  README describes a batteries-included lakehouse platform with no paid tier, enterprise edition or license-key-gated build beside the Apache-2.0 framework.

LakeSoul is consumed as a table format through Spark, Flink, Presto, Ray, Daft and PyArrow rather than installed as a single package, and no deployment count is published for any of them. That leaves GitHub stars as the only available adoption signal for this project.

LakeSoul is a distributed lakehouse with its own metadata management, transaction log and compaction service, ACID transactions and schema evolution, shared across six compute engines. Its file format supports vector retrieval only as a file-format capability, not as a ranking or embedding model running inside a serving path, which is what Vespa provides and what keeps LakeSoul one step below it.
