My first tests with QuestDB on 10 years of home automation data (1.4 billion rows) are promising.
👉 Fast ingestion of parquet files (~1 hour on an old Intel NUC i5)
I have stored my data in parquet files, one per month, and imported it with a simple Python script. The import on my really old Intel NUC i5 took only about one hour. I’ve never been able to do this so quickly with any other database.
🤔 Btw.: I think storing data in #parquet files, or any other open table format, like Apache Iceberg, is one of the best choices to keep data. Because it’s independent of a database engine.
👉 Familiar SQL syntax. I experienced that QuestDB has a powerful SQL engine. I converted some Postgres SQL statements to QuestDB without big issues or changes. And I love SQL 💚
👉 Great query response times – see image. Not a representative query, but still impressive speed.
👉 By using ZFS with compression the used disk space can be reduced to a good value.
Do you want to log your OPCUA data to QuestDB? I have added this option to the automation-gateway.com seven days ago.
