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 Basic Tab.


AuthSchemeThe type of authentication to use when connecting to Couchbase.
UserThe Couchbase user account used to authenticate.
PasswordThe password used to authenticate the user.
CredentialsFileUse this property if you need to provide credentials for multiple users or buckets. This file takes priority over other forms of authentication.
ServerThe address of the Couchbase server or servers to which you are connecting.
CouchbaseServiceDetermines the Couchbase service to connect to. Default is N1QL. Available options are N1QL and Analytics.
ConnectionModeDetermines how to connect to the Couchbase server. Must be either Direct or Cloud.
DNSServerDetermines what DNS server to use when retrieving Couchbase Capella information.
N1QLPortThe port for connecting to the Couchbase N1QL Endpoint.
AnalyticsPortThe port for connecting to the Couchbase Analytics Endpoint.
WebConsolePortThe port for connecting to the Couchbase Web Console.


SSLClientCertThe TLS/SSL client certificate store for SSL Client Authentication (2-way SSL).
SSLClientCertTypeThe type of key store containing the TLS/SSL client certificate.
SSLClientCertPasswordThe password for the TLS/SSL client certificate.
SSLClientCertSubjectThe subject of the TLS/SSL client certificate.
UseSSLWhether to negotiate TLS/SSL when connecting to the Couchbase server.
SSLServerCertThe certificate to be accepted from the server when connecting using TLS/SSL.


FirewallTypeThe protocol used by a proxy-based firewall.
FirewallServerThe name or IP address of a proxy-based firewall.
FirewallPortThe TCP port for a proxy-based firewall.
FirewallUserThe user name to use to authenticate with a proxy-based firewall.
FirewallPasswordA password used to authenticate to a proxy-based firewall.


ProxyAutoDetectThis 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.
ProxyServerThe hostname or IP address of a proxy to route HTTP traffic through.
ProxyPortThe TCP port the ProxyServer proxy is running on.
ProxyAuthSchemeThe authentication type to use to authenticate to the ProxyServer proxy.
ProxyUserA user name to be used to authenticate to the ProxyServer proxy.
ProxyPasswordA password to be used to authenticate to the ProxyServer proxy.
ProxySSLTypeThe SSL type to use when connecting to the ProxyServer proxy.
ProxyExceptionsA semicolon separated list of destination hostnames or IPs that are exempt from connecting through the ProxyServer .


LogModulesCore modules to be included in the log file.


LocationA path to the directory that contains the schema files defining tables, views, and stored procedures.
DataverseWhich Analytics dataverse to scan when discovering tables.
TypeDetectionSchemeDetermines how the provider builds tables and columns from the buckets found in Couchbase.
InferNumSampleValuesThe maximum number of values for every field to scan before determining its data type. Applies to Automatic Schema Discovery when TypeDetectionScheme is set to INFER.
InferSampleSizeThe maximum number of documents to scan for the columns available in the bucket. Applies to Automatic Schema Discovery when TypeDetectionScheme is set to INFER.
InferSimilarityMetricSpecifies the similarity degree where different schemas will be considered to be the same flavor. Applies to Automatic Schema Discovery when TypeDetectionScheme is set to INFER.
FlexibleSchemasWhether the provider allows queries to use columns that it has not discovered.
ExposeTTLSpecifies whether document TTL information should be exposed.
NumericStringsWhether to allow string values to be treated as numbers.
IgnoreChildAggregatesWhether the provider exposes aggregate columns that are also available as child tables. Ignored if TableSupport is not set to Full.
TableSupportHow much effort the provider will put into discovering tables on the Couchbase server.
NewChildJoinsModeDetermines the kind of child table model the provider exposes.


AllowJSONParametersAllows raw JSON to be used in parameters when QueryPassthrough is enabled.
ChildSeparatorThe character or characters used to denote child tables.
CreateTableRamQuotaThe default RAM quota, in megabytes, to use when inserting buckets via the CREATE TABLE syntax.
DataverseSeparatorThe character or characters used to denote Analytics dataverses and scopes/collections.
FlattenArraysThe number of elements to expose as columns from nested arrays. Ignored if IgnoreChildAggregates is enabled.
FlattenObjectsSet FlattenObjects to true to flatten object properties into columns of their own. Otherwise, objects nested in arrays are returned as strings of JSON.
FlavorSeparatorThe character or characters used to denote flavors.
GenerateSchemaFilesIndicates the user preference as to when schemas should be generated and saved.
InsertNullValuesDetermines whether an INSERT should include fields that have NULL values.
MaxRowsLimits 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.
OtherThese hidden properties are used only in specific use cases.
PagesizeThe maximum number of results to return per page from Couchbase.
PeriodsSeparatorThe character or characters used to denote hierarchy.
QueryExecutionTimeoutThis sets the server-side timeout for the query, which governs how long Couchbase will execute the query before returning a timeout error.
ReadonlyYou can use this property to enforce read-only access to Couchbase from the provider.
RowScanDepthThe maximum number of rows to scan to look for the columns available in a table.
StrictComparisonAdjusts how precisely to translate filters on SQL input queries into Couchbase queries. This can be set to a comma-separated list of values, where each value can be one of: date, number, boolean, or string.
TimeoutThe value in seconds until the timeout error is thrown, canceling the operation.
TransactionDurabilitySpecifies how a document must be stored for a transaction to succeed. Specifies whether to use N1QL transactions when executing queries.
TransactionTimeoutThis sets the amount of time a transaction may execute before it is timed out by Couchbase.
UpdateNullValuesDetermines whether an UPDATE writes NULL values as NULL, or removes them.
UseCollectionsForDDLWhether to assume that CREATE TABLE statements use collections instead of flavors. Only takes effect when connecting to Couchbase v7+ and GenerateSchemaFiles is set to OnCreate.
UserDefinedViewsA filepath pointing to the JSON configuration file containing your custom views.
UseTransactionsSpecifies whether to use N1QL transactions when executing queries.
ValidateJSONParametersAllows the provider to validate that string parameters are valid JSON before sending the query to Couchbase.
