slow drop table
Hi All,
We are currently doing a POC of apache ignite:
Deployed in 10 bare metal servers each:
40vcores
256GB RAM
We got a table with 38 million rows, and when executing a drop table
statement, the query executes about an hour. How did this happen? Any idea
how to improve the drop table performance?
BR,
Anung

Hi Alex,
Thank you for replying.
We gave Ignite 128gb heap space, and there is no other table beside that
sample table.
We will try some of the optimizations from the guide, will update later
Thanks,
Anung

Hi,
You need to examine the logs to see where the delay is.
Check that you have enough memory, and that the system is not thrashing
(constantly going to disk to retrieve data).
Look into Garbage Collector logs to get more insight into your app
performance.
