Examples with Cells com.palantir.atlasdb.keyvalue.impl.Cells used on opensource projects

Example 1 with Cells

use of com.palantir.atlasdb.keyvalue.impl.Cells in project atlasdb by palantir.

the class CassandraKeyValueServiceImpl method addGarbageCollectionSentinelValues.

/**
 * Adds a value with timestamp = Value.INVALID_VALUE_TIMESTAMP to each of the given cells. If
 * a value already exists at that time stamp, nothing is written for that cell.
 * <p>
 * Does not require all Cassandra nodes to be up and available, works as long as quorum is achieved.
 *
 * @param tableRef the name of the table to add the value to.
 * @param cells a set of cells to store the values in.
