| 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 |

| Setting this parameter might be useful when file is highly colocated and have very long consequent data chunks |

| Normally Ignite spread ownership of particular keys among all cache nodes. Transaction with keys owned by |

| 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 |

| 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. |
