Usage

Note: Karai aims to always compile and run on Linux targetting the AMD64 CPU architecture. Other operating systems and architectures may compile and run this software but should do so expecting some inconsistencies.

Launch Karai Coordinator

make postgres

make migrate

make karai

Deprecated> For optimal transaction speed as coordinator:

Deprecated> When skipping the write process, you are taking some risk if Karai crashes before you write transactions to disk. You can write your transactions to disk with the wt command.

./go-karai -coordinator -write=false

To place graph objects in a different directory:

./go-karai -coordinator -graphDir="/literal/path/to/graph/"

Operating System

Karai supports Linux on AMD64 architecture, but may compile in other settings. Differences between Linux and non-Linux installs should be expected.

Optional: Compile with all errors displayed, then run binary. Avoids "too many errors" from hiding error info.

go build -gcflags="-e" && ./go-karai
