Use this property if you need to provide credentials for multiple users or buckets. This file takes priority over other forms of authentication.
Server
The address of the Couchbase server or servers to which you are connecting.

Determines the Couchbase service to connect to. Default is N1QL. Available options are N1QL and Analytics.
ConnectionMode
Determines how to connect to the Couchbase server. Must be either Direct or Cloud.
DNSServer
Determines what DNS server to use when retrieving Couchbase Cloud information.
N1QLPort
The port for connecting to the Couchbase N1QL Endpoint.
AnalyticsPort
The port for connecting to the Couchbase Analytics Endpoint.
WebConsolePort
The port for connecting to the Couchbase Web Console.
SSL
Property
Description
SSLClientCert
The TLS/SSL client certificate store for SSL Client Authentication (2-way SSL).
SSLClientCertType
The type of key store containing the TLS/SSL client certificate.
SSLClientCertPassword
The password for the TLS/SSL client certificate.
SSLClientCertSubject
The subject of the TLS/SSL client certificate.
UseSSL
Whether to negotiate TLS/SSL when connecting to the Couchbase server.
SSLServerCert
The certificate to be accepted from the server when connecting using TLS/SSL.
Firewall
Property
Description
FirewallType
The protocol used by a proxy-based firewall.
FirewallServer
The name or IP address of a proxy-based firewall.
FirewallPort
The TCP port for a proxy-based firewall.
FirewallUser
The user name to use to authenticate with a proxy-based firewall.
FirewallPassword
A password used to authenticate to a proxy-based firewall.
Proxy
Property
Description
ProxyAutoDetect
This 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.
ProxyServer
The hostname or IP address of a proxy to route HTTP traffic through.
ProxyPort
The TCP port the ProxyServer proxy is running on.
ProxyAuthScheme
The authentication type to use to authenticate to the ProxyServer proxy.
ProxyUser
A user name to be used to authenticate to the ProxyServer proxy.
ProxyPassword
A password to be used to authenticate to the ProxyServer proxy.
ProxySSLType
The SSL type to use when connecting to the ProxyServer proxy.
ProxyExceptions
A semicolon separated list of destination hostnames or IPs that are exempt from connecting through the ProxyServer .
Logging
Property
Description
LogModules
Core modules to be included in the log file.
Schema
Property
Description
Location
A path to the directory that contains the schema files defining tables, views, and stored procedures.
Dataverse
Which Analytics dataverse to scan when discovering tables.
TypeDetectionScheme
Determines how the provider builds tables and columns from the buckets found in Couchbase.
InferNumSampleValues
The 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.
InferSampleSize
The maximum number of documents to scan for the columns available in the bucket. Applies to Automatic Schema Discovery when TypeDetectionScheme is set to INFER.
InferSimilarityMetric
Specifies 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.
FlexibleSchemas
Whether the provider allows queries to use columns that it has not discovered.
ExposeTTL
Specifies whether document TTL information should be exposed.
NumericStrings
Whether to allow string values to be treated as numbers.
IgnoreChildAggregates
Whether the provider exposes aggregate columns that are also available as child tables. Ignored if TableSupport is not set to Full.
TableSupport
How much effort the provider will put into discovering tables on the Couchbase server.
NewChildJoinsMode
Determines the kind of child table model the provider exposes.
Miscellaneous
Property
Description
AllowJSONParameters
Allows raw JSON to be used in parameters when QueryPassthrough is enabled.
ChildSeparator
The character or characters used to denote child tables.
CreateTableRamQuota
The default RAM quota, in megabytes, to use when inserting buckets via the CREATE TABLE syntax.
DataverseSeparator
The character or characters used to denote Analytics dataverses and scopes/collections.
FlattenArrays
The number of elements to expose as columns from nested arrays. Ignored if IgnoreChildAggregates is enabled.
FlattenObjects
Set FlattenObjects to true to flatten object properties into columns of their own. Otherwise, objects nested in arrays are returned as strings of JSON.
FlavorSeparator
The character or characters used to denote flavors.
GenerateSchemaFiles
Indicates the user preference as to when schemas should be generated and saved.
InsertNullValues
Determines whether an INSERT should include fields that have NULL values.
MaxRows
Limits 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.
Other
These hidden properties are used only in specific use cases.
Pagesize
The maximum number of results to return per page from Couchbase.
PeriodsSeparator
The character or characters used to denote hierarchy.
QueryExecutionTimeout
This sets the server-side timeout for the query, which governs how long Couchbase will execute the query before returning a timeout error.
Readonly
You can use this property to enforce read-only access to Couchbase from the provider.
RowScanDepth
The maximum number of rows to scan to look for the columns available in a table.
StrictComparison
Adjusts 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.
Timeout
The value in seconds until the timeout error is thrown, canceling the operation.
TransactionDurability
Specifies how a document must be stored for a transaction to succeed. Specifies whether to use N1QL transactions when executing queries.
TransactionTimeout
This sets the amount of time a transaction may execute before it is timed out by Couchbase.
UpdateNullValues
Determines whether an UPDATE writes NULL values as NULL, or removes them.
UseCollectionsForDDL
Whether 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.
UseTransactions
Specifies whether to use N1QL transactions when executing queries.
ValidateJSONParameters
Allows the provider to validate that string parameters are valid JSON before sending the query to Couchbase.
