| <div class="block">Data streamer is responsible for streaming external data into cache. It achieves it by |
| properly buffering updates and properly mapping keys to nodes responsible for the data |
| to make sure that there is the least amount of data movement possible and optimal |
| network and memory utilization. |
| <p> |
| Note that streamer will stream data concurrently by multiple internal threads, so the |
| data may get to remote nodes in different order from which it was added to |
| the streamer. |
| <p> |
| Also note that <code>IgniteDataStreamer</code> is not the only way to add data into cache. |
| Alternatively you can use <a href="../../../org/apache/ignite/IgniteCache.html#loadCache(org.apache.ignite.lang.IgniteBiPredicate, java.lang.Object...)"><code>IgniteCache.loadCache(IgniteBiPredicate, Object...)</code></a> |
| method to add data from underlying data store. You can also use standard |
| cache <code>put(...)</code> and <code>putAll(...)</code> operations as well, but they most |
| likely will not perform as well as this class for adding data. And finally, |
| data can be added from underlying data store on demand, whenever it is accessed - |
| for this no explicit data adding step is needed. |
| <p> |
| <code>IgniteDataStreamer</code> supports the following configuration properties: |
| <ul> |
| <li> |
| <a href="../../../org/apache/ignite/IgniteDataStreamer.html#perNodeBufferSize(int)"><code>perNodeBufferSize(int)</code></a> - when entries are added to data streamer via |
| <a href="../../../org/apache/ignite/IgniteDataStreamer.html#addData(K, V)"><code>addData(Object, Object)</code></a> method, they are not sent to in-memory data grid right |
| away and are buffered internally for better performance and network utilization. |
| This setting controls the size of internal per-node buffer before buffered data |
| is sent to remote node. Default is defined by <a href="../../../org/apache/ignite/IgniteDataStreamer.html#DFLT_PER_NODE_BUFFER_SIZE"><code>DFLT_PER_NODE_BUFFER_SIZE</code></a> |
| value. |
| </li> |
| <li> |
| <a href="../../../org/apache/ignite/IgniteDataStreamer.html#perNodeParallelOperations(int)"><code>perNodeParallelOperations(int)</code></a> - sometimes data may be added |
| to the data streamer via <a href="../../../org/apache/ignite/IgniteDataStreamer.html#addData(K, V)"><code>addData(Object, Object)</code></a> method faster than it can |
| be put in cache. In this case, new buffered stream messages are sent to remote nodes |
| before responses from previous ones are received. This could cause unlimited heap |
| memory utilization growth on local and remote nodes. To control memory utilization, |
| this setting limits maximum allowed number of parallel buffered stream messages that |
| are being processed on remote nodes. If this number is exceeded, then |
| <a href="../../../org/apache/ignite/IgniteDataStreamer.html#addData(K, V)"><code>addData(Object, Object)</code></a> method will block to control memory utilization. |
| Default is defined by <a href="../../../org/apache/ignite/IgniteDataStreamer.html#DFLT_MAX_PARALLEL_OPS"><code>DFLT_MAX_PARALLEL_OPS</code></a> value. |
| </li> |
| <li> |
| <a href="../../../org/apache/ignite/IgniteDataStreamer.html#autoFlushFrequency(long)"><code>autoFlushFrequency(long)</code></a> - automatic flush frequency in milliseconds. Essentially, |
| this is the time after which the streamer will make an attempt to submit all data |
| added so far to remote nodes. Note that there is no guarantee that data will be |
| delivered after this concrete attempt (e.g., it can fail when topology is |
| changing), but it won't be lost anyway. Disabled by default (default value is <code>0</code>). |
| </li> |
| <li> |
| <a href="../../../org/apache/ignite/IgniteDataStreamer.html#allowOverwrite(boolean)"><code>allowOverwrite(boolean)</code></a> - defines if data streamer will assume that there are no other concurrent |
| updates and allow data streamer choose most optimal concurrent implementation. |
| </li> |
| <li> |
| <a href="../../../org/apache/ignite/IgniteDataStreamer.html#updater(org.apache.ignite.IgniteDataStreamer.Updater)"><code>updater(IgniteDataStreamer.Updater)</code></a> - defines how cache will be updated with added entries. |
| It allows to provide user-defined custom logic to update the cache in the most effective and flexible way. |
| </li> |
| <li> |
| <a href="../../../org/apache/ignite/IgniteDataStreamer.html#deployClass(java.lang.Class)"><code>deployClass(Class)</code></a> - optional deploy class for peer deployment. All classes |
| streamed by a data streamer must be class-loadable from the same class-loader. |
| Ignite will make the best effort to detect the most suitable class-loader |
| for data loading. However, in complex cases, where compound or deeply nested |
| class-loaders are used, it is best to specify a deploy class which can be any |
| class loaded by the class-loader for given data. |
