librdx

brix SST CLI tool

brix allows for basic manipulations with .brik file stacks. .brik files are RDX SSTs, i.e. tables of RDX objects sorted by id. brix compares to an LSM database like a wrench compares to a workshop.

Opening a stack

brix open opens a BRIX file, including its stack of dependencies (a version). One can refer to a version by its hash, hash prefix or the file path (which contains the hash).

• brix open 8469d149546328e3f8bde5ec179f617d1bfa740f3b44c80f3f6617896cc9b1b6
• brix open 8469d14
• brix open ./.rdx/8469d149546328e3f8bde5ec179f617d1bfa740f3b44c80f3f6617896cc9b1b6.brik

Blending additional .brik files

brix add adds an SST file to the stack, including its (missing) dependencies. Any queries would reflect the added data.

• brix add c256798798d1a247bebfb833f709f2f1e23c365c88015c421dff9ec426f9517e
• brix add ./.rdx/c256798798d1a247bebfb833f709f2f1e23c365c88015c421dff9ec426f9517e.brik
• brix add c2567987

Reading entries

brix get queries the particular record by its ID

• brix get b0b-123

RDX objects may include other objects by reference, e.g. {@Bob-outer key:"value" referTo:[@B0b-inner]}

brix reget queries records recursively, thus building a full document (tree)

• brix reget b0b-123

Merging files, compacting stacks

Many database operations boil down to .brik file merges. Those are compactions, branch merges, patching and so on. brix merge merges some topmost files producing one new SST file. The resulting version hash is printed.

• brix merge merges some reasonable number of files roughly to maintain 8:1 size ratio,
• brix merge 4 a way to specify the number of files to merge,
• brix merge c25679879 merge files on top of this one.

Generating standalone patches

brix patch converts an RDX document to a temporary SST file and adds it to the stack. That should be an RDX document with full metadata as BRIX only stores data and merges the changes. There is no diffing of the document to the existing state. Applying standalone patches can be done with brik add.

Syncing to other repos

brix pull downloads the specified .brik file from a remote repo, including its dependencies, e.g.

brix pull http://repo.dev/brix/c2567987

brix push uploads a file and its dependencies

brix pull http://repo.dev/brix/9afbc90e
