mdb_load - LMDB environment import tool
] [-f file]
utility reads from the standard input and loads it into the
LMDB environment envpath
The input to mdb_load
must be in the output format specified by the
(1) utility or as specified by the -T
- Write the library version number to the standard output, and exit.
- -f file
- Read from the specified file instead of from the standard input.
- Load an LMDB database which does not use subdirectories.
- -s subdb
- Load a specific subdatabase. If no database is specified, data is loaded
into the main database.
- Don't overwrite existing records when loading into an already existing
database; just skip them.
- Load data from simple text files. The input must be paired lines of text,
where the first line of the pair is the key item, and the second line of
the pair is its corresponding data item.
A simple escape mechanism, where newline and backslash (\) characters are
special, is applied to the text input. Newline characters are interpreted
as record separators. Backslash characters in the text will be interpreted
in one of two ways: If the backslash character precedes another backslash
character, the pair will be interpreted as a literal backslash. If the
backslash character precedes any other character, the two characters
following the backslash will be interpreted as a hexadecimal specification
of a single character; for example, \0a is a newline character in the
ASCII character set.
For this reason, any backslash or newline characters that naturally occur in
the text input must be escaped to avoid misinterpretation by
Exit status is zero if no errors occur. Errors result in a non-zero exit status
and a diagnostic message being written to standard error.
