Connection String Options

The connection string properties are the various options that can be used to establish a connection. This section provides a complete list of the options you can configure in the connection string for this provider. Click the links for further details.

For more information on establishing a connection, see Establishing a Connection.
Auth SchemeThe scheme used for authentication. Accepted entries are: Auto, , AwsRootKeys , AwsIAMRoles , AwsEC2Roles , AwsMFA , AwsCredentialsFile.
Auto CacheAutomatically caches the results of SELECT queries into a cache database specified by either CacheLocation or both of CacheConnection and CacheProvider .
Auto Detect IndexA boolean indicating if secondary indexes should be automatically detected based on the query used.
AWS Access KeyYour AWS account access key. This value is accessible from your AWS security credentials page.
AWS External IdA unique identifier that might be required when you assume a role in another account.
AWS RegionThe hosting region for your Amazon Web Services.
AWS Role ARNThe Amazon Resource Name of the role to use when authenticating.
AWS Secret KeyYour AWS account secret key. This value is accessible from your AWS security credentials page.
AWS Session TokenYour AWS session token.
Batch SizeThe maximum size of each batch operation to submit.
Buffer SizeDetermines the internal buffer size to fill up to before returning results.
Cache ConnectionThe connection string for the cache database. This property is always used in conjunction with CacheProvider . Setting both properties will override the value set for CacheLocation for caching data.
Cache DriverThe database driver to be used to cache data.
Cache LocationSpecifies the path to the cache when caching to a file.
Cache MetadataThis property determines whether or not to cache the table metadata to a file store.
Cache ToleranceThe tolerance for stale data in the cache specified in seconds when using AutoCache .
Connection Life TimeThe maximum lifetime of a connection in seconds. Once the time has elapsed, the connection object is disposed.
Connect On OpenThis property species whether to connect to the Amazon DynamoDB when the connection is opened.
Credentials LocationThe location of the settings file where MFA credentials are saved.
DomainYour AWS domain name. You can optionally choose to associate your domain name with AWS.
Firewall PasswordA password used to authenticate to a proxy-based firewall.
Firewall PortThe TCP port for a proxy-based firewall.
Firewall ServerThe name or IP address of a proxy-based firewall.
Firewall TypeThe protocol used by a proxy-based firewall.
Firewall UserThe user name to use to authenticate with a proxy-based firewall.
Flatten ArraysBy default, nested arrays are returned as strings of JSON. The FlattenArrays property can be used to flatten the elements of nested arrays into columns of their own. Set FlattenArrays to the number of elements you want to return from nested arrays.
Flatten ObjectsSet FlattenObjects to true to flatten object properties into columns of their own. Otherwise, objects nested in arrays are returned as strings of JSON.
Generate Schema FilesIndicates the user preference as to when schemas should be generated and saved.
Insert ModeHow to handle values when inserting if the same primary key combination already exists in DynamoDB.
LocationA path to the directory that contains the schema files defining tables, views, and stored procedures.
LogfileA filepath which designates the name and location of the log file.
Log ModulesCore modules to be included in the log file.
Maximum Request RetriesThe maximum number of times to retry a request.
Max Log File CountA string specifying the maximum file count of log files. When the limit is hit, a new log is created in the same folder with the date and time appended to the end and the oldest log file will be deleted.
Max Log File SizeA string specifying the maximum size in bytes for a log file (for example, 10 MB). When the limit is hit, a new log is created in the same folder with the date and time appended to the end.
Max RowsLimits the number of rows returned rows when no aggregation or group by is used in the query. This helps avoid performance issues at design time.
MFA Serial NumberThe serial number of the MFA device if one is being used.
MFA TokenThe temporary token available from your MFA device.
Number Column ModeSpecifies how to handle detected number columns. DynamoDB returns number values with a total precision of 38.
OfflineUse offline mode to get the data from the cache instead of the live source.
OtherThese hidden properties are used only in specific use cases.
PagesizeThe maximum number of results to return per page from Amazon DynamoDB.
Pool Idle TimeoutThe allowed idle time for a connection before it is closed.
Pool Max SizeThe maximum connections in the pool.
Pool Min SizeThe minimum number of connections in the pool.
Pool Wait TimeThe max seconds to wait for an available connection.
Proxy Auth SchemeThe authentication type to use to authenticate to the ProxyServer proxy.
Proxy Auto DetectThis indicates whether to use the system proxy settings or not. This takes precedence over other proxy settings, so you'll need to set ProxyAutoDetect to FALSE in order use custom proxy settings.
Proxy ExceptionsA semicolon separated list of destination hostnames or IPs that are exempt from connecting through the ProxyServer .
Proxy PasswordA password to be used to authenticate to the ProxyServer proxy.
Proxy PortThe TCP port the ProxyServer proxy is running on.
Proxy ServerThe hostname or IP address of a proxy to route HTTP traffic through.
Proxy SSL TypeThe SSL type to use when connecting to the ProxyServer proxy.
Proxy UserA user name to be used to authenticate to the ProxyServer proxy.
Pseudo ColumnsThis property indicates whether or not to include pseudo columns as columns to the table.
ReadonlyYou can use this property to enforce read-only access to Amazon DynamoDB from the provider.
Retry Wait TimeThe minimum number of milliseconds the provider will wait to retry a request.
Row Scan DepthThe maximum number of rows to scan to look for the columns available in a table.
RTKThe runtime key used for licensing.
Separator CharacterThe character or characters used to denote hierarchy.
SSL Server CertThe certificate to be accepted from the server when connecting using TLS/SSL.
Support Enhanced SQLThis property enhances SQL functionality beyond what can be supported through the API directly, by enabling in-memory client-side processing.
TablesThis property restricts the tables reported to a subset of the available tables. For example, Tables=TableA,TableB,TableC.
Temporary Token DurationThe amount of time (in seconds) a temporary token will last.
Thread CountThe number of threads to use when selecting data via a parallel scan. Setting ThreadCount to 1 will disable parallel scans.
TimeoutThe value in seconds until the timeout error is thrown, canceling the operation.
Type Detection SchemeDetermines how to determine the data type of columns.
URLThe URL to use when submitting requests. This should not normally need to be set.
Use Connection PoolingThis property enables connection pooling.
Use Consistent ReadsWhether to alyways use Consistent Reads or not when querying DynamoDb.
Use Simple NamesBoolean determining if simple names should be used for tables and columns.
VerbosityThe verbosity level that determines the amount of detail included in the log file.
ViewsRestricts the views reported to a subset of the available tables. For example, Views=ViewA,ViewB,ViewC.
