[D] Does the thread would reuse when one thread occur the IO block? [pulsar]

["kevinWangSheng (via GitHub)" <gi...@apache.org>]

GitHub user kevinWangSheng created a discussion: Does the thread would reuse when one thread occur the IO block?

background: when I consume the message ,I use a TTL threadlocal to store a thread variable, and when the consumer  consume the message , it will do some DB operator and use spring feign to request another interface.  And begin the consume, I remove the TTL ThreadLocal value, and reset a new value in it.

problem: I through the log find that: a message be consume and call the DB operator, the value of TTL threadlocal was be changed.


Does have any one to help me to find the answer?
