<div class="block">Get maximum default range size of a file being split during IGFS task execution. When IGFS task is about to

has length. In case this parameter is set to positive value, then IGFS will split single file range into smaller
ranges with length not greater that this parameter. The only exception to this case is when maximum task range
length is smaller than file block size. In this case maximum task range size will be overridden and set to file
block size.
<p>
Note that this parameter is applied when task is split into jobs before <a href="../../../../org/apache/ignite/igfs/mapreduce/IgfsRecordResolver.html" title="interface in org.apache.ignite.igfs.mapreduce"><code>IgfsRecordResolver</code></a> is
applied. Therefore, final file ranges being assigned to particular jobs could be greater than value of this
parameter depending on file data layout and selected resolver type.
<p>
Setting this parameter might be useful when file is highly colocated and have very long consequent data chunks
so that task execution suffers from insufficient parallelism. E.g., in case you have one IGFS node in topology
and want to process 1Gb file, then only single range of length 1Gb will be returned. This will result in
a single job which will be processed in one thread. But in case you provide this configuration parameter and set
maximum range length to 16Mb, then 64 ranges will be returned resulting in 64 jobs which could be executed in
parallel.
<p>
Note that some <code>IgniteFs.execute()</code> methods can override value of this parameter.

In case value of this parameter is set to <code>0</code> or negative value, it is simply ignored. Default value is

<p>
Normally Ignite spread ownership of particular keys among all cache nodes. Transaction with keys owned by
different nodes will produce more network traffic and will require more time to complete comparing to
transaction with keys owned only by a single node.
<p>
IGFS stores information about file system structure (metadata) inside a transactional cache configured through
<a href="../../../../org/apache/ignite/configuration/FileSystemConfiguration.html#getMetaCacheConfiguration()"><code>getMetaCacheConfiguration()</code></a> property. Metadata updates caused by operations on IGFS usually require
several internal keys to be updated. As IGFS metadata cache usually operates
in <a href="../../../../org/apache/ignite/cache/CacheMode.html#REPLICATED"><code>CacheMode.REPLICATED</code></a> mode, meaning that all nodes have all metadata locally, it makes sense to give
a hint to Ignite to co-locate ownership of all metadata keys on a single node.
This will decrease amount of network trips required to update metadata and hence could improve performance.
<p>
This property should be disabled if you see excessive CPU and network load on a single node, which
degrades performance and cannot be explained by business logic of your application.
<p>
This settings is only used if metadata cache is configured in <code>CacheMode#REPLICATED</code> mode. Otherwise it
is ignored.

<p>
Concurrent file system operations might conflict with each other. E.g. <code>move("/a1/a2", "/b")</code> and
<code>move("/b", "/a1")</code>. Hence, it is necessary to atomically verify that participating paths are still
on their places to keep file system in consistent state in such cases. These checks are expensive in
distributed environment.
<p>
Real applications, e.g. Hadoop jobs, rarely produce conflicting operations. So additional checks could be
skipped in these scenarios without any negative effect on file system integrity. It significantly increases
performance of file system operations.
<p>
If value of this flag is <code>true</code>, IGFS will skip expensive consistency checks. It is recommended to set
this flag to <code>false</code> if your application has conflicting operations, or you do not how exactly users will
use your system.
