ClickHaskell

ClickHaskell is a set of Haskell libraries which allows
you to build integrations with ClickHouse DBMS

ClickHaskell aims to be balanced between
lightweightness, composability and simplicity

Design factors

ClickHouse stores data in a tables
ClickHouse has HTTP interface for accessing and manipulating tables states
HTTP request message-body to a DBMS server consists of a statement
There are a few formats that defines data serialization in statement
ClickHaskell should cover only problems related to communication protocol of ClickHouse DBMS
ClickHaskell should provide safe API that will help the end user think less about ClickHouse interface

We are using Nix flakes to set up whole development environment.

When you have configured Nix. Enter into nix shell and then run:

nix run

Nix will setup a database with development required schemas for you.

After dev-database Health status is Ready, you can start to work with database dependent code parts.

nix run .#profiling

will start profiling process.

You should see profiler.eventlog.html in the project
directory after the profiling process has completed successfully
