.......P.. [ZBX-6630] faster proxy configuration synchronization This change does not affect how Zabbix server sends configuration updates to a proxy. It speeds up configuration synchronization on proxy side by reducing a number of database operations. Before this change: - updates set all fields in records to be modified, - special preprocessing for "hostmacro" and "items" table modifies all records in the table. After this change: - updates set only fields whose values differ, - special preprocessing for "hostmacro" and "items" table modifies only records and fields which are going to be updated and can cause conflict. - special preprocessing is added for "hosts_templates" table to avoid conflicts on 'hostid, templateid' index.
