Example 4 with CosmosQueryRequestOptions

use of com.azure.cosmos.models.CosmosQueryRequestOptions in project YCSB by brianfrankcooper.

the class AzureCosmosClient method scan.

/**
 * Perform a range scan for a set of records in the database. Each field/value
 * pair from the result will be stored in a HashMap.
 *
 * @param table       The name of the table
 * @param startkey    The record key of the first record to read.
 * @param recordcount The number of records to read
 * @param fields      The list of fields to read, or null for all of them
 * @param result      A Vector of HashMaps, where each HashMap is a set
 *                    field/value pairs for one record
 * @return Zero on success, a non-zero error code on error
