Method Detail

consistencyLevel

public QueryOptions.QueryOptionsBuilder consistencyLevel(com.datastax.oss.driver.api.core.ConsistencyLevel consistencyLevel)

Sets the ConsistencyLevel to use.

Parameters:

consistencyLevel - must not be null.

Returns:

this QueryOptions.QueryOptionsBuilder

executionProfile

public QueryOptions.QueryOptionsBuilder executionProfile(String profileName)

Sets the execution profile to use.

Parameters:

profileName - must not be null or empty.

Returns:

this QueryOptions.QueryOptionsBuilder

Since:

3.0

See Also:

Statement.setExecutionProfileName(String)

executionProfile

public QueryOptions.QueryOptionsBuilder executionProfile(ExecutionProfileResolver executionProfileResolver)

Sets the ExecutionProfileResolver to use.

Parameters:

executionProfileResolver - must not be null.

Returns:

this QueryOptions.QueryOptionsBuilder

See Also:

Statement.setExecutionProfile(DriverExecutionProfile)

fetchSize

@Deprecated
public QueryOptions.QueryOptionsBuilder fetchSize(int fetchSize)

Deprecated. since 3.0, use pageSize(int).

Sets the query fetch size for ResultSet chunks.

The fetch size controls how much resulting rows will be retrieved simultaneously (the goal being to avoid loading too much results in memory for queries yielding large results). Please note that while value as low as 1 can be used, it is *highly* discouraged to use such a low value in practice as it will yield very poor performance.

Parameters:

fetchSize - the number of rows to fetch per chunking request. To disable chunking of the result set, use fetchSize == Integer.MAX_VALUE. Negative values are not allowed.

Returns:

this QueryOptions.QueryOptionsBuilder

keyspace

public QueryOptions.QueryOptionsBuilder keyspace(com.datastax.oss.driver.api.core.CqlIdentifier keyspace)

Sets the keyspace to use. If left unconfigured, then the keyspace set on the statement or CqlSession will be used.

Parameters:

keyspace - the specific keyspace to use to run a statement, must not be null.

Returns:

this QueryOptions.QueryOptionsBuilder.

Since:

3.1

pageSize

public QueryOptions.QueryOptionsBuilder pageSize(int pageSize)

Sets the query fetch size for ResultSet chunks.

The fetch size controls how much resulting rows will be retrieved simultaneously (the goal being to avoid loading too much results in memory for queries yielding large results). Please note that while value as low as 1 can be used, it is *highly* discouraged to use such a low value in practice as it will yield very poor performance.

Parameters:

pageSize - the number of rows to fetch per chunking request. To disable chunking of the result set, use pageSize == Integer.MAX_VALUE. Negative values are not allowed.

Returns:

this QueryOptions.QueryOptionsBuilder

readTimeout

@Deprecated
public QueryOptions.QueryOptionsBuilder readTimeout(long readTimeout)

Deprecated. since 3.0, use timeout(Duration)

Sets the read timeout in milliseconds. Overrides the default per-host read timeout.

Parameters:

readTimeout - the read timeout in milliseconds. Negative values are not allowed. If it is 0, the read timeout will be disabled for this statement.

Returns:

this QueryOptions.QueryOptionsBuilder

See Also:

Statement.setTimeout(Duration)

readTimeout

@Deprecated
public QueryOptions.QueryOptionsBuilder readTimeout(long readTimeout,
                                                                TimeUnit timeUnit)

Deprecated. since 2.0, use timeout(Duration).

Sets the read timeout. Overrides the default per-host read timeout.

Parameters:

readTimeout - the read timeout value. Negative values are not allowed. If it is 0, the read timeout will be disabled for this statement.

timeUnit - the TimeUnit for the supplied timeout; must not be null.

Returns:

this QueryOptions.QueryOptionsBuilder

See Also:

Statement.setTimeout(Duration)

readTimeout

@Deprecated
public QueryOptions.QueryOptionsBuilder readTimeout(Duration readTimeout)

Deprecated. since 3.0, use timeout(Duration)

Sets the read timeout. Overrides the default per-host read timeout.

Parameters:

readTimeout - the read timeout. Negative values are not allowed. If it is 0, the read timeout will be disabled for this statement.

Returns:

this QueryOptions.QueryOptionsBuilder

Since:

2.0

See Also:

Statement.setTimeout(Duration)

serialConsistencyLevel

public QueryOptions.QueryOptionsBuilder serialConsistencyLevel(com.datastax.oss.driver.api.core.ConsistencyLevel consistencyLevel)

Sets the serial ConsistencyLevel to use.

Parameters:

consistencyLevel - must not be null.

Returns:

this QueryOptions.QueryOptionsBuilder

timeout

public QueryOptions.QueryOptionsBuilder timeout(Duration timeout)

Sets the request timeout. Overrides the default timeout.

Parameters:

timeout - the read timeout. Negative values are not allowed. If it is 0, the read timeout will be disabled for this statement.

Returns:

this QueryOptions.QueryOptionsBuilder

Since:

3.0

See Also:

Statement.setTimeout(Duration)

tracing

public QueryOptions.QueryOptionsBuilder tracing(boolean tracing)

Enables statement tracing.

Parameters:

tracing - true to enable statement tracing to the executed statements.

Returns:

this QueryOptions.QueryOptionsBuilder

withTracing

public QueryOptions.QueryOptionsBuilder withTracing()

Enables statement tracing.

Returns:

this QueryOptions.QueryOptionsBuilder

build
