/** @page starting Getting Started
|
||||
|
||||
LMDB is compact, fast, powerful, and robust and implements a simplified
|
||||
variant of the BerkeleyDB (BDB) API. (BDB is also very powerful, and verbosely
|
||||
documented in its own right.) After reading this page, the main
|
||||
\ref mdb documentation should make sense. Thanks to Bert Hubert
|
||||
for creating the
|
||||
<a href="https://github.com/ahupowerdns/ahutils/blob/master/lmdb-semantics.md">
|
||||
initial version</a> of this writeup.
|
||||
|
||||
Everything starts with an environment, created by #mdb_env_create().
|
||||
Once created, this environment must also be opened with #mdb_env_open().
|
||||
|
||||
#mdb_env_open() gets passed a name which is interpreted as a directory
|
||||
path. Note that this directory must exist already, it is not created
|
||||
for you. Within that directory, a lock file and a storage file will be
|
||||
generated. If you don't want to use a directory, you can pass the
|
||||
#MDB_NOSUBDIR option, in which case the path you provided is used
|
||||
directly as the data file, and another file with a "-lock" suffix
|
||||
added will be used for the lock file.
|
||||
|
||||
Once the environment is open, a transaction can be created within it
|
||||
using #mdb_txn_begin(). Transactions may be read-write or read-only,
|
||||
and read-write transactions may be nested. A transaction must only
|
||||
be used by one thread at a time. Transactions are always required,
|
||||
even for read-only access. The transaction provides a consistent
|
||||
view of the data.
|
||||
|
||||
Once a transaction has been created, a database can be opened within it
|
||||
using #mdb_dbi_open(). If only one database will ever be used in the
|
||||
environment, a NULL can be passed as the database name. For named
|
||||
databases, the #MDB_CREATE flag must be used to create the database
|
||||
if it doesn't already exist. Also, #mdb_env_set_maxdbs() must be
|
||||
called after #mdb_env_create() and before #mdb_env_open() to set the
|
||||
maximum number of named databases you want to support.
|
||||
|
||||
Note: a single transaction can open multiple databases. Generally
|
||||
databases should only be opened once, by the first transaction in
|
||||
the process. After the first transaction completes, the database
|
||||
handles can freely be used by all subsequent transactions.
|
||||
|
||||
Within a transaction, #mdb_get() and #mdb_put() can store single
|
||||
key/value pairs if that is all you need to do (but see \ref Cursors
|
||||
below if you want to do more).
|
||||
|
||||
A key/value pair is expressed as two #MDB_val structures. This struct
|
||||
has two fields, \c mv_size and \c mv_data. The data is a \c void pointer to
|
||||
an array of \c mv_size bytes.
|
||||
|
||||
Because LMDB is very efficient (and usually zero-copy), the data returned
|
||||
in an #MDB_val structure may be memory-mapped straight from disk. In
|
||||
other words <b>look but do not touch</b> (or free() for that matter).
|
||||
Once a transaction is closed, the values can no longer be used, so
|
||||
make a copy if you need to keep them after that.
|
||||
|
||||
@section Cursors Cursors
|
||||
|
||||
To do more powerful things, we must use a cursor.
|
||||
|
||||
Within the transaction, a cursor can be created with #mdb_cursor_open().
|
||||
With this cursor we can store/retrieve/delete (multiple) values using
|
||||
#mdb_cursor_get(), #mdb_cursor_put(), and #mdb_cursor_del().
|
||||
|
||||
#mdb_cursor_get() positions itself depending on the cursor operation
|
||||
requested, and for some operations, on the supplied key. For example,
|
||||
to list all key/value pairs in a database, use operation #MDB_FIRST for
|
||||
the first call to #mdb_cursor_get(), and #MDB_NEXT on subsequent calls,
|
||||
until the end is hit.
|
||||
|
||||
To retrieve all keys starting from a specified key value, use #MDB_SET.
|
||||
For more cursor operations, see the \ref mdb docs.
|
||||
|
||||
When using #mdb_cursor_put(), either the function will position the
|
||||
cursor for you based on the \b key, or you can use operation
|
||||
#MDB_CURRENT to use the current position of the cursor. Note that
|
||||
\b key must then match the current position's key.
|
||||
|
||||
@subsection summary Summarizing the Opening
|
||||
|
||||
So we have a cursor in a transaction which opened a database in an
|
||||
environment which is opened from a filesystem after it was
|
||||
separately created.
|
||||
|
||||
Or, we create an environment, open it from a filesystem, create a
|
||||
transaction within it, open a database within that transaction,
