housekeeper table in zabbix db

[FrankieWildie]

Hello.
There is a table housekeeper.ibd inside zabbix mysql database

mysql> describe housekeeper;
+---------------+---------------------+------+-----+---------+-------+
| Field         | Type                | Null | Key | Default | Extra |
+---------------+---------------------+------+-----+---------+-------+
| housekeeperid | bigint(20) unsigned | NO   | PRI | NULL    |       |
| tablename     | varchar(64)         | NO   |     |         |       |
| field         | varchar(64)         | NO   |     |         |       |
| value         | bigint(20) unsigned | NO   |     | NULL    |       |
+---------------+---------------------+------+-----+---------+-------+
4 rows in set (0.07 sec)

I need to clean up it may be wipe at all. Is it safe to delete data here?

There is some information in the article https://zabbix.org/wiki/Docs/howto/mysql_partitioning

1. Even with the housekeeping for items disabled, Zabbix server and web interface will keep writing housekeeping information for future use into the housekeeper table. To avoid this, you can set ENGINE = Blackhole for this table:

Some thoughts:

1. What is future use from housekeeper table?
2. If houskeeper is disabled and ENGINE is set to Blackhole, is it safe to delete data?
