Licensing options for this format begin with FME Professional Edition.
The Amazon Aurora Non-Spatial plug-in enables FME to read and write attribute data stored in an Amazon Aurora database. There are two versions of this reader and writer:
- Amazon Aurora Non-Spatial, which is an attribute-only version that ignores geometry.
- Amazon Aurora Spatial (MYSQL_AURORA_SPATIAL) Reader/Writer, which includes the spatial extension and supports geometry features, and
This reader/writer communicates directly with the MySQL C API interface for maximum throughput.
This chapter assumes familiarity with Amazon Aurora, the table types, column types, available server daemons, indexing mechanisms and connection parameters.
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.
Tables schemas must be defined in the FME workspace before they can be read.
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.
Please note that Amazon Aurora functionality that only exists in the Amazon Aurora road map and not in practice (such as server side cursors and views) are not currently integrated into this reader.
The Amazon Aurora Non-Spatial writer stores both geometry and attributes into an Amazon Aurora database, and has 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, no indexes are created. 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.
