chronicle-engine's Introduction

Chronicle Overview

Chronicle Software provides libraries to help with fast data. The majority of our customers are in financial services. Our products include:

Chronicle FIX/ITCH Engine - Low latency FIX/ITCH engine in Java for all versions of FIX. Can parse and generate messages within 1 microsecond.

Chronicle Microservices Framework - Microservices built with Chronicle Services are efficient, easy to build, test, and maintain. Equally importantly they provide exceptional high-throughput, low latency, and transparent HA/DR.

Chronicle Matching Engine - forms the backbone for a resilient and scalable exchange solution. It provides order matching, validation, and risk checks with high capacity and low latency. It has a modular and flexible design which enables it to be used stand-alone, or seamlessly integrated with Chronicle FIX and Chronicle Services.

Chronicle EFX - built on Chronicle Microservices, EFX contains components for Aggregation, Pricing, Hedging, Position Keeping, P&L, Market Gateway and Algo containers. EFX allows the customer to use off the shelf functionality built and maintained by Chronicle, or to extend and customise with their own algos and IP - the best compromise of "buy vs build".

Chronicle Queue and also Chronicle Queue Enterprise - using Chronicle Queue for low latency message passing provides an effectively unlimited buffer between producers and consumers and a complete audit trail of every message sent. Queue Enterprise provides even lower latencies and additional delivery semantics - for example - only process a message once it is guaranteed replicated to another host(s).

Chronicle Map is a key-value store sharing persisted memory between processes, either on the same server or across networks. CM is designed to store the data off-heap, which means it minimizes the heap usage and garbage collection allowing the data to be stored with sub-microsecond latency. CM is structured key-value store able to support exceptionally high updates and high throughput data e.g. OPRA Market Data with minimum configuration. Replication is provided by Chronicle Map Enterprise

chronicle-engine's Issues

Unable to build and test due to dependency on chronicle enterprise snapshots

Hello,

Is this repository dependent on artifacts that are only available in Chronicle enterprise repositories (snapshots & release)?
Is there a way to build this project using Open Source snapshots (on OSS sonatype)?

Currently I'm getting the following errors, even when checking out with the latest release tag (chronicle-engine-1.14.5):

Chronicle-Engine Demo not working

As a side note, I was having trouble getting the demo to work using tagged release of Chronicle-Engine 1.13.27 (we're using this version as we're just in the initial phases of experimentation so haven't got access to later versions via the private repository).

I'm running via IntelliJ with the classpath set to the chronicle-engine-demo module so it's picking up this engine.yaml.

DemoMapListener/DemoMapProducer can't connect to the Engine started by RunEngineMain, see the logging below from Listener:

WARN net.openhft.chronicle.network.connection.FatalFailureConnectionStrategy - unable to connected to localhost/127.0.0.1:8088 - localhost:8088, name=/

I was able to get this to work by re-adding the server config removed in this commit

My question is this: was it an accidental removal of that config or was this deliberate? If the latter is there some additional config that's not referred to in the demo docs?

NFS mounting is also not working in the demo unless you restore the dependency to chronicle-engine-nfs and re-add the NfsCfg.class removed from RunEngineMain and restore the NfsConfig into the demo engine.yaml.

Pointing to failed release version of chronicle-network

QueueEvents

Hi Peter Lawrey, i love chronicle queue and i dont have a way to catch add, update, delete events.

create index view documentation

Map ignores Key/Value types when created remotely

implement net.openhft.chronicle.engine.tree.ChronicleQueueView#unregisterSubscriber

ArrayMapTest is hanging with Text wire (textwire disabled for now)

works perfectly fine with Binary

Upgrade Engine to Map3

map3 may have to support net.openhft.chronicle.wire.Marshallable
remove replication of map and queue from engine.
add support for updated events for keys in Map 3

Fixed net.openhft.chronicle.engine.queue.QueueAsMapViewTest

see http://teamcity.higherfrequencytrading.com:8111/viewLog.html?buildId=255733&tab=buildResultsDiv&buildTypeId=OpenHFT_ChronicleEngine_Snapshot

Replication tests not shutting down cleanly

Replication3WayIntIntTest leaves a RCEventHnalder still running after shutdown.

