I used Apache Drill to query json line log files stored in Azure Blob. It is very easy to configure and run it. I used in embedded mode for not so big queries and some visualisation in Apache Superset. It worked really well. I created some views in parquet to speed it up.

Be aware, there is no such thing as schemaless, Drill is schema on-read and if your files contain changing schemas, it is painful to workaround all the errors you face. JSON is too ambiguous when it comes to types.

If the “Director of Customer Solutions” for the company selling presto feels the need to write a blog post declaring Apache drill dead, that might be a sign that it is actually competing pretty well with presto.

Well, I was seeking a technical comparison.

Presto has been rebranded to Trino. Trino supports MATCH_RECOGNIZE from the SQL:2016 standard which is pretty cool. The only database engine that does that so far is Oracle.
