Class DefaultStore

The default built-in IStore implementation. This stores data in the file system or in memory. It also uses LiteDB for some complex indices.

DefaultStore and DefaultKeyValueStore-backed TrieStateStore can be instantiated from a URI with default+file: scheme using LoadStore(Uri), e.g.:

• default+file:///var/data/planet/
• default+file:///c:/Users/john/AppData/Local/planet/

The following query string parameters are supported:

journal	true (default) or false. Corresponds to DefaultStore(String, Boolean, Int32, Int32, Int32, Boolean, Boolean)'s journal parameter.
index-cache	Corresponds to DefaultStore(String, Boolean, Int32, Int32, Int32, Boolean, Boolean)'s indexCacheSize parameter. 50000 by default.
block-cache	Corresponds to DefaultStore(String, Boolean, Int32, Int32, Int32, Boolean, Boolean)'s blockCacheSize parameter. 512 by default.
tx-cache	Corresponds to DefaultStore(String, Boolean, Int32, Int32, Int32, Boolean, Boolean)'s txCacheSize parameter. 1024 by default.
flush	true (default) or false. Corresponds to DefaultStore(String, Boolean, Int32, Int32, Int32, Boolean, Boolean)'s flush parameter.
readonly	true or false (default). Corresponds to DefaultStore(String, Boolean, Int32, Int32, Int32, Boolean, Boolean)'s readOnly parameter.
states-dir	Corresponds to DefaultKeyValueStore(String)'s path parameter. It is relative to the URI path, and defaults to states.
