Parquet keeps the structure
Typed nested values survive in Parquet, while CSV encodes labels and thread fields into single cells.
Export Plain into Google Cloud Storage with Polytomic to archive support conversations or stage them for a query engine. Threads, messages and timeline events write as separate file sets, with nesting preserved or encoded depending on the format you pick.
Typed nested values survive in Parquet, while CSV encodes labels and thread fields into single cells.
Files land ready to register as external tables rather than needing a database in between.
Incremental reads mean a frequent export stays cheap instead of rewriting the full history each time.
