PostGIS vs TileDB

PostGIS: The standard spatial extension for PostgreSQL: geometry, geography, rasters and topology in SQL. TileDB: Embeddable multidimensional array storage engine for dense and sparse data on object storage.

key differences

PostGIS is primarily a spatial database; TileDB is array / scientific.
Licensing: PostGIS is open source (copyleft) (GNU GPL v2.0); TileDB is open source (permissive) (MIT License).
TileDB is built for larger datasets (≤ 1 PB) than PostGIS (≤ 10 TB).
Horizontal scaling is addon in PostGIS and manual in TileDB.
Transactions: PostGIS offers full ACID; TileDB offers limited.
Only PostGIS has transactions, joins, secondary indexes, geospatial, json.
Only TileDB has vector search, columnar storage, compression, encryption at rest, time travel.
TileDB can run embedded in your application process.
