| 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. |

| CacheLocation | Specifies the path to the cache when caching to a file. |
| CacheTolerance | The tolerance for stale data in the cache specified in seconds when using AutoCache . |
| Offline | Use offline mode to get the data from the cache instead of the live source. |

| 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. |