JDK 9 support

The project currently fails on JDK 9:

java.lang.NoSuchMethodError: sun.nio.ch.DirectBuffer.cleaner()Lsun/misc/Cleaner;

To reproduce:

   @Test
    public void testMapEvents() throws Exception {
        net.openhft.chronicle.bytes.NativeBytesStore.elasticByteBuffer(256, 1024);
    }

If a more elaborate test is required you can checkout ChronicleEngineConsumerTest.

Thanks!

Add a MapView for Chronicle Queue

The MapView would have a key and an index to the queue entry.

Add the option to migrate values after a roll. e.g. after a cycle roll, migrate all keys older than a cycle (the one before the previous cycle)

View subscriptions can fire spurious events.

A queue contains events of TYPE_A and TYPE_B, published by one or more publishers
A subscriber, SUB_1, subscribes to events of TYPE_A from the queue
SUB_1 receives the initial snapshot of TYPE_A events
A publisher writes an event of TYPE_B to the queue
SUB_1 receives a TYPE_A event notification

Open source version slow on purpose?

Your chart is interesting, normally enterprise means extra features, etc, however performance should be the same, how is it that its 10 times slower.
Hazelcast and others offer the same framework and charge for support and enterprise specific features... same with gridgain
thanks

Error in the logs "Checksum validation failed, expected <!DOCTYPE but is "

http://stackoverflow.com/questions/13077351/nexus-maven-domain-suffix-incorrect

Add Chronicle-Websocket-Jetty integration for Chronicle Engine.

Support access to queues and maps via web sockets, with a sample program in Java Websockets and JavaScript.

This will help demonstrate Engine as an API Gateway http://microservices.io/patterns/apigateway.html

e.g.

attach to an asset via URL
publish messages and enable subscriptions via JSON commands.

Later I would like to be able to bind to an actor/value in a map or queue and issue method calls.

Provide a possibility to override wrapping rules for Asset Tree

AssetTree Interface question

I've been taking a look at Chronicle-Engine - in particular the QueueView - and noticed something I just wanted to double check.

The following two default methods are declared - they are completely identical except for the ordering of the variables. Is there any particular reason for this?

    @NotNull
    default <T, M> QueueView<T, M> acquireQueue(@NotNull String uri, Class<T> typeClass, Class<M>
            messageClass, final String cluster, String basePath) {

        @NotNull final RequestContext requestContext = requestContext(uri).basePath(basePath);

        if (requestContext.bootstrap() != null)
            throw new UnsupportedOperationException("Its not possible to set the bootstrap when " +
                    "acquiring a queue");

        return acquireView(requestContext.view("queue").type(typeClass).type2(messageClass)
                .cluster(cluster));
    }

    @NotNull
    default <T, M> QueueView<T, M> acquireQueue(@NotNull String uri, String basePath, Class<T> typeClass,
                                                Class<M> messageClass, final String cluster) {

        @NotNull final RequestContext requestContext = requestContext(uri).basePath(basePath);

        if (requestContext.bootstrap() != null)
            throw new UnsupportedOperationException("Its not possible to set the bootstrap when " +
                    "acquiring a queue");

        return acquireView(requestContext.view("queue").type(typeClass).type2(messageClass)
                .cluster(cluster));
    }

fixed issue with procPrefix in network stats

We are having some issue with the creation of proc files by chronicle engine. Specifically, we have been using the method

VanillaAssetTree createAssetTree(String yamlConfigFile, String region, int hostId, String clusterName, String procPrefix)

in EngineInstance to create chronicle maps. We use the procPrefix parameter so that the additional queues created by chronicle engine are in a path of our choice. This is necessary as we are not allowed to create files in the process’s working directory in prod, which is monitored.

In particular, we need to control where the following directory is created:
proc\connections\cluster\throughput
This directory, in turn, contains a subdirectory for each node in the cluster.

The procPrefix parameter has effect when I run locally with a 3 node cluster configuration, but when the same process runs on a server, the queues for the local host id are created in the current working directory, while the queues for the other nodes are created where specified by the proc prefix parameter.
That is, if the process runs as with host id = 1:
· proc\connections\cluster\throughput\2 and proc\connections\cluster\throughput\3 -> created in procPrefix directory, as expected;
· proc\connections\cluster\throughput\1 -> created in current working directory, wrongly.

Looking at the code for chronicle engine, and searching for “\proc\connections\cluster\throughput” it seems that there are classes that reference the path without the prefix parameter. For example AssetTree class, or EngineNetworkStatsListener class.
