Used for fixed authentication, setting this ( Optional) A session token for temporary credentials, such asĬredentials obtained from SSO. The secret key of the principal to authenticate with for the token Used for fixed authentication, setting this property The access key of the principal to authenticate with for the token The name of the AWS region in which the Redshift instance is deployed. This table describes the configuration properties for IAMĪuthentication: IAM configuration properties # To manually collect statistics for a table, execute the following statement in The statistics are collected by Redshift and retrieved by the connector.ĪNALYZE may be run automatically depending on your Redshift configuration. The Redshift connector supports table and column statistics to improve query processing performance based on Query performance and is only recommended for testing and troubleshooting. Set toĪUTOMATIC to enable cost-based join pushdown, or EAGER to Strategy used to evaluate whether join operations are pushed down. Session property is join_pushdown_enabled. The following table describes catalog configuration properties for Operation pushdown does not occur to avoid a potential decrease in query Note that if no table statistics are available, join Operations if the available Table statistics suggest that doing so When cost-based join pushdown is enabled, the connector only pushes down join The connector supports cost-based Join pushdown to make intelligentĭecisions about whether to push down a join operation to the data source. The connector supports pushdown for a number of operations: The connector includes a number of performance improvements, detailed in the The connector supports all of the SQL statements listed in the Redshift
The time is rounded to the nearest microsecond before being inserted. When writing data with higher precision from SEP to Redshift, Redshift’s TIME and TIMESTAMP types only support microsecond precision This connector supports writing the following SEP types and performsĬonversion to Redshift types with the detailed mappings as shown in theįollowing table. Redshift’s TEXT is equivalent to VARCHAR(256). Redshift’s BPCHAR is equivalent to CHAR(256). This connector supports reading the following Redshift types and performsĬonversion to SEP types with the detailed mappings as shown in the following Starburst SingleStore (MemSQL) connectorĬonnector.name = redshift connection-url = jdbc:redshift://:5439/database connection-user = redshift_username connection-password = redshift_password Type mapping #īecause SEP and Redshift each support types that the other does not, thisĬonnector modifies some types when reading or writing data.Starburst Redshift connector Starburst Redshift connector Contents.
