partitionRange
public List<DocRouter.Range> partitionRange(int partitions,
DocRouter.Range range)
- Returns the range for each partition
getTargetSlice
public abstract Slice getTargetSlice(String id,
SolrInputDocument sdoc,
SolrParams params,
DocCollection collection)
- Returns the Slice that the document should reside on, or null if there is not enough information
getSearchSlicesSingle
public abstract Collection<Slice> getSearchSlicesSingle(String shardKey,
SolrParams params,
DocCollection collection)
- This method is consulted to determine what slices should be queried for a request when
an explicit shards parameter was not used.
This method only accepts a single shard key (or null). If you have a comma separated list of shard keys,
call getSearchSlices
getSearchSlices
public Collection<Slice> getSearchSlices(String shardKeys,
SolrParams params,
DocCollection collection)
- This method is consulted to determine what slices should be queried for a request when
an explicit shards parameter was not used.
This method accepts a multi-valued shardKeys parameter (normally comma separated from the shard.keys request parameter)
and aggregates the slices returned by getSearchSlicesSingle for each shardKey.
