Fixes: #15900

Utilize asynchronous compression in kafka client to reduce possibility of oversized allocation.

Backports Required

Release Notes

Improvements

Internal kafka client now uses asynchronous compression (when possible) to reduce possibility of oversized allocations and reactor stalls

Removing review I realize after seeing Rob's review that I only reviewed the first commit.

LGTM, nice !

Looks pretty good.

I wonder if it's worth raising a ticket to opportunistically replace uses of build() with build_async() where the call is already in an async scope.

@@ -31,6 +31,7 @@ class record_batch_builder {
      std::optional<iobuf>&& value,
      std::vector<model::record_header> headers);
    virtual model::record_batch build() &&;
+    virtual ss::future<model::record_batch> build_async() &&;


It doesn't look like build() is ever overridden, can these both be made non-virtual to avoid confusion?

Suggested change

nitpick (also, what are you doing with this preview, github?):

Suggested change

co_return;

}

auto batch_record_count = _config.produce_batch_record_count();

auto batch_size_bytes = _config.produce_batch_size_bytes();

_consumer(co_await do_consume());

co_return;

    }

    ss::future<> stop() {
-        try_consume(true);
+        co_await try_consume();


I guess rearming it and then cancelling it isn't too bad. In the case where produce_batch_delay == 0, it may be possible to run another round of try_consume.

To get the original behaviour:

Suggested change

co_await try_consume();

_timer.set_callback([]() {});

co_await try_consume();

+    }
+
+    /// \brief Validates that the size threshold has been met to trigger produce
+    inline bool threshold_met() const {


nitpick: I don't think the inline helps you much here, it's implicitly inline. I suspect you're attempting to hint the compiler to inline the function body, there's a fair chance it will ignore you, as that's not what inline is for.

Yeah good point. I think this was muscle memory from previous work I've done.

nitpick: Same comment about inline as above.
