storr_thor

driver_thor

Storr driver for thor. This allows thor to be used as a storage
backend with the storr package and presents a higher level content
addressable key/value store suitable for storing R objects.

Key-value store, implemented as a wrapper around 'LMDB';
the "lightning memory-mapped database" <https://www.symas.com/lmdb>.
'LMDB' is a transactional key value store that uses a memory map
for efficient access. This package wraps the entire 'LMDB'
interface (except duplicated keys), and provides objects for
transactions and cursors.

storr_thor function

<dl><dt>env</dt>
<dd>A thor environment</dd>
<dt>prefix</dt>
<dd>An optional prefix. If given, use a <code>:</code> as the
last character for nice looking keys (e.g., <code>storr:</code> will
generate keys like <code>storr:keys:namespace:name</code>. If not
given then we assume that storr is the only user of this
database and if <code>destroy</code> is called it will delete the
entire database.</dd>
<dt>hash_algorithm</dt>
<dd>Optional hash algorithm to use. Defaults to
md5, or whatever the existing algorithm is if the database has
been opened. You cannot mix algorithms.</dd>
<dt>default_namespace</dt>
<dd>The default namespace to store objects
in. Defaults to <code>objects</code>, as does other storr drivers.</dd></dl>
