dbproxy-id生成器

id生成器使用的是snowflake, 需要执行 snowflake_init(region_id, worker_id); 而region_id和worker_id是在配置文件中配置的

 

network_mysqld_proxy_plugin_apply_config
位置plugins/proxy/proxy-plugin.c

 

int network_mysqld_proxy_plugin_apply_config(chassis *chas, chassis_plugin_config *oldconfig) {
    ...
    int region_id = 0;
    int worker_id = 0;
    gboolean is_complete = FALSE;
    gchar *id_generate = g_strdup(config->id_generate);


    if ( (region_id = strtoll(strsep(&id_generate, ":"), NULL, 10)) != NULL) {
         g_log_dbproxy(g_message, "##### is %s", id_generate);
        if ( (worker_id = strtoll(strsep(&id_generate, ":"), NULL, 10)) != NULL) {
            is_complete = TRUE;
        }
    }
    if (is_complete) {
         snowflake_init(region_id, worker_id);
         g_log_dbproxy(g_message, "id_generate is %s, region_id is %d, worker_id is %d", config->id_generate, region_id, worker_id);
    } else {
        g_log_dbproxy(g_critical, "id_generate is %s, region_id is %d, worker_id is %d", config->id_generate, region_id, worker_id);
    }
    ...
}
