Обсуждение: vacuum / analyze parent tables on partitioned tables.
Hello,
I wrote a script to make sure all tables are vacuumed and analyzed every evening. This works very well, but I have a question:table_name ; avg runt time; max run time; min run time
"f_transaction_1";"00:03:07.8";"00:03:10";"00:03:03"
"f_transaction";"00:02:19.8";"00:02:25";"00:02:16"
f_tranaction_1 is 15GB data + 12GB of indexes. (I know, a lot of indexes). f_tranaction is totally empy, but also contains all indexes. Which means 0B table zise, and 140kB index size.
Does anyone has an idea why in this case the vacuum/analyze takes almost as long on the parent table as on the biggest child table? (the other child tables are smaller, and their vacuum/analyze time is much shorter).
wkr,
