reindex rule product catalog

Question

sorry for my language... I have a little problem with magento 2.3 . I use product catalog rules to create discounts for groups of users. once every day or two, there is no specific time or in any case I cannot understand why, the product rules no longer work. If I connect with a user who is associated with a group with rules, I do not see any product discounts. The only solution is to "reindex" and "flush" magento from terminal.

I created a cron job that reindexes and flushes cache every day, but that's not enough.

Every time I have to receive messages from my customers who do not see the discounts and at that moment I have to reindex.

Do you know which event triggers the loss of the rules ?? how can i solve?

Thanks for all.

Answer 1

The way you describe it is typical to your cron table being stuck.

It seems your database uses a prefix mg_

If you login to mysql and do the following select * from mg_cron_schedule where status not in ('success', 'pending');

If the result shows many results, then you will likely need to check the health of your cron processes.

Thanks for the reply. I ran the query and these results came out.

the messages column says:

id 792: " SQLSTATE[42S02]: Base table or view not found: 1146 Table 'aa_mg3.mg_magento_bulk' doesn't exist, query was: DELETE FROM mg_magento_bulk WHERE (start_time <= '2019-02-08 12:53:14') "

id 831: " SQLSTATE[42S02]: Base table or view not found: 1146 Table 'aa_mg3.mg_inventory_stock' doesn't exist, query was: SELECT mg_inventory_stock.stock_id FROM mg_inventory_stock"

What should I do? is this the cause of why i have to reindex and flush manually?
