## Table schema design

When you create a table in Phoenix, that table is stored in a HBase table. The HBase table contains groups of columns (column families) that are accessed together. A row in the Phoenix table is a row in the HBase table, where each row consists of versioned cells associated with one or more columns. Logically, a single HBase row is a collection of key-value pairs, each having the same rowkey value. That is, each key-value pair has a rowkey attribute, and the value of that rowkey attribute is the same for a particular row.

The schema design of a Phoenix table includes the primary key design, column family design, individual column design, and how the data is partitioned.

### Primary key design
2121

22-
The primary key defined on a table in Phoenix determines how data is stored within the rowkey of the underlying HBase table. In HBase, the only way to access a particular row is with the rowkey. In addition, data stored in a HBase table is sorted by the rowkey. Phoenix builds the rowkey value by concatenating the values of each of the columns in the row, in the order they're defined in the primary key.

When you have multiple indexes defined and then query a table, Phoenix automatically selects the best index for the query. The primary index is created automatically based on the primary keys you select.

After you complete the quickstart, you may want to delete the cluster. With HDInsight, your data is stored in Azure Storage, so you can safely delete a cluster when it is not in use.

HDInsight cluster produces various log files. For example, Apache Hadoop and related services, such as Apache Spark, produce detailed job execution logs. Log file management is part of maintaining a healthy HDInsight cluster. There can also be regulatory requirements for log archiving. Due to the number and size of log files, optimizing log storage and archiving helps with service cost management.
