Welcome to Brim Cloud!
We've spent the past few years building the open-source Zed project and are now building a cloud service to provide an easy-to-use Zed lake.
Let us know if you would like to be a pre-alpha tester, free of charge. You will be helping us build out our cloud product and your participation will be greatly appreciated. To sign up for the pre-alpha test, please email us at cloud-alpha@brimdata.io and we'll get the conversation going.
When you sign up, you will provide us your preferred email and we will enable your access via auth0. You will get a standard account registration email from auth0 to establish your account.
We will provide a custom DNS name pointing to a dedicated EC2 instance to sign into the service via your auth0 credentials from one of our clients.
Your Zed data will be stored in one of our S3 buckets, which we can make
available to you for direct migration or backup. You can copy all of the lake data
to your own domain (e.g., your own S3 bucket or local filesystem) and run your
own instance of zed serve to precisely recreate the lake from
the Brim Cloud.
You can access your Zed lake in the Brim cloud using
- from your desktop using the Brim app
- from the command-line using
zedCLI command - from your Python using our Python client
For the configuration options below, we will assume the host name we provided
you at signup is <custom>.lake.brimdata.io. You should replace
<custom> with the DNS name we assigned you.
When you first connect, there will be a test pool set up for you called "Welcome" with some sample Zed data.
The Brim App can communicate with and switch between different instances
of Zed lakes, including the local Zed lake it automatically launches
on localhost. Lake connections are a bit like Slack teams, where Slack
lets you easily switch between teams.
To connect to the cloud from the Brim app, click on the lake dropdown
in the upper left area of the window where you see the down carrot
and click on Add Lake.... Once the cloud connection has been created,
you can use this dropdown to switch between your local lake and the cloud
(as well as other cloud lakes or lakes that you set up on your own server
with zed serve).
Under the Name input, provide a name for the lake connection that you would like to
appear in listing of available lakes. Under the Host input, provide the URL
of the lake service, in this case, https://<custom>.lake.brimdata.io
You can import some sample queries relevant to the Welcome pools
into the app's query library by
downloading queries.json.
You can simply drag this file onto the Queries panel in the Brim app
and this will add a query folder called "Welcome".
You may also import this file by clicking on the + button
in the Queries panel and selecting Import from JSON.
The zed command lets you access all of the functionality exposed to the Brim
App on the command line. Type zed -h to get online help.
The quickest way to get the zed command on macOS, Linux, or Windows is to download
a pre-built release.
To use the Brim cloud with zed, you can use the -lake command-line option
but for all the examples here, we will use presume you set the
following environment variable to point at your cloud instance:
export ZED_LAKE=https://<custom>.lake.brimdata.io
Note that the service is available on the default SSL port rather than the
zed servedefault port of 9867.
Authenticate your lake connection using zed auth login:
zed auth login
This will launch your browser with an authentication dialogue pointing
at the auth0 service for Brim and command will print a confirmation code
on the terminal. Once you confirm in the auth0 web dialogue, zed auth login
will report success and you will be logged in.
Note that zed auth login will store your access credentials in $HOME/.zed/credentials.json.
Once authenticated, check that the service is working
by running a query command on your "welcome" data:
zed query "from Welcome"
Note that you can delete the
Welcomepool at any time. It is just here to help you get started. You can always reproduce it by creating the pool and copying the data from this repo and optionally dragging the Welcome queries into your app's query library.
To access your lake via the Python client, first authenticate as described
above using zed auth login as the Python client requires access to your login
credentials stored in $HOME/.zed/credentials.json.
If you haven't installed the Python zed module, run
pip3 install "git+https://github.com/brimdata/zed#subdirectory=python/zed"
Run a test by creating a pool, loading data from Python, and reading it back:
import zed
import os
c = zed.Client(os.environ.get('ZED_LAKE'))
c.create_pool('test')
c.load('test', '{a:1}{a:2}{a:3}')
for v in c.query('from test'):
print(v)
If you do many small loads, the queries will run slow because the current lake implementation does not yet implement the planned design. See issue 2936.
Compaction is coming soon.
If you pull very large result sets down into the Python client, the network
transfer using ZJSON will run much slower than ZNG. (We plan to add native
ZNG support to the Python client but it's not yet implemented.) If you want
to retrieve large data sets from your Zed lake it's best to use zed query,
which defaults to the ZNG format (unless you send the output to a terminal,
in which case the textual ZSON format is default).
If you run into problems or have questions, please reach out to us on our public Slack channel.
