When starting the program, the following error will be reported：

clojure.lang.ExceptionInfo: Conflicting data-reader mapping {:url #object[java.net.URL 0x2b4c1d96 "jar:file:/C:/Users/xlawin/.m2/repository/com/xtdb/xtdb-api/2.0.0-SNAPSHOT/xtdb-api-2.0.0-SNAPSHOT.jar!/data_readers.clj"], :conflict xt/runtime-err, :mappings {xt/runtime-err #'xtdb.error/-runtime-err-reader, xt/interval-ym #'xtdb.serde/interval-ym-reader, xt/interval-mdn #'xtdb.serde/interval-mdn-reader, xt.tx/delete #'xtdb.serde/delete-op-reader, xt.tx/sql #'xtdb.serde/sql-op-reader, xt.tx/xtql #'xtdb.serde/xtql-op-reader, xt.tx/erase #'xtdb.serde/erase-op-reader, xt/interval-dt #'xtdb.serde/interval-dt-reader, xt/period-duration #'xtdb.serde/period-duration-reader, xt/tx-key #'xtdb.serde/tx-key-read-fn, xt.tx/put #'xtdb.serde/put-op-reader, xt/illegal-arg #'xtdb.error/-iae-reader, xt.arrow/type #'xtdb.types/->arrow-type, xt.tx/call #'xtdb.serde/call-op-reader, xt/clj-form #'xtdb.api/->ClojureForm}}

I found that when the dependency is replaced with the com.xtdb/xtdb-api library (like https://github.com/xtdb/sakila-playground), it works fine.

;; for testing only - run XTDB as a server for production(!)
;; com.xtdb.labs/xtdb-core {:mvn/version "2.0.0-SNAPSHOT"}
;; com.xtdb.labs/xtdb-http-server {:mvn/version "2.0.0-SNAPSHOT"}
;; com.xtdb.labs/xtdb-pgwire-server {:mvn/version "2.0.0-SNAPSHOT"}

;; XTDB API and http client
;; com.xtdb.labs/xtdb-api {:mvn/version "2.0.0-SNAPSHOT"}
;; com.xtdb.labs/xtdb-http-client-clj {:mvn/version "2.0.0-SNAPSHOT"}

;; works fine

Contenders:

• TMDB via https://github.com/xtdb/xtdb-kaggle
  pros: interesting time dimension, can discuss corrections and backfill of financial data
  cons: not a realistic application example, no valid time changes OOTB
• https://www.jooq.org/sakila - superset of TMDB with rental etc.
• https://github.com/FiV0/xtdb-chinook (no times, could be good intro though as the schema is tiny)
• https://docs.microsoft.com/en-us/sql/relational-databases/tables/temporal-tables?view=sql-server-ver16#samples (system time only), probably not suitably licensed but may offer inspiration
