts_file
2. Listener::init() — Synchronizes the listener_main table
3. Listener::check() — Detects updated files
4. Dispatch — Calls the associated business methods

Dispatcher examples:

mysql_schemata     → Listener::updateDatabase
mysql_global_variable → Listener::afterUpdateVariable
performance_schema → Digest::integrate
ssh_hardware       → Alias::updateAlias
