[improve][broker] Replaced checkBackloggedCursors with checkBackloggedCursor(single subscription check) upon subscription #19343

heesung-sn · 2023-01-28T05:32:18Z

Motivation

Related to #19341,

When there are many concurrent subscriptions in a topic(10k> ), brokers' performance degrades because checkBackloggedCursors() iterates all subscriptions for each subscribe call.

Running checkBackloggedCursors() in the subscription path is redundant as checkBackloggedCursors() is called in updateStats() every statsUpdateFrequencyInSecs(by default 1min).

Modifications

Replaced checkBackloggedCursors() with checkBackloggedCursor() in subscribe() call. Upon the subscription creation, this will only check the backloggedCursor from the subscription to create instead of checking all the subscriptions.

Question:
When this logic is removed, if the cursor has no consumers and it is set to an inactive state by updateStats. Will a new subscription activate the cursor?

merlimat

I think it would be better to call it only for the single subscription, instead of for all of them

heesung-sn · 2023-01-28T21:33:33Z

Also,

If we still want to call this operation, checkBackloggedCursors asynchronously but more frequently, we could run such async operations in a separate thread and run it more frequently, every x milliseconds(out side of updateStats), if there are any requests (with deduplication).

// Example
'''
AsyncOpManager:

var dedupedOps

void schedule(Op op) // dedup/add op to dedupedOps.

void start(){

while(true)
// wakeup every x milliseconds s(configurable) and run the deduped ops

}

I think it would be better to call it only for the single subscription, instead of for all of them

Updated the code to check the single subscription.

…dCursor(single subscription check) from subscribe
