You can optimize your query performance by using OpenSearch indexes, such as a skipping index or a covering index. A _skipping index_ uses skip acceleration methods, such as partition, minimum and maximum values, and value sets, to ingest and create compact aggregate data structures. This makes them an economical option for direct querying scenarios. A _covering index_ ingests all or some of the data from the source into OpenSearch and makes it possible to use all OpenSearch Dashboards and plugin functionality.

Go to **OpenSearch Dashboards** > **Query Workbench** and select your Amazon S3 data source from the **Data sources** dropdown menu in the upper-left corner. -2. From the left-side navigation menu, select a database. An example using the `http_logs` database is shown in the following image. - - Query Workbench accelerate data UI - +2. From the left-side navigation menu, select a database. 3. View the results in the table and confirm that you have the desired data. 4. Create an OpenSearch index by following these steps: - 1. Select the **Accelerate data** button. A pop-up window appears. An example is shown in the following image. - - Accelerate data pop-up window - + 1. Select the **Accelerate data** button. A pop-up window appears. 2. Enter your details in **Select data fields**. In the **Database** field, select the desired acceleration index: **Skipping index** or **Covering index**. A _skipping index_ uses skip acceleration methods, such as partition, min/max, and value sets, to ingest data using compact aggregate data structures. This makes them an economical option for direct querying scenarios. A _covering index_ ingests all or some of the data from the source into OpenSearch and makes it possible to use all OpenSearch Dashboards and plugin functionality. - -5. Under **Index settings**, enter the information for your acceleration index. For information about naming, select **Help**. Note that an Amazon S3 table can only have one skipping index at a time.

Note that an Amazon S3 table can only have one skipping index at a time. ### Define skipping index settings -1. Under **Skipping index definition**, select the **Add fields** button to define the skipping index acceleration method and choose the fields you want to add. An example is shown in the following image. - - Skipping index add fields - +1. Under **Skipping index definition**, select the **Add fields** button to define the skipping index acceleration method and choose the fields you want to add. 2. Select the **Copy Query to Editor** button to apply your skipping index settings. -3. View the skipping index query details in the table pane and then select the **Run** button. Your index is added to the left-side navigation menu containing the list of your databases. An example is shown in the following image. - - Run a skippping or covering index UI +3. View the skipping index query details in the table pane and then select the **Run** button. Your index is added to the left-side navigation menu containing the list of your databases. ### Define covering index settings -1. Under **Index settings**, enter a valid index name. Note that each Amazon S3 table can have multiple covering indexes. An example is shown in the following image. - - Covering index settings - -2. Once you have added the index name, define the covering index fields by selecting `(add fields here)` under **Covering index definition**.
