It does this more - * efficiently than creating a single segment per document - * (with DocumentWriter) and doing standard merges on those - * segments. - * - * Each added document is passed to the {@link DocConsumer}, - * which in turn processes the document and interacts with - * other consumers in the indexing chain. Certain - * consumers, like {@link StoredFieldsWriter} and {@link - * TermVectorsTermsWriter}, digest a document and - * immediately write bytes to the "doc store" files (ie, - * they do not consume RAM per document, except while they - * are processing the document). - * - * Other consumers, eg {@link FreqProxTermsWriter} and - * {@link NormsWriter}, buffer bytes in RAM and flush only - * when a new segment is produced. - - * Once we have used our allowed RAM buffer, or the number - * of added docs is large enough (in the case we are - * flushing by doc count instead of RAM usage), we create a - * real segment and flush it to the Directory. - * - * Threads: - * - * Multiple threads are allowed into addDocument at once. - * There is an initial synchronized call to getThreadState - * which allocates a ThreadState for this thread. The same - * thread will get the same ThreadState over time (thread - * affinity) so that if there are consistent patterns (for - * example each thread is indexing a different content - * source) then we make better use of RAM. Then - * processDocument is called on that ThreadState without - * synchronization (most of the "heavy lifting" is in this - * call). Finally the synchronized "finishDocument" is - * called to flush changes to the directory. - * - * When flush is called by IndexWriter we forcefully idle - * all threads and flush only once they are all idle. This - * means you can call flush with a given thread even while - * other threads are actively adding/deleting documents. - * - * - * Exceptions: - * - * Because this class directly updates in-memory posting - * lists, and flushes stored fields and term vectors - * directly to files in the directory, there are certain - * limited times when an exception can corrupt this state. - * For example, a disk full while flushing stored fields - * leaves this file in a corrupt state. Or, an OOM - * exception while appending to the in-memory posting lists - * can corrupt that posting list. We call such exceptions - * "aborting exceptions". In these cases we must call - * abort() to discard all docs added since the last flush. - * - * All other exceptions ("non-aborting exceptions") can - * still partially update the index structures. These - * updates are consistent, but, they represent only a part - * of the document seen up until the exception was hit. - * When this happens, we immediately mark the document as - * deleted so that the document is always atomically ("all - * or none") added to the index. + * Licensed to the Apache Software Foundation (ASF) under one or more + * contributor license agreements.
