Indexing of tables in dataiku

My dataiku recipes are taking too long to run because of the absence of indexes in the parent datasets. How do i add indexing in the output data so that the next recipe in the flow can take advantage of the indexing. I need help urgently. Thanks in advance

    Hi akuma,

    Should you need indexes on your tables, go under the dataset in question and follow these steps:

    Go to Settings > Advanced. There you will find pre and post write statements. As an example in the pre-write statement you could drop the index and post-write create it again. This needs to follow the specific SQL syntax of your database.

    So for postgres it would look like:

    Pre-write statements:

    DROP INDEX IF EXISTS some_index;

    Post-write statements:

    CREATE INDEX some_index ON "${projectKey}_table_name"(column);
