<h3>NAME</h3>
tokudb_file_map: map TokuDB tables to files and common shell commands
<h3>TYPE</h3>
View
<h3>DESCRIPTION</h3>
<p></p>
<p><i>tokudb_file_map</i> provides a per table listing of underlying TokuDB files.
</p>
<p>
TokuDB generates a file per index in table. For a partitioned table, that's one file per index per partition,
and in any case this amounts to multiple files per table.
<br/>TokuDB provides with the INFORMATION_SCHEMA.TokuDB_file_map view; however it is not normalized, and only maps
an internal TokuDB entity to file name.
</p>
<p>
<i>common_schema</i>'s <i>tokudb_file_map</i> lists the files on a per table basis, answering the common question of
<i>"which files represent my table?".</i>
<br/>It also adds common shell queries to answer questions such as <i>"what is the total size of files for my table?"</i>
</p>
<h3>STRUCTURE</h3>
<blockquote><pre>
mysql> DESC tokudb_file_map;
+--------------+------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+--------------+------------+------+-----+---------+-------+
| table_schema | text | YES | | NULL | |
| table_name | text | YES | | NULL | |
| count_files | bigint(21) | NO | | 0 | |
| files | mediumtext | YES | | NULL | |
| bash_ls | mediumtext | YES | | NULL | |
| bash_du | mediumtext | YES | | NULL | |
+--------------+------------+------+-----+---------+-------+
</pre></blockquote>
<h3>SYNOPSIS</h3>
<p>Columns of this view:
<ul>
<li><strong>table_schema</strong>: schema of TokuDB table.</li>
<li><strong>table_name</strong>: TokuDB table name.</li>
<li><strong>count_files</strong>: number of files representing this table.</li>
<li><strong>files</strong>: comma delimited list of files representing this table.</li>
<li><strong>bash_ls</strong>: shell <strong>ls</strong> command to show files of this table.</li>
<li><strong>bash_du</strong>: shell <strong>du</strong> command to present total size of files representing this table.</li>
</ul>
Shell commands are to be executed from within the <strong>@@datadir</strong> path, and require file system privileges; this is outside
MySQL's scope.
</p>
<h3>EXAMPLES</h3>
<p>List TokuDB files for a given table:</p>
<blockquote><pre>mysql> select * from tokudb_file_map where table_name='my_table' \G
