Fetch known network config #1156

ch1bo · 2023-11-07T11:59:05Z

📡 Fetch known network configuration in hydra-cluster instead of using the vendored config from cardano-configurations
📡 Remove known network configurations from hydra-cluster
📡 Re-add the submodule to cardano-configuration, but only use it for the testnets/ scripts
📡 Clean up nix invocations in CI and documentation which were still mentioning ?submodules=1

CHANGELOG updated or not needed
Documentation updated or not needed
Haddocks updated or not needed
No new TODOs introduced or explained herafter

Instead of including configuration files for various known networks, the withCardanoNodeOnKnownNetwork function now fetches the files from a known remote server.

This is now possible as submodules were only problematic when mentioned in .cabal files.

This is not needed since we removed the need for submodules from the haskell package builds.

Transactions Costs

Sizes and execution budgets for Hydra protocol transactions. Note that unlisted parameters are currently using arbitrary values and results are not fully deterministic and comparable to previous runs.

The minting policy hash is only usable for comparison. As the script is parameterized, the actual script is unique per Head.

End-To-End Benchmark Results

This page is intended to collect the latest end-to-end benchmarks results produced by Hydra's Continuous Integration system from the latest master code.

Please take those results with a grain of salt as they are currently produced from very limited cloud VMs and not controlled hardware. Instead of focusing on the absolute results, the emphasis should be on relative results, eg. how the timings for a scenario evolve as the code changes.

3-nodes Scenario

A rather typical setup, with 3 nodes forming a Hydra head.

Number of nodes	3
Number of txs	900
Avg. Confirmation Time (ms)	71.437442543
P99	220.30838848999997ms
P95	156.33363704999996ms
P50	56.697935ms
Number of Invalid txs	0

Baseline Scenario

This scenario represents a minimal case and as such is a good baseline against which to assess the overhead introduced by more complex setups. There is a single hydra-node d with a single client submitting single input and single output transactions with a constant UTxO set of 1.

Number of nodes	1
Number of txs	300

I like we are now fetching configurations from remote URL, but then why adding back submodules for testnets? Can't we just do the same, pull the configuration from cardano-world?

Was not in the mood of doing shell scripting. Maybe I do it in a separate PR?
