Introduction
Fredhopper Discovery Platform 23.3 is compatible with the previous release.
Navigation Index Sharding
Navigation Index Sharding is a new feature introduced in FAS 23.3 release. The feature is in Closed Beta (Available to select customers). This feature allows the navigation index to be split and populated on several shards. This will result in:
-
Reduced reindex time. Shards can be indexed in parallel, and since each shard has less data than the full navigation index, the indexing time is reduced.
-
Faster queries.
The feature is available only for:
-
customers that use multi-site efficiency.
-
customers with a single-universe configuration.
Navigation Index Sharding is configured in system.xml, in the node /com/fredhopper/tree/Sharding.
-
<entry key="enabled" value="true"/>- to enable sharding (disabled by default). -
<entry key="number-of-shards" value="5"/>- to specify the number of shards (2 or more). -
<entry key="shard-conflation-known-values" value="" />- allows to fine-tune the distribution of conflated values in the shards by using a weight-based algorithm. Weights are specified as a comma-separated list of conflated values, where each value can optionally have a weight assigned in the formatvalue:weight. If no weight is provided or the conflated value is not in the list, the weight it is automatically assigned to1.
