Examples with SolrIndexWriter org.apache.solr.update.SolrIndexWriter used on opensource projects

Example 1 with SolrIndexWriter

use of org.apache.solr.update.SolrIndexWriter in project lucene-solr by apache.

the class SolrSnapshotManager method deleteSnapshotIndexFiles.

/**
   * This method deletes index files of the {@linkplain IndexCommit} for the specified generation number.
   *
   * @param core The Solr core
   * @param dir The index directory storing the snapshot.
   * @throws IOException in case of I/O errors.
   */

    IndexWriterConfig conf = core.getSolrConfig().indexConfig.toIndexWriterConfig(core);
    conf.setOpenMode(OpenMode.APPEND);
    //Don't want to merge any commits here!
    conf.setMergePolicy(NoMergePolicy.INSTANCE);

    conf.setCodec(core.getCodec());
    try (SolrIndexWriter iw = new SolrIndexWriter("SolrSnapshotCleaner", dir, conf)) {
    // Do nothing. The only purpose of opening index writer is to invoke the Lucene IndexDeletionPolicy#onInit
    // method so that we can cleanup the files associated with specified index commit.
    // Note the index writer creates a new commit during the close() operation (which is harmless).
    }

Example 2 with SolrIndexWriter

use of org.apache.solr.update.SolrIndexWriter in project lucene-solr by apache.

the class SolrCore method initIndex.
