Technologies are described for routing structured query language (SQL) statements to elastic compute nodes (ECNs) using workload classes within a distributed database environment. The elastic compute nodes do not store persistent database tables. For example, a SQL statement can be received for execution within the distributed database environment. A workload class can be identified that matches properties of the SQL statement. Based on the workload class, a routing location hint can be obtained that identifies a set of elastic compute nodes. The SQL statement can then be routed to one of the identified elastic compute nodes for execution. Execution of the SQL statement at the elastic compute node can involve retrieving database data from other nodes which store persistent database tables.

Disclosed herein are embodiments for performing multi-version concurrency control (MVCC) in non-volatile memory. An embodiment operates by determining that an event occurred, wherein one or more write transactions to one or more records of a multi-version database that were pending prior to the event did not commit. The one or more write transactions are identified based on a commit value that was stored in the non- volatile memory prior to the event. A particular one of the identified uncommitted write transactions is selected. From the multi-version database, a first version of a record corresponding to the selected uncommitted write transaction that was not committed, and an earlier version of the record that was committed prior to the event are identified. A visibility of the record is set to indicate that the earlier version of the record is visible and the first version of the record is not visible.

A determination is made as to whether the query is a read query or a write query. In response to determining that the query is a read query, the query is processed using the union view. In response to determining that the query is a write query, the query is modified to use the first writable table and the query is processed using the writable table.
