/** @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

.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.

.SH DESCRIPTION
The
.B mdb_stat
utility displays the status of an LMDB environment.
.SH OPTIONS
.TP
.BR \-V
Write the library version number to the standard output, and exit.
.TP
.BR \-e
Display information about the database environment.
.TP
.BR \-f
Display information about the environment freelist.
If \fB\-ff\fP is given, summarize each freelist entry.
If \fB\-fff\fP is given, display the full list of page IDs in the freelist.
.TP
.BR \-n
Display the status of an LMDB database which does not use subdirectories.
.TP
.BR \-r
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.
.TP
.BR \-a
Display the status of all of the subdatabases in the environment.
.TP
.BR \-s \ subdb
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
a diagnostic message being written to standard error.

.\" Copyright 2012-2015 Howard Chu, Symas Corp. All Rights Reserved.
.\" Copying restrictions apply. See COPYRIGHT/LICENSE.
.SH NAME
mdb_copy \- LMDB environment copy tool
.SH SYNOPSIS
.B mdb_copy
[\c
.BR \-V ]
[\c
.BR \-c ]
[\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 "SEE ALSO"
.BR mdb_stat (1)

mdb_dump \- LMDB environment export tool

.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.
