buildIndexClusteringPrefix(java.nio.ByteBuffer partitionKey,
ClusteringPrefix<T> prefix,
CellPath path)
Used to construct an the clustering for an entry in the index table based on values from the base data.
|
IndexEntry |
decodeEntry(DecoratedKey indexedValue,
Row indexEntry)
Used at search time to convert a row in the index table into a simple struct containing the values required
to retrieve the corresponding row from the base table.
|
java.nio.ByteBuffer |
getIndexedValue(java.nio.ByteBuffer partitionKey,
Clustering<?> clustering,
CellPath path,
java.nio.ByteBuffer cellValue)
Extract the value to be inserted into the index from the components of the base data
|
boolean |
isStale(Row data,
java.nio.ByteBuffer indexValue,
int nowInSec)
Check whether a value retrieved from an index is still valid by comparing it to current row from the base table.
|
boolean |
supportsOperator(ColumnMetadata indexedColumn,
Operator operator)
Returns true if an index of this type can support search predicates of the form [column] OPERATOR [value]
