- 73. Other Cloud Data Stores: Cloud Databases … to name a few
- 75. ● Start publishing now! ● Keep the processing close to the data ● Minimize traffic footprint - select just what you need ● Leverage data side filtering, microservices, lazy evaluation ● Metadata: enrich and update ● Optimization strategy: transactions volume vs data volume, response time requirements ● Test! Especially your core usage scenarios Integration Strategies Key limitations & Integration Strategies
- 76. Considerations ● Heavier preprocessing, larger size required to structure and store data for optimized read ● Updates are a challenge - automation helps ● FME’s implementation based on third party libraries - collaboration for fixes, enhancements ● Newer cloud native formats: less data publicly available so far: COPC, ZARR ● Cloud optimized vector options - choice depend on use case: GeoParquet, FlatGeoBuf ● Supporting infrastructure: duckDB for Geoparquet etc Key limitations & Integration Strategies
- 78. 9 Conclusions
- 80. Lessons Learned ● Cloud native is all about making it easy to publish data without a server, optimizing responses to web data requests: read just what you need! ● No one size fits all: each format has its strengths and limitations ● STAC: steeper learning curve, collections within catalogs and vice versa, implementations vary; security ● COG, COPC: perhaps the most intuitive - 2d and 3d arrays are just easier to manage. STAC/COG most data ● Vector - still evolving: FlatGeoBuf more effective in its cloud native support but newer, less widely adopted. Geoparquet has more tooling but design and support needed to make effectively cloud native ● ZARR - powerful but complex - as a very new and niche format, support is still growing
- 81. Summary ● Cloud native is all about making it easy to publish data without a server, optimizing responses to web data requests: read just what you need! ● Safe’s strategy is to track and support emerging standards across a range of data types so FME users can stay ahead of evolving web technologies ● FME allows you to integrate between hybrid environments as needed ● Keep the processing close to the data ● Minimize traffic footprint - reader filtering ● Open standards enable community-wide adoption and access ● No one size fits all - know your key requirements & test!
