Documentation

Overview

Package boltdb implements a store.KVStore on top of BoltDB. It supports the following options:

"bucket" (string): the name of BoltDB bucket to use, defaults to "bleve".

"nosync" (bool): if true, set boltdb.DB.NoSync to true. It speeds up index operations in exchange of losing integrity guarantees if indexation aborts without closing the index. Use it when rebuilding indexes from zero.
