ADO.NET Provider for Apache HBase

Build 24.0.9175

Miscellaneous

This section provides a complete list of the Miscellaneous properties you can configure in the connection string for this provider.


PropertyDescription
BatchSizeSpecifies the maximum number of rows included in each batch operation. Set to 0 to submit the entire batch as a single request.
ColumnEncodingThe Encoding used for the column values. Accepted entries are None, UTF8, and BASE64. None is the default.
ConnectionLifeTimeSpecifies the maximum lifetime of a connection in seconds. When the specified time elapses, the provider closes the connection. Set to 0 or leave empty for no time limit.
DatetimeFormatThe format used when inserting datetime values into the database.
ExposeColumnTimestampSpecifies whether to expose the cell timestamp as a separate column when executing the SELECT Statement.
IncludeDisabledTablesSpecifies whether to retrieve disabled tables.
MaxRowsSpecifies the maximum rows returned for queries without aggregation or GROUP BY.
OtherSpecifies additional hidden properties for specific use cases. These are not required for typical provider functionality. Use a semicolon-separated list to define multiple properties.
PagesizeSpecifies the maximum number of results to return from Apache HBase, per page. This setting overrides the default page size set by the datasource, which is optimized for most use cases.
PoolIdleTimeoutSpecifies the maximum idle time, in seconds, that a connection can remain in the pool before being closed.
PoolMaxSizeSpecifies the maximum number of connections allowed in the connection pool. The default value is 100. Set to 0 or a negative value to disable pooling.
PoolMinSizeSpecifies the minimum number of connections maintained in the connection pool. The default value is 1.
PoolWaitTimeSpecifies the maximum number of seconds a connection request waits for an available connection in the pool. If the wait exceeds this time, an error is returned. The default is 60 seconds.
PseudoColumnsSpecifies the pseudocolumns to expose as table columns. Use the format 'TableName=ColumnName;TableName=ColumnName'. The default is an empty string, which disables this property.
ReadonlyToggles read-only access to Apache HBase from the provider.
ResetTableMetadataOnDeleteSpecifies whether to reset the cache table after executing the DELETE Statement.
RetrieveSelectedColumnsOnlySpecifies whether to retrieve selected columns only when executing a SELECT statement.
RowScanDepthThe maximum number of rows to scan to look for the columns available in a table.
RTKSpecifies the runtime key for licensing the provider. If unset or invalid, the provider defaults to the standard licensing method. Use this property only in environments where the standard licensing method is unsupported or requires a runtime key.
ScannerCachingSpecify a scanner cache that will be filled before the Scan result is returned, setting setCaching to the number of rows to cache before returning the result. By default, the caching setting on the table is used. The goal is to balance IO and network load.
TimeoutSpecifies the maximum time, in seconds, that the provider waits for a server response before throwing a timeout error. The default is 60 seconds. Set to 0 to disable the timeout.
TypeDetectionSchemeDetermines how to determine the data type of columns.
UseConnectionPoolingEnables the connection pooling feature, which allows the provider to reuse existing connections instead of creating new ones for each request.
UserDefinedViewsSpecifies a filepath to a JSON configuration file defining custom views. The provider automatically detects and uses the views specified in this file.
UseSQLFilteringSpecifies whether to use the ScannerFilter when executing the SELECT Statement.
