海外TECH	DEV Community	Yet another ode to Vert.x, or how to write a performance-wise expiring map in less than 100 lines of code.	https://dev.to/sip3/yet-another-ode-to-vert-x-or-how-to-write-a-performance-wise-expiring-map-in-less-than-100-lines-of-code-5jm	Yet another ode to Vert x or how to write a performance wise expiring map in less than lines of code I ve been working with the Vert x framework for more than years but I won t stop being excited how simple lightweight and elegant it is especially the event loop thread model In this blog post I will tell you how we implemented PeriodicallyExpiringHashMap data structure in less than lines of code But first let me give you a bit of a context about why do we need it ProblemSIP is a very advanced VoIP monitoring and troubleshooting platform To provide detailed information about calls quality we need to Aggregate RTP packets into RTP streams in a real timePeriodically walk though all the RTP streams and terminate ones that haven t been updated for a certain period of time Let s stay away from telecom specific and take a look at a simplified code example class RtpStreamHandler AbstractVerticle var expirationDelay Long var aggregationTimeout Long private val rtpStreams mutableMapOf lt String RtpStream gt override fun start vertx setPeriodic expirationDelay val now System currentTimeMillis rtpStreams filterValues rtpStream gt rtpStream updatedAt aggregationTimeout lt now forEach rtpStreamId rtpStream gt terminateRtpStream rtpStream rtpStreams remove rtpStreamId vertx eventBus localConsumer lt RtpPacket gt on rtp packet event gt val rtpPacket event body handleRtpPacket rtpPacket fun handleRtpPacket rtpPacket RtpPacket val rtpStream rtpStreams getOrPut rtpPacket rtpStreamId RtpStream rtpStream addPacket rtpPacket fun terminateRtpStream rtpStream RtpStream vertx eventBus localSend on rtp stream rtpStream Now let s imagine that we constantly have a K of active RTP streams Also every second we terminate approximately a thousand of old steams but get a thousand of new ones instead In these circumstances our code doesn t look very efficient and we certainly need a better solution SolutionAs you can see from the first code snippet once an RTP stream was updated it won t be terminated at least for the next aggregationTimeout This means that we can simply do not bother about it for some time And this is the key idea behind the SIP PeriodicallyExpiringHashMap implementation class PeriodicallyExpiringHashMap lt K V gt private constructor vertx Vertx private val delay Long private val period Int private val expireAt K V gt Long private val onExpire K V gt Unit private val objects mutableMapOf lt K V gt private val expiringSlots until period map mutableMapOf lt K V gt toList private var expiringSlotIdx init vertx setPeriodic delay terminateExpiringSlot expiringSlotIdx if expiringSlotIdx gt period expiringSlotIdx fun getOrPut key K defaultValue gt V V return objects getOrPut key defaultValue invoke also expiringSlots expiringSlotIdx key it private fun terminateExpiringSlot val now System currentTimeMillis expiringSlots expiringSlotIdx apply forEach k v gt val expireAt expireAt k v when expireAt lt now gt objects remove k let onExpire k it else gt var shift expireAt now delay toInt if shift gt period shift period val nextExpiringSlotIdx expiringSlotIdx shift period expiringSlots nextExpiringSlotIdx k v clear data class Builder lt K V gt var delay Long var period Int var expireAt K V gt Long K V gt Long MAX VALUE var onExpire K V gt Unit K V gt fun delay delay Long apply this delay delay fun period period Int apply this period period fun expireAt expireAt K V gt Long apply this expireAt expireAt fun onExpire onExpire K V gt Unit apply this onExpire onExpire fun build vertx Vertx PeriodicallyExpiringHashMap vertx delay period expireAt onExpire Here are the benefits of this data structure Now we just have a bunch of time slots So instead of walking through all the objects in our map every expirationDelay we can walk trough a single slot So instead of checking on K objects every second we will check on K only We don t need to create a copy of original map every time we decide to walk though it In the previous example it also was an issue because rtpSteams filtervalues created a copy of the original map The last and the most important Our implementation will stay consistent within a particular verticle context That means you can simply extend it and implement the rest of the methods including tricky ones like size ConclusionsFinally let s see how our verticle will look like with the new PeriodicallyExpiringHashMap data structure class RtpStreamHandler AbstractVerticle var expirationDelay Long var aggregationTimeout Long private lateinit var rtpStreams PeriodicallyExpiringHashMap lt String RtpStream gt override fun start rtpStreams PeriodicallyExpiringHashMap Builder lt String RtpStream gt delay expirationDelay period aggregationTimeout expirationDelay toInt expireAt rtpStream gt rtpStream updatedAt aggregationTimeout onExpire rtpStream gt terminateRtpStream rtpStream build vertx vertx eventBus localConsumer lt RtpPacket gt on rtp packet event gt val rtpPacket event body handleRtpPacket rtpPacket fun handleRtpPacket rtpPacket RtpPacket val rtpStream rtpStreams getOrPut rtpPacket rtpStreamId RtpStream rtpStream addPacket rtpPacket fun terminateRtpStream rtpStream RtpStream vertx eventBus localSend on rtp stream rtpStream The code looks clean and simple And it s all due to the Vert x event loop thread model ‍Happy coding Your SIP team	2021-09-22 21:23:40
