2-minute intro video front screen has typo

The intro video you get when you first connect to mldb Community edition says "Notebook Interfacd".
I know - really minor bug - but first impressions are important!

Simple UI to store credentials

MLDB can store credentials to facilitate access to data behind various protocols requiring authentication.

The ui, a fork of Jupyter Notebooks, should have a new tab to manage credentials.

Context

Files and URLs
Jupyter Notebook

TODO

A new tab into MLDB's Jupyter Notebook that allows to:
- List existing credentials (protocol + username, NOT passwords)
- Create credentials
- Update existing credentials
- Delete existing credentials

Have MLDB compile under MacOSX

Blog post about MLDB Hacktoberfest 2016

Compile MLDB under MacOSX. Alter the code if needed, but it must not break existing compatibilities.
If special instructions need to be followed (eg.: setup, package installations), provide an instruction page.

Proper error message for invalid "SELECT col AS * FROM ds" query

Blog post about MLDB Hacktoberfest 2016

Running the query

SELECT col AS * FROM ds

is illegal. It currently returns a non useful message with a status code 500 (server error). It should instead return a useful message with a status code 400 (client error).

Task

Mldb1788SelectColAsStarErr test must pass without "expectedFailure".

Community edition is asking for license key

From the documentation, "The MLDB Community Edition is a distribution of MLDB that can be built entirely from open-source software. The license is the Apache License v2.0...". This leads me to think that no license key is required to run the Community Edition.

By contrast, "The MLDB Enterprise Edition is a pre-built binary distribution of MLDB which includes the same software as the Community Edition plus the closed-source MLDB Pro Plugin. It is available under two license options: ...". Both license options require license keys.

I have built the Community Edition. When I connect to it, I get a screen asking for a license key.

any benchmarks against mysql / redis / rocksdb etc?

just curious, any benchmarks for disk space size used, memory used, and processing time compared with some popular databases?

what differentiates mldb from the other mainstream dbs?

libpq missing from mldb build

Building the Community edition of mldb, at the "make compile" step, I got the following error:

  core/kernels/reader_base.pb_text.cc
  ./mldb/postgresql/postgresql_plugin.cc:14:33: fatal error: postgresql/libpq-fe.h: No such file or directory
   #include <postgresql/libpq-fe.h>
                                   ^
  compilation terminated.

I was able to work around the issue by doing:

$ apt-get install libpq-dev

The rest of the build worked fine. However, when I ran the mldb docker container, I got the following errors:

MLDB (version 2016.11.03.dev-1f737de) is starting up
MldbServer [2016-11-03T14:49:27.077+00:00] error error loading plugin file:///opt/mldb/plugins/postgresql/: couldn't find plugin library '/opt/mldb/plugins/postgresql/lib/libmldb_postgresql_plugin.so': libpq.so.5: cannot open shared object file: No such file or directory

I built the mldb docker object after first building the Community versions of baseimage and mldb_base.

For reference, when I built the mldb docker object using the Enterprise versions of baseimage and mldb_base, there were no runtime errors.

I'm using Ubuntu 14.04.

Pip version in the latest release too low

Hello, dear developers. I have tried to build MLDB according to Building.md inside the master branch, using the toolchain of gcc. However, when I began to run commands of "make", many errors occurred.

I firstly tried to fix the errors by modifying the files according to the error logs, however, I was finally stuck at the cffi installation error:

Running setup.py install for cffi ... error
...
c/call_python.c:6:56: error: dereferencing pointer to incomplete type ‘PyInterpreterState’ {aka ‘struct _is’} 
6 |   PyObject *m, *modules = PyThreadState_GET()->interp->modules;"

I thought I shoud blame the cPython or other modules, and reinstall them by myself, but the Makefile would reinstall all needed modules, referring from the build logs.

Then the notification down the error indicate reminded me:

You are using pip version 8.0.2, however version 21.3.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

Since the make process would set up a virtual environment and overwrite my 21.3.1 installation inside contemporary virtual environment, I find the Makefile sentences for the assigned pip version 8.0.2 and change them to 21.3.1, which is the latest version of pip till this Issue. Then though the environment was rebuilt, all prevoius errors disappeared!!! Though I am still pacing the following building steps, I think this problem could be perfectly fixed by simply upgrading the pip version.

Back to the master branch, the commits are mainly in-pace with the pip upgrading, but the release_latest branch recommended by the Building.md has not received the update. Could you please upgrade the pip version inside the build files of release_latest branch? Or could you please find other solutions? That would help a great deal to freshmen like me, thanks!

Reason to use / checkout mldb.ai in 2022?