|
||||
and create a cursor within all of the above.
|
||||
|
||||
Got it?
|
||||
|
||||
@section thrproc Threads and Processes
|
||||
|
||||
LMDB uses POSIX locks on files, and these locks have issues if one
|
||||
process opens a file multiple times. Because of this, do not
|
||||
#mdb_env_open() a file multiple times from a single process. Instead,
|
||||
share the LMDB environment that has opened the file across all threads.
|
||||
Otherwise, if a single process opens the same environment multiple times,
|
||||
closing it once will remove all the locks held on it, and the other
|
||||
instances will be vulnerable to corruption from other processes.
|
||||
|
||||
Also note that a transaction is tied to one thread by default using
|
||||
Thread Local Storage. If you want to pass read-only transactions across
|
||||
threads, you can use the #MDB_NOTLS option on the environment.
|
||||
|
||||
@section txns Transactions, Rollbacks, etc.
|
||||
|
||||
To actually get anything done, a transaction must be committed using
|
||||
#mdb_txn_commit(). Alternatively, all of a transaction's operations
|
||||
can be discarded using #mdb_txn_abort(). In a read-only transaction,
|
||||
any cursors will \b not automatically be freed. In a read-write
|
||||
transaction, all cursors will be freed and must not be used again.
|
||||
|
||||
For read-only transactions, obviously there is nothing to commit to
|
||||
storage. The transaction still must eventually be aborted to close
|
||||
any database handle(s) opened in it, or committed to keep the
|
||||
database handles around for reuse in new transactions.
|
||||
|
||||
In addition, as long as a transaction is open, a consistent view of
|
||||
the database is kept alive, which requires storage. A read-only
|
||||
transaction that no longer requires this consistent view should
|
||||
be terminated (committed or aborted) when the view is no longer
|
||||
needed (but see below for an optimization).
|
||||
|
||||
There can be multiple simultaneously active read-only transactions
|
||||
but only one that can write. Once a single read-write transaction
|
||||
is opened, all further attempts to begin one will block until the
|
||||
first one is committed or aborted. This has no effect on read-only
|
||||
transactions, however, and they may continue to be opened at any time.
|
||||
|
||||
@section dupkeys Duplicate Keys
|
||||
|
||||
#mdb_get() and #mdb_put() respectively have no and only some support
|
||||
for multiple key/value pairs with identical keys. If there are multiple
|
||||
values for a key, #mdb_get() will only return the first value.
|
||||
|
||||
When multiple values for one key are required, pass the #MDB_DUPSORT
|
||||
flag to #mdb_dbi_open(). In an #MDB_DUPSORT database, by default
|
||||
#mdb_put() will not replace the value for a key if the key existed
|
||||
already. Instead it will add the new value to the key. In addition,
|
||||
#mdb_del() will pay attention to the value field too, allowing for
|
||||
specific values of a key to be deleted.
|
||||
|
||||
Finally, additional cursor operations become available for
|
||||
traversing through and retrieving duplicate values.
|
||||
|
||||
@section optim Some Optimization
|
||||
|
||||
If you frequently begin and abort read-only transactions, as an
|
||||
optimization, it is possible to only reset and renew a transaction.
|
||||
|
||||
#mdb_txn_reset() releases any old copies of data kept around for
|
||||
a read-only transaction. To reuse this reset transaction, call
|
||||
#mdb_txn_renew() on it. Any cursors in this transaction must also
|
||||
be renewed using #mdb_cursor_renew().
|
||||
|
||||
Note that #mdb_txn_reset() is similar to #mdb_txn_abort() and will
|
||||
close any databases you opened within the transaction.
|
||||
|
||||
To permanently free a transaction, reset or not, use #mdb_txn_abort().
|
||||
|
||||
@section cleanup Cleaning Up
|
||||
|
||||
For read-only transactions, any cursors created within it must
|
||||
be closed using #mdb_cursor_close().
|
||||
|
||||
It is very rarely necessary to close a database handle, and in
|
||||
general they should just be left open.
|
||||
|
||||
@section onward The Full API
|
||||
|
||||
The full \ref mdb documentation lists further details, like how to:
|
||||
|
||||
\li size a database (the default limits are intentionally small)
|
||||
\li drop and clean a database
|
||||
\li detect and report errors
|
||||
\li optimize (bulk) loading speed
|
||||
\li (temporarily) reduce robustness to gain even more speed
|
||||
\li gather statistics about the database
|
||||
\li define custom sort orders

