The new Berkeley DB SQL API specific pragma
|
||
<code class="literal">bdbsql_log_buffer</code> has been added to
|
||
set the size of the Berkeley DB in-memory log buffer, in
|
||
bytes. This is useful for long-running transactions or
|
||
applications producing large amounts of data because a
|
||
larger log buffer can increase throughput.