I got interested in the project after looking into the documentation. It seems the project is mostly abandoned - not only by companies, but also by volunteer. Is there any reason to still look into the system? What would be alternatives nowadays?

Demo: Music recommendation demo using the Million Song Dataset

Blog post about MLDB Hacktoberfest 2016

DOD: Create demo in the form of a Jupyter notebook showing how to solve Kaggle's Million Song Dataset Challenge. The demo should follow the standard pattern. Example demos are available here: https://docs.mldb.ai/doc/#builtin/Demos.md.html

Is mldb a full-featured end-to-end system?

Because of the "database" in the name, I first thought that mldb is something like a feature store. After reading a bit more it seems to me, that - instead - it is a full out-of-the-box, batteries-included type of system, where I am supposed to use the provided ML implementations (even though I can write plug-ins for the system). Which impression is correct?

My current understand is this: I use the mldb-SQL queries to define a DAG (directed acyclic graph) of data processing (including ML), the input data and the output REST ports. Is this right?

Add missing model evaluation metrics

Blog post about MLDB Hacktoberfest 2016

Rationale: Many Kaggle competitions use evaluation metrics that are currently not reported by MLDB. This makes it harder to use to solve competitions.

DOD: Add the following metrics to classifier evaluation:

Regression
- Mean absolute error: https://www.kaggle.com/wiki/MeanAbsoluteError
Binary classification
- Log loss: https://www.kaggle.com/wiki/LogarithmicLoss
Multi-class classification
- Log loss: https://www.kaggle.com/wiki/MultiClassLogLoss
- Hamming Loss: https://www.kaggle.com/wiki/HammingLoss

They should be added in: https://github.com/mldbai/mldb/blob/master/plugins/accuracy.cc

Internal ticket: MLDB-1968

is this project still alive?

the last commit was in oct 2018, is this still active and working?

merged dataset should accept a list of strings

Blog post about MLDB Hacktoberfest 2016

To create a merged dataset, one must specify the dataset with objects containing the "id" key. Eg.:

{
    'type' : 'merged',
    'params' : {
        'datasets' : [{'id' : 'ds1'}, {'id', 'ds2'}]
    }
}

If would be convenient if the ids would also work directly. Eg.:

{
    'type' : 'merged',
    'params' : {
        'datasets' : ['ds1', 'ds2']
    }
}

Context

merge dataset

Task

Mldb1921MergeDsStrings test must pass without "expectedFailure".

Compile errors

Hi,

I'm getting a lot of compile errors. Not sure if i'm doing something wrong or if the source code is bad. Could anyone please advise on how to proceed forward with building the community edition ? :

Horizontal aggregators without FROM clause should work

Blog post about MLDB Hacktoberfest 2016

A query using an horizontal aggregator but no dataset should work. Eg.:

SELECT horizontal_sum({1 AS a, 2 AS b})

should return 3. Currently it fails as an invalid query.

Context

Aggregate Function (See Vertical, Horizontal and Temporal Aggregation)

Task

Mldb1911HorizontalAggNoFrom test must pass without "expectedFailure".
Add the missing horizontal aggregators to the test to cover them all.

Build failures

hey guys, I've tried twice now and failed to build this project both times despite following the instructions.

I'll be using VM's so I can build whatever environment I need, what OS do you guys use to build this? Debian, Ubuntu, etc?

Remove unnecessary null pointer checks

An extra null pointer check is not needed like in the destructor for the class “QuadtreeNode”.

Demo: Create demo using Twitter data and NLP techniques

Blog post about MLDB Hacktoberfest 2016

DOD: Create demo in the form of a Jupyter notebook using Twitter data and NLP techniques. The demo should follow the standard pattern. Example demos are available here: https://docs.mldb.ai/doc/#builtin/Demos.md.html

The demo should use a publicly available Twitter dataset. It can then show how to generate insights from the data using unsupervised techniques (clustering, visualisation, topic extraction, etc) or show how it can be used to train a supervised model.

This is an example of a demo importing text and making a visualisation from it: https://docs.mldb.ai/ipy/notebooks/_demos/_latest/Mapping%20Election%20Press%20Releases.html

Docker not working in macOS / OSX

Hi guys, I've been trying to get the MLDB running on my local using docker from quay.io/datacratic/mldb:latest

However, I've been facing with the following error:

Aborting boot: directory mapped to /mldb_data owned by root

FYI, I've created a new user called mldb (non-root) and change command to id mldb to use the non-root user, however it still returns the same error.

Any help would be appreciated.

OS: macOS 10.12.1
Docker: 1.12.3-beta30
