+<p>Use file access properties to modify the default behavior of the HDF5 library when accessing files. The properties include selecting a virtual file driver (VFD), configuring the metadata cache (MDC), control file locking, etc. These properties are <em>not</em> persisted with files, and can be adjusted at runtime before a file is created or opened.</p>

+<p>The metadata cache is a central part of the HDF5 library through which all file metadata reads and writes take place. File metadata is normally invisible to the user and is used by the library for purposes such as locating and indexing data. File metadata should not be confused with user metadata, which consists of attributes created by users and attached to HDF5 objects such as datasets via <a class="el" href="group___h5_a.html">Attributes (H5A)</a> API calls.</p>
+<p>Due to the complexity of the cache, a trace/logging feature has been created that can be used by HDF5 developers for debugging and performance analysis. The functions that control this functionality will normally be of use to a very limited number of developers outside of The HDF Group. The functions have been documented to help users create logs that can be sent with bug reports.</p>
+<p>Control of the log functionality is straightforward. Logging is enabled via the <a class="el" href="group___f_a_p_l.html#ga4d7206c5679d7243410058eceae59b2c" title="Sets metadata cache logging options.">H5Pset_mdc_log_options()</a> function, which will modify the file access property list used to open or create a file. This function has a flag that determines whether logging begins at file open or starts in a paused state. Log messages can then be controlled via the <a class="el" href="group___m_d_c.html#ga378fb5863071278b47070cf205f53e67" title="Starts logging metadata cache events if logging was previously enabled.">H5Fstart_mdc_logging()</a> / <a class="el" href="group___m_d_c.html#ga78627b23010f82002b837f4d312bf234" title="Stops logging metadata cache events if logging was previously enabled and is currently ongoing.">H5Fstop_mdc_logging()</a> functions. <a class="el" href="group___f_a_p_l.html#gaa3a1ca6e294cc5074933239cc3d0e4a3" title="Gets metadata cache logging options.">H5Pget_mdc_log_options()</a> can be used to examine a file access property list, and <a class="el" href="group___m_d_c.html#ga998ebdc7b5190cf3d0fdf2fbe71e9780" title="Gets the current metadata cache logging status.">H5Fget_mdc_logging_status()</a> will return the current state of the logging flags.</p>
+<p>The log format is described in the <a href="https://bit.ly/2PG6fNv">Metadata Cache Logging</a> document.</p>

+<p>The raw data chunk cache inserts chunks into the cache by first computing a hash value using the address of a chunk and then by using that hash value as the chunk’s index into the table of cached chunks. In other words, the size of this hash table and the number of possible hash values are determined by the <code>rdcc_nslots</code> parameter. If a different chunk in the cache has the same hash value, a collision will occur, which will reduce efficiency.

+<p>The default external link open file cache size is 0 (zero), meaning that files accessed via an external link are not held open. Setting the cache size to a positive integer turns on the cache; setting the size back to zero turns it off.</p>
+<p>With this property set, files are placed in the external link open file cache cache when they are opened via an external link. Files are then held open until either they are evicted from the cache or the parent file is closed. This property setting can improve performance when external links are repeatedly accessed.</p>
+<p>When the cache is full, files will be evicted using a least recently used (LRU) scheme; the file which has gone the longest time without being accessed through the parent file will be evicted and closed if nothing else is holding that file open.</p>
+<p>Files opened through external links inherit the parent file’s file access property list by default, and therefore inherit the parent file’s external link open file cache setting.</p>
+<p>When child files contain external links of their own, the caches can form a graph of cached external files. Closing the last external reference to such a graph will recursively close all files in the graph, even if cycles are present. </p><dl class="section user"><dt>Example</dt><dd><p class="startdd">The following code sets up an external link open file cache that will hold open up to 8 files reached through external links:</p>

+<p>Dataset region references and other reference types use space in an HDF5 file's global heap. If garbage collection is on and the user passes in an uninitialized value in a reference structure, the heap might get corrupted. When garbage collection is off, however, and the user re-uses a reference, the previous heap block will be orphaned and not returned to the free heap space.</p>
+<p>When garbage collection is on, the user must initialize the reference structures to 0 or risk heap corruption.</p>

