MarshalLogMessage serializes the log message and prepends additional encoding
information to each message. Currently, we prepend three bytes to each log
message:
byte[0]: encodeVersion - this is currently a constant within the code. If we
modify structs such that they encode differently, we'll have to change the
constant and keep previous versions of structs for deserialization.
byte[1]: encodeType (e.g. "json", etc.)
byte[2]: logMessageType
If we get into a situation where we want more flexibility in these message
header bytes—for example, if we want to use more than three bytes—we could do
something with the first bit of the encodeVersion: if it's 1, that could
indicate that there are additional header bytes, and the following seven bits
could indicate how many.

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.
