Basic tick system

This is a basic tick system with fake feed, tickerplant, rdb+ hdb and a gateway to query data.

Mutliple rdbs/hdbs can be spawned and will connect and subscribe and be able to be queried.

There is no data persistance, however hdb data can be generated using the createHdb.q script.

Building under qp

Download the qpacker-examples.tgz package via Nexus:

To build each of the containers run

tar -xvzf qpacker-examples.tgz
cd qpacker-examples/basic-tick-system
qp build

Running under docker-compose

After building you can run under docker-compose as follows

docker-compose up

Repo structure

cfg - Configuration directory

  • Contains schema and process configuration

src/lib - Libraries dir

  • Contains code that multiple processes share

src/processes - process files

Gateway usage

By default the gateway is on 5050 if booted through bootSystem.q.

Can query via queryData[table;syms] on the gw that will dispatch to a random rdb and hdb.

The table flowing through the system is example. To connect to the gw and query for all syms:

gw:hopen 5050;


The repo contains a library funcDownHandle.q that contains a function for the gw that will send a function down a handle tto rdb/hdbs.

For this to work, this library must remain uncompiled. This lib is here to verify that the build can identify which libs to not compile
