[asterisk-bugs] [JIRA] (ASTERISK-28195) stasis: Don't create subscription change messages if noone cares

[Joshua C. Colp (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-28195?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=245645#comment-245645 ] 

Joshua C. Colp commented on ASTERISK-28195:
-------------------------------------------

Ideally whether a topic has any interested subscribers for these messages would be calculated ahead of time so the act of checking whether the messages need to be created is merely looking for a non-zero variable on the topic (to keep that fast).

>          Issue Type: Bug
>      Security Level: None
>          Components: Core/Stasis
>    Affects Versions: 13.23.1, 16.0.0
>            Reporter: Joshua C. Colp
>            Severity: Minor

> As part of working on some statistics code I determined that for the most part Stasis messages in Asterisk are actually used - except for one: stasis_subscription_change_type. With filtering now a thing it seems as though about 50% of these messages aren't consumed by any subscriber.
> This change is for making the creation smarter, so we only create those messages if a subscriber is interested in them.
