What's new in Spatiotemporal searching for Informix, Version 12.10

Spatiotemporal searching is improved in the following ways:

• You can now track stationary objects and objects that temporarily do not have a signal.
• You can speed the indexing of new data by running multiple Scheduler tasks in parallel. Alternatively, you can configure time series loader functions to trigger spatiotemporal indexing as time series data is saved to disk.
• You can now configure storage spaces and extents size for spatiotemporal data and each of the spatiotemporal indexes.
• You no longer have any restrictions on the configuration of the time series table or the number of rows. You can index spatiotemporal data in a tenant database. You location data can be in a BSON column within the TimeSeries subtype. Your time series data can be compressed or have a hertz frequency.
• Distance measurements now use a spherical calculation that is based on longitude and latitude coordinates instead of a Euclidean calculation that is based on the Cartesian system.

If you have spatiotemporal data and indexes from a previous release of Informix, you must drop your existing spatiotemporal tables and indexes and re-create them. All spatiotemporal functions are renamed, however, applications that use the previous function names still run.
