NAME
cdb —
constant database
DESCRIPTION
A cdb contains a data set as key/value
pairs, and multiple values can be associated with the same key. In such
case, multiple queries should be done to retrieve all the values for a given
key.
Because of how records are stored, the database size MUST be kept under 4 gigabytes.
ENCODED RECORD
cdb are created from encoded records, one
per line. The end of the data set is marked with an extra newline.
A record is encoded as
+klen,dlen:key->data
key and data are plaintext strings. klen is the number of bytes in key, while dlen is the number of bytes in data.
EXAMPLE
Encoded record format, suitable for creating a new
cdb
+3,5:one->Hello +3,7:two->Goodbye
