Amazon Aurora Spatial (MYSQL_AURORA_SPATIAL) Reader/Writer

Licensing options for this format begin with FME Desktop Professional Edition.

This format is based on the MariaDB/SkySQL (MySQL-compatible) Spatial Reader/Writer. It uses terminology specific to MySQL, since MariaDB is known to work well with MySQL Servers.


The Amazon Aurora Spatial plug-in enables FME to read and write attribute data stored in aN Amazon Aurora Spatial database. There are two versions of this reader and writer:

Reader Overview

FME considers a reader dataset to be a database containing a collection of relational tables, and a table to be an FME feature type with each row corresponding to at least one FME feature. In the case of geometry collections, a single row may become more than one FME feature.

Tables schemas must be defined in the FME workspace before they can be read and can consist of both geometric and primary column types, however, only one geometry column is read per table while others are discarded.

Arbitrary WHERE clauses and joins are fully supported, as well as an entire arbitrary SQL SELECT statement. The basic reading process involves opening a connection to the database, querying metadata, and querying data. The data is read by submitting SQL queries and parsing the returned result sets.

If null geometries are read, they are treated as non-geometry features and the attributes are preserved.

Writer Overview

The Amazon Aurora Spatial writer module stores both geometry and attributes into an Amazon Aurora database. The writer provides the following capabilities:

  • Transaction Support: The writer provides transaction support that eases the data loading process. Occasionally, a data load operation terminates prematurely due to data difficulties. The transaction support provides a mechanism for reloading corrected data without data loss or duplication. Performance can also be improved by reducing transactional overhead for multiple small queries such as inserts.
  • Index Creation: The writer can set up and populate indexes as part of the loading process. By default, a spatial R-Tree index is created on the primary geometry column of a table and not on any other columns. Additional columns can be individually indexed. Composite column indexes are not supported at this time.
  • Insert Binding: By default, the writer uses prepared statements and query parameter binding ensure speedy data loading.