.SH DESCRIPTION
|
||||
The
|
||||
.B mdb_load
|
||||
utility reads from the standard input and loads it into the
|
||||
LMDB environment
|
||||
.BR envpath .
|
||||
|
||||
The input to
|
||||
.B mdb_load
|
||||
must be in the output format specified by the
|
||||
.BR mdb_dump (1)
|
||||
utility or as specified by the
|
||||
.B -T
|
||||
option below.
|
||||
.SH OPTIONS
|
||||
.TP
|
||||
.BR \-V
|
||||
Write the library version number to the standard output, and exit.
|
||||
.TP
|
||||
.BR \-f \ file
|
||||
Read from the specified file instead of from the standard input.
|
||||
.TP
|
||||
.BR \-n
|
||||
Load an LMDB database which does not use subdirectories.
|
||||
.TP
|
||||
.BR \-s \ subdb
|
||||
Load a specific subdatabase. If no database is specified, data is loaded into the main database.
|
||||
.TP
|
||||
.BR \-N
|
||||
Don't overwrite existing records when loading into an already existing database; just skip them.
|
||||
.TP
|
||||
.BR \-T
|
||||
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
|
||||
.BR mdb_load .
|
||||
|
||||
.SH DIAGNOSTICS
|
||||
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.

Display information about the environment reader table.
|
||||
Shows the process ID, thread ID, and transaction ID for each active
|
||||
reader slot. The process ID and transaction ID are in decimal, the
|
||||
thread ID is in hexadecimal. The transaction ID is displayed as "-"
|
||||
if the reader does not currently have a read transaction open.
|
||||
If \fB\-rr\fP is given, check for stale entries in the reader
|
||||
table and clear them. The reader table will be printed again
|
||||
after the check is performed.

Display the status of a specific subdatabase.
|
||||
.SH DIAGNOSTICS
|
||||
Exit status is zero if no errors occur.
|
||||
Errors result in a non-zero exit status and
|

.SH NAME
|
||||
mdb_copy \- LMDB environment copy tool
|
||||
.SH SYNOPSIS
|
||||
.B mdb_copy
|
||||
[\c
|
||||
.BR \-V ]
|
||||
[\c
|
||||
.BR \-c ]

||||
.BR \-n ]
|

.B srcpath
|
||||
[\c
|
||||
.BR dstpath ]
|
||||
.SH DESCRIPTION
|
||||
The
|
||||
.B mdb_copy
|
||||
utility copies an LMDB environment. The environment can
|
||||
be copied regardless of whether it is currently in use.
|
||||
No lockfile is created, since it gets recreated at need.
|
||||
|
||||
If
|
||||
.I dstpath
|
||||
is specified it must be the path of an empty directory
|
||||
for storing the backup. Otherwise, the backup will be
|
||||
written to stdout.
|
||||
|
||||
.SH OPTIONS
|
||||
.TP
|
||||
.BR \-V
|
||||
Write the library version number to the standard output, and exit.
|
||||
.TP
|
||||
.BR \-c
|
||||
Compact while copying. Only current data pages will be copied; freed
|
||||
or unused pages will be omitted from the copy. This option will
|
||||
slow down the backup process as it is more CPU-intensive.
|
||||
.TP
|
||||
.BR \-n
|
||||
Open LDMB environment(s) which do not use subdirectories.
|
||||
|
||||
.SH DIAGNOSTICS
|
||||
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.
|
||||
.SH CAVEATS
|
||||
This utility can trigger significant file size growth if run
|
||||
in parallel with write transactions, because pages which they
|
||||
free during copying cannot be reused until the copy is done.

|

.SH DESCRIPTION
|
||||
The
|
||||
.B mdb_dump
|
||||
utility reads a database and writes its contents to the
|
||||
standard output using a portable flat-text format
|
||||
understood by the
|
||||
.BR mdb_load (1)
|
||||
utility.
|
||||
.SH OPTIONS
|
||||
.TP
|
||||
.BR \-V
|
||||
Write the library version number to the standard output, and exit.
|
||||
.TP
|
||||
.BR \-f \ file
|
||||
Write to the specified file instead of to the standard output.
|
||||
.TP
|
||||
.BR \-l
|
||||
List the databases stored in the environment. Just the
|
||||
names will be listed, no data will be output.
|
||||
.TP
|
||||
.BR \-n
|
||||
Dump an LMDB database which does not use subdirectories.
|
||||
.TP
|
||||
.BR \-p
|
||||
If characters in either the key or data items are printing characters (as
|
||||
defined by isprint(3)), output them directly. This option permits users to
|
||||
use standard text editors and tools to modify the contents of databases.
|
||||
|
||||
Note: different systems may have different notions about what characters
|
||||
are considered printing characters, and databases dumped in this manner may
|
||||
be less portable to external systems.
|
||||
.TP
|
||||
.BR \-a
|
||||
Dump all of the subdatabases in the environment.
|
||||
.TP
|
||||
.BR \-s \ subdb
|
||||
Dump a specific subdatabase. If no database is specified, only the main database is dumped.
|
||||
.SH DIAGNOSTICS
|
||||
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.
|
||||
|
||||
Dumping and reloading databases that use user-defined comparison functions
|
||||
will result in new databases that use the default comparison functions.
|
||||
\fBIn this case it is quite likely that the reloaded database will be
|
||||
damaged beyond repair permitting neither record storage nor retrieval.\fP
|
||||
|
||||
The only available workaround is to modify the source for the
|
||||
.BR mdb_load (1)
|
||||
utility to load the database using the correct comparison functions.
