Git-like versioning tools for Datahike.

branch! clj

(branch! conn from new-branch)

Create a new branch from commit-id or existing branch as new-branch.

branch-as-db clj

(branch-as-db store branch)

Loads the database stored at this branch.

branch-history clj

(branch-history conn)

Returns a go-channel with the commit history of the branch of the connection in form of all stored db values. Performs backtracking and returns dbs in order.

commit-as-db clj

(commit-as-db store commit-id)

Loads the database stored at this commit id.

commit-id clj

(commit-id db)

Retrieve the commit-id for this db.

delete-branch! clj

(delete-branch! conn branch)

Removes this branch from set of known branches. The branch will still be accessible until the next gc. Remote readers need to release their connections.

force-branch! clj

(force-branch! db branch parents)

Force the branch to point to the provided db value. Branch will be created if it does not exist. Parents need to point to a set of branches or commits.

Be careful with this command as you can render a db inaccessible by corrupting a branch. You will also conflict with existing connections to the branch so make sure to close them before forcing the branch.

merge! clj

(merge! conn parents tx-data)

(merge! conn parents tx-data tx-meta)

Create a merge commit to the current branch of this connection for parent commit uuids. It is the responsibility of the caller to make sure that tx-data contains the data to be merged into the branch from the parents. This function ensures that the parent commits are properly tracked.

parent-commit-ids clj

(parent-commit-ids db)

Retrieve parent commit ids from db.
