41.2.7. Schema
Property | Description |
Location | A path to the directory that contains the schema files defining tables, views, and stored procedures. |
BrowsableSchemas | This property restricts the schemas reported to a subset of the available schemas. For example, BrowsableSchemas=SchemaA,SchemaB,SchemaC. |
Tables | This property restricts the tables reported to a subset of the available tables. For example, Tables=TableA,TableB,TableC. |
Views | Restricts the views reported to a subset of the available tables. For example, Views=ViewA,ViewB,ViewC. |
41.2.8. Caching
Property | Description |
AutoCache | Automatically caches the results of SELECT queries into a cache database specified by either CacheLocation or both of CacheConnection and CacheProvider . |
CacheDriver | The database driver to be used to cache data. |
CacheConnection | The 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. |
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. |
CacheMetadata | This property determines whether or not to cache the table metadata to a file store. |
41.2.9. Miscellaneous
Property | Description |
BatchSize | The maximum size of each batch operation to submit. |
ConnectionLifeTime | The maximum lifetime of a connection in seconds. Once the time has elapsed, the connection object is disposed. |
ConnectOnOpen | This property species whether to connect to the Redis when the connection is opened. |
IgnoreTypeErrors | Removes support for the specified data types and ignores casting exceptions for those types. |
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. |
ParallelMode | This option sets whether the provider should use multiple connections when connecting to Redis. |
PoolIdleTimeout | The allowed idle time for a connection before it is closed. |

PoolWaitTime | The max seconds to wait for an available connection. |
PseudoColumns | This property indicates whether or not to include pseudo columns as columns to the table. |
QueryTimeout | The timeout in seconds for which the provider will wait for the query response. The default value is -1, which indicates the provider should never time out. |
Readonly | You can use this property to enforce read-only access to Redis from the provider. |
RowScanDepth | The maximum number of rows to scan to look for the columns available in a table. |
RTK | The runtime key used for licensing. |
