Short Description
Contains 'ztsdb' and 'append' executables.
Full Description

ztsdb is a fast, small and lightweight multi-user noSQL column-store database management system designed and optimized for the update, storage and handling of time-series data. Its query and manipulation language is based on the R programming language and allows complex selections of data inside a time-series or across multiple time-series. It is licensed under GPLv3.

Using the image

Running a container

Run a container with bash:

docker run -it lsilvest/ztsdb bash

Starting ztsdb

In this shell, start an instance of ztsdb:


You can use the quit command to terminate the ztsdb instance at any time:


Running multiple instances

One can start multiple containers to test multiple instances or to simulate real-time append to time-series. To access an instance from outside the container, publish the listen port when running the container:

docker run -it -p 19300:19300 lsilvest/ztsdb bash

Make note of the IP address of the container; Here is one way of getting it:

ip addr show

In this example, we will assume the container's IP address is

In this shell, start a ztsdb instance listening on the published port:

ztsdb -p 19300

Connecting from another ztsdb instance

Other ztsdb instances can be started in the same way as above. Once the ztsdb has been started, a connection can be established as usual from the ztsdb command line:

c1 <- connection("", 19300)

Append utility

The append utility generates append messages for a time-series at a specified frequency:

usage: append <ip> <port> <rate> <varname[,name1,name2,...]> <ncols> [max-msgs]

To use it, a time-series must first be created on the ztsdb server instance:

data  <-  matrix(0, 0, 3, dimnames=list(NULL, c("a","b","c")))
idx   <-  as.time(NULL)
a     <<- zts(idx, data)

Then append can be started from another container like this (IP address=, port=19300, rate=100000 msg/second, time-series' name=a, number of columns=3, continue sending indefinitely):

append 19300 100000 a 3

More information on the append utility can be found here.
