Field Detail

DEFAULT_MERGE_SCHEDULER_CLASSNAME

public static final String DEFAULT_MERGE_SCHEDULER_CLASSNAME

useCompoundFile

public final boolean useCompoundFile

maxBufferedDocs

public final int maxBufferedDocs

ramBufferSizeMB

public final double ramBufferSizeMB

ramPerThreadHardLimitMB

public final int ramPerThreadHardLimitMB

maxCommitMergeWaitMillis

public final int maxCommitMergeWaitMillis

When using a custom merge policy that allows triggering synchronous merges on commit (see MergePolicy.findFullFlushMerges(org.apache.lucene.index.MergeTrigger, org.apache.lucene.index.SegmentInfos, org.apache.lucene.index.MergePolicy.MergeContext)), a timeout (in milliseconds) can be set for those merges to finish. Use <maxCommitMergeWaitTime>1000</maxCommitMergeWaitTime> in the <indexConfig> section. See IndexWriterConfig.setMaxFullFlushMergeWaitMillis(long).

Note that as of Solr 8.6, no MergePolicy shipped with Lucene/Solr make use of MergePolicy.findFullFlushMerges, which means this setting has no effect unless a custom MergePolicy is used.

public final PluginInfo mergePolicyFactoryInfo

mergeSchedulerInfo

public final PluginInfo mergeSchedulerInfo
