QUESTION
Updated for better hardware
I have the following simplified schema in Postgres12 whereby a dataset has many cfiles and each cfile has property_values stored as jsonb:
...ANSWER
Answered 2021-Mar-18 at 21:46I think you will have a tough time doing much better with the current schema. Could you normalize the data do you have a table with one row per (tid,"Sample Names",id)
combo, or perhaps just one row per unique ("Sample Names") or per (tid,"Sample Names")
?
Although I don't think there is a generic answer to "As well as filtering by columns from the other joined tables". An answer would depend on how selective the filter is and whether it is indexable.

is a set returning function and should be used in the FROM
clause. Using it in the SELECT list makes things unnecessarily complicated:
QUESTION
I have a single SELECT that queries both regular postgres tables and a jsonb column. When I SELECT the entire jsonb column, the query is fast (574 ms). However when I instead select a top-level path of the same jsonb column, the query slows down by 6x (3241ms). My final query needs to access the string array values from 4 of these top-level jsonb paths, which slows the query right down to 5 seconds.
I have about 50K records in the cfiles
table and the jsonb column cfiles.property_values
is structured like this:
ANSWER
Answered 2021-Jan-21 at 15:50Your slow query is deTOASTing the large jsonb data for all 44255 rows, and then carrying the parsed-out values through the sort to pick out the top 20 rows. (I don't know why it does the deTOASTing eagerly like that). So 44235 JSONB were deTOASTed just to be thrown away.
Your fast query is (presumably) returning TOAST pointers from the hash join, sorting the rows with those small pointers, and then deTOASTing only the 20 survivors. In the case of EXPLAIN ANALYZE, it doesn't even deTOAST the survivors, it just throws the pointers away.
That is the "why", as for what to do about it, if you truly can't alter any of the query below the very top part, I doubt there is anything you can do about it on the server side.
If you can modify the query more substantially, then you can improve the run time with a CTE. Have the CTE select the entire jsonb, and then the select on the CTE pulls the value out of it.
QUESTION
I'm trying to watching file created event on Directory using FileSystemWatcher of Spring boot devtools filewatch package It's work fine when catch created event when file be written. But I facing a problem when write file with high frequency. FileSystemWatcher will waiting until all files be written then fire created event for each file.
So, I want FileSystemWatcher will fire created event when each file written, not wait to all file be written then fire events. How can I do that. Here is my code:
- Watching Configuration
ANSWER
Answered 2020-Dec-16 at 08:58I've found the root cause by the folder which store file be locked by writer process. With high frequency, it will be locked until writer complete. So that, I've change my code to another way. I use common.io package to watching folder and just lock file which being write not lock folder. So that, my writer app and listener app can work parallel
