cdb
This is a Go package to read and write cdb ("constant database") files.
The cdb file format is a machine-independent format with the following features:
- Fast lookups: A successful lookup in a large database normally takes just two disk accesses. An unsuccessful lookup takes only one.
- Low overhead: A database uses 2048 bytes, plus 24 bytes per record, plus the space for keys and data.
- No random limits: cdb can handle any database up to 4 gigabytes. There are no other restrictions; records don't even have to fit into memory.
See the original cdb specification and C implementation by D. J. Bernstein at http://cr.yp.to/cdb.html.
Installation
Assuming you have a working Go environment, installation is simply:
go get github.com/jbarham/cdb
The package documentation can be viewed online at https://pkg.go.dev/github.com/jbarham/cdb or on the command line by running go doc github.com/jbarham/cdb.
The included self-test program cdb_test.go illustrates usage of the package.
Utilities
The cdb package includes ports of the programs cdbdump and cdbmake from the original implementation.
