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.

Note

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

<shardIndexRecordBatchSize>The number amount of batch index records the indexing node should process per each indexing thread at a given time.

An index record contains data of a record batch inserted in a single put operation. This batch can be as high as the event receiver queue data size, which is 10MB by default. Therefore, the highest amount of in-memory record data that an indexing processing thread can have is 10MB * 100. This parameter should be configured to change the maximum amount of memory available to the indexing node based on your requirement.

100index data (in bytes) to be processed at a time by a shard index worker. Minimum value is 1000.

<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).
