![]() ![]() A "base" table, which contains the same data as the real table except for the. ![]() The connector creates the following virtual tables: If a table contains any collection columns, when the table is queried for the first time, Storage of the data in its denormalized form in Cassandra. By re-normalizing the dataĬontained within collections (sets, lists, and maps) into virtual tables, the connector allows users to directly interact with the data but leave the However, Analyticsĭoes not support accessing this type of data. Sets, lists, and maps, transactions can be simplified. By taking advantage of nested data structures such as One advantage of the Apache Cassandra design is the ability to store data that isĭenormalized into fewer tables. The password for the private key file that is specified in the Client-side Private Key field. The full path to the file containing the private key used to verify the client. pem file containing the certificate for verifying the client. pem file containing the certificate for verifying the server. Specifies whether the driver mandates the host name of the server to match the host name in the SSL certificate. Otherwise, the driver connects to the Cassandra server using SSL but the client and server do not verify each other. Two-way Server and Client Verification - If the Enable Server Hostname Verification option is enabled, the client and the Cassandra server verify each other using SSL. One-way Server Verification - If the Enable Server Hostname Verification option is enabled, the client verifies the Cassandra server using SSL. Specifies how the driver uses SSL to connect to the Cassandra server. When the Enable Paging option is enabled, use this option to specify the maximum number of rows to display on each page. Specifies whether to split large result sets into pages. Specifies whether to use SQL_WVARCHAR for text and varchar types. If this option is enabled, all schemas, tables, and columns must be double quotation marks ("). Specifies whether the driver differentiates between capital and lower-case letters in schema, table, and column names. Specifies whether the driver must insert all NULL values as specified in INSERT statements. Specifies whether the driver must use a latency-awareness algorithm to distribute the load away from slower-performing nodes. Specifies whether to use a token-aware policy to improve load balancing and latency. The name of a virtual table consists of the name of the original table, then the separator, and then the name of the collection. The separator for naming a virtual table built from a collection. The default column length to report for ASCII, TEXT, and VARCHAR columns. The default column length to report for BLOB columns. Specifies the load balancing policy to be used. The specific Cassandra replica or the number of Cassandra replicas that must process a query for the query to be successful. If a query fails, then the driver executes the query in CQL. SQL with CQL Fallback - Uses SQL_WITH_CQL_FALLBACK_QUERY_MODE and executes all queries in SQL by default.CQL - Uses CQL_QUERY_MODE and executes all queries in CQL.SQL - Uses SQL_QUERY_MODE and executes all queries in SQL.Specifies the query mode to use when sending queries to Cassandra. The password corresponding to the user name provided. The user name to use to access the Cassandra server. The authentication mechanism to use to connect to Cassandra server. The default keyspace (schema) to connect to in Cassandra. The IP address or host name of the Cassandra server. Connection settings Basic settings Setting For help importing data from Cassandra, see Working with the Data Access window. Once the connection is established, the Data Access window opens to the Staging Area and you can begin importing data. In the future, you can reconnect to Cassandra from the saved connection. The connection for Cassandra is saved to the Existing Connections tab. You can accept the default Connection Name, or enter a new one. In the Data Connection Settings panel, enter the connection settings and at the bottom of the panel, click Save and Connect.You can filter the list of available connectors by entering a search string in the Filter connections box. ![]()
