* implemented distinct
* implemented distinct
* uses first cut of a buffer pool, and extendible hashing with thresholded spill to disk
* tests
* cleaned up some stuff around query plan output to make developing tooling easier
* added optimization to call PQL Distinct()
* fixed test
* fix for passing wrong index name in orchestrator
* back out change to DistinctTimestamp
* fix other instance of wrong table name being passed
* use full index name instead of abbreviated one for translation. sigh.
* removed some unused code

DAX
DAX encapsulates anything which covers all of the services which make up the "disaggregation of storage and compute" project. Initially, this will include integration tests which pull in things like Metadata Services (MDS), including the Controller, as well as FeatureBase and IDK-based ingesters.
Setting up the tests
The DAX test currently requires docker images for: featurebase and datagen.
If at any point you run into problems with go mod failing to reference a private
repo, make sure that you have gitlab.com/molecula in your GOPRIVATE
environment variable.
Note that during the docker image build step, go mod vendor is run, which
creates a vendor directory in the root directory, and copies that to docker
during the build stage. Just be aware of this; you may want to remove that
vendor directory after you're done building docker images.
Possible Configuruation
The following were relevent when the dax code was in a separate repository. These may no longer be relevant.
I needed to but this in my ~/.profile file:
export GOPRIVATE=github.com/molecula,gitlab.com/molecula
And this in my ~/.gitconfig
[url "ssh://git@github.com/"]
insteadOf = https://github.com/
[url "ssh://git@gitlab.com/"]
insteadOf = https://gitlab.com/
Then make docker ran successfully.
Build the FeatureBase docker image
- Check out the dax branch of the featurebase repository.
- Run
make docker-image-featurebaseto build the docker image - You should now have an image in docker named
dax/featurebasewith the taglatest.
Build the Datagen docker image
cd <featurebase_repo_root>/idk- Run
make docker-image-datagento build the docker image - You should now have an image in docker named
dax/datagenwith the taglatest.
Running the tests
- Check out the dax branch of the featurebase repository.
- Change into the
daxdirectory:cd dax - Run
make test-integration.
