ParameterDescriptionDefault Value
<analytics-lucene-analyzer>

The implementation of the Analytics Lucene Analyzer is defined as a subelement of this parameter.

e.g.,  <implementation>org.apache.lucene.analysis.standard.StandardAnalyzer</implementation>

 
<indexReplicationFactor>The index data replication factor to be used in clustered mode. This tells how many replicas that should be kept when indexing operations are done. 0 means, no replication. It should be set to 1 or higher to have high availability.1
<shardCount>

The number of index shards the server should maintain per cluster. This fine tunes the scaling nature of the indexing cluster.that are allowed to exist in the local file system at a given time. The number specified should be higher than the number of indexing nodes in the DAS cluster. The ideal number can be calculated as follows.

number of indexing nodes * [CPU cores used for indexing per node]

Note

This parameter can only be set once for the lifetime of the cluster, and cannot be changed later on.


6
<shardIndexRecordBatchSize>The amount of index data (in bytes) to be processed at a time by a shard index worker. Minimum value is 1000.20971520

<shardIndexWorkerInterval>

The interval in milliseconds during which a shard index processing worker thread will sleep during index processing operations. This parameter together with the shardIndexRecordBatchSize parameter can be used to increase the final index batched data amount processed by the indexer at a given time. Usually, a higher batch data amount results in a higher throughput of the indexing operations. However, it also causes an increased latency of record insertion to indexing. Minimum value of this is 10, and a maximum value is 60000 (1 minute).
