/*
|
||||
package bbolt implements a low-level key/value store in pure Go. It supports
|
||||
fully serializable transactions, ACID semantics, and lock-free MVCC with
|
||||
multiple readers and a single writer. Bolt can be used for projects that
|
||||
want a simple data store without the need to add large dependencies such as
|
||||
Postgres or MySQL.
|
||||
|
||||
Bolt is a single-level, zero-copy, B+tree data store. This means that Bolt is
|
||||
optimized for fast read access and does not require recovery in the event of a
|
||||
system crash. Transactions which have not finished committing will simply be
|
||||
rolled back in the event of a crash.
|
||||
|
||||
The design of Bolt is based on Howard Chu's LMDB database project.
|
||||
|
||||
Bolt currently works on Windows, Mac OS X, and Linux.
|
||||
|
||||
|
||||
Basics
|
||||
|
||||
There are only a few types in Bolt: DB, Bucket, Tx, and Cursor. The DB is
|
||||
a collection of buckets and is represented by a single file on disk. A bucket is
|
||||
a collection of unique keys that are associated with values.
|
||||
|
||||
Transactions provide either read-only or read-write access to the database.
|
||||
Read-only transactions can retrieve key/value pairs and can use Cursors to
|
||||
iterate over the dataset sequentially. Read-write transactions can create and
|
||||
delete buckets and can insert and remove keys. Only one read-write transaction
|
||||
is allowed at a time.
|
||||
|
||||
|
||||
Caveats
|
||||
|
||||
The database uses a read-only, memory-mapped data file to ensure that
|
||||
applications cannot corrupt the database, however, this means that keys and
|
||||
values returned from Bolt cannot be changed. Writing to a read-only byte slice
|
||||
will cause Go to panic.
|
||||
|
||||
Keys and values retrieved from the database are only valid for the life of
|
||||
the transaction. When used outside the transaction, these byte slices can
|
||||
point to different data or can point to invalid memory which will cause a panic.