Rather than fail the subsequent file open, the library silently ignores the file image request in this case.<br  />
+ It is also an error to request a cache image on a file that does not support superblock extension messages (i.e. a superblock version less than 2). As above, it is not always possible to detect this error in the <a class="el" href="group___f_a_p_l.html#ga65cf9fea33d1324009efc2d5db848434" title="Sets the metadata cache image option for a file access property list.">H5Pset_mdc_image_config()</a> call, and thus the request for a cache image will fail silently in this case as well.<br  />
+ Creation of cache images is currently disabled in parallel &ndash; as above, any request for a cache image in this context will fail silently.<br  />
+ Files with cache images may be read in parallel applications, but note that the load of the cache image is a collective operation triggered by the first operation that accesses metadata after file open (or, if persistent free space managers are enabled, on the first allocation or deallocation of file space, or read of file space manager status, whichever comes first). Thus the parallel process may deadlock if any process does not participate in this access.<br  />
+ In long sequences of file closes and opens, infrequently accessed metadata can accumulate in the cache image to the point where the cost of storing and restoring this metadata exceeds the benefit of retaining frequently used metadata in the cache image. When implemented, the <a class="el" href="struct_h5_a_c__cache__image__config__t.html#aec92d40c46311615f2155573aca27ec4">H5AC_cache_image_config_t::entry_ageout</a> should address this problem. In the interim, not requesting a cache image every n file close/open cycles may be an acceptable work around. The choice of <code>n</code> will be driven by application behavior, but <code>n = 10</code> seems a good starting point.</dd></dl>

+<p>The metadata cache is a central part of the HDF5 library through which all file metadata reads and writes take place. File metadata is normally invisible to the user and is used by the library for purposes such as locating and indexing data. File metadata should not be confused with user metadata, which consists of attributes created by users and attached to HDF5 objects such as datasets via H5A API calls.</p>
+<p>Due to the complexity of the cache, a trace/logging feature has been created that can be used by HDF5 developers for debugging and performance analysis. The functions that control this functionality will normally be of use to a very limited number of developers outside of The HDF Group. The functions have been documented to help users create logs that can be sent with bug reports.</p>
+<p>Control of the log functionality is straightforward. Logging is enabled via the <a class="el" href="group___f_a_p_l.html#ga4d7206c5679d7243410058eceae59b2c" title="Sets metadata cache logging options.">H5Pset_mdc_log_options()</a> function, which will modify the file access property list used to open or create a file. This function has a flag that determines whether logging begins at file open or starts in a paused state. Log messages can then be controlled via the <a class="el" href="group___m_d_c.html#ga378fb5863071278b47070cf205f53e67" title="Starts logging metadata cache events if logging was previously enabled.">H5Fstart_mdc_logging()</a> and <a class="el" href="group___m_d_c.html#ga78627b23010f82002b837f4d312bf234" title="Stops logging metadata cache events if logging was previously enabled and is currently ongoing.">H5Fstop_mdc_logging()</a> function.</p>

+<p>The data sieve buffer is used when performing I/O on datasets in the file. Using a buffer which is large enough to hold several pieces of the dataset being read in for hyperslab selections boosts performance by quite a bit.</p>
+<p>The default value is set to 64KB, indicating that file I/O for raw data reads and writes will occur in at least 64KB blocks. Setting the value to zero (<code>0</code>) with this API function will turn off the data sieving, even if the VFL driver attempts to use that strategy.</p>
+<p>Internally, the library checks the storage sizes of the datasets in the file. It picks the smaller one between the size from the file access property and the size of the dataset to allocate the sieve buffer for the dataset in order to save memory usage.</p>

The HDF5 library then writes the raw data from small datasets to this reserved space, thus reducing unnecessary discontinuities within blocks of meta data and improving I/O performance.</p>
+<p>A small data block is actually allocated the first time a qualifying small dataset is written to the file. Space for the raw data portion of this small dataset is suballocated within the small data block. The raw data from each subsequent small dataset is also written to the small data block until it is filled; additional small data blocks are allocated as required.</p>
+<p>The HDF5 library employs an algorithm that determines whether I/O performance is likely to benefit from the use of this mechanism with each dataset as storage space is allocated in the file. A larger <code>size</code> will result in this mechanism being employed with larger datasets.</p>
+<p>The small data block size is set as an allocation property in the file access property list identified by <code>fapl_id</code>.</p>
