redshift session details

Temp tables are bound per session (connect), therefor cannot be shared across sessions. Amazon Redshift retains a great deal of metadata about the various databases within a cluster and finding a list of tables is no exception to this rule. This is a very simple library that gets credentials of a cluster via redshift.GetClusterCredentials API call and then makes a connection to the cluster and runs the provided SQL statements, once done it will close the connection and return the results. If a match is found in the result cache, Amazon Redshift uses the cached results and doesn’t execute the query. how can I set autocommit in SQL session, is there something in Redshift like.
