Caching:

Performance tips:
Partitioning on VARCHAR columns (not high cardinality) that are included in WHERE of SELECTs
ANALYZE to gather statistics: https://prestosql.io/docs/current/optimizer/statistics.html
Compressed ORC/Parquet files with size between 32MB-1GB and the columns inside the files sorted so min/max ranges don't overlap for reduced network IO and better predicate pushdown (https://www.slideshare.net/databricks/the-parquet-format-and-performance-optimization-opportunities)
There are no Primary Keys/Foreign Keys/Indexes
https://aws.amazon.com/blogs/big-data/top-10-performance-tuning-tips-for-amazon-athena/
High CPU important for parallelism/concurrency
High Memory important for joins/group by/distinct
task.max-worker-threads
task.concurrency

Security:
LDAP/Kerberos/JWT/Cert
TLS
Apache Ranger for column/table/schema/catalog level authorisation, column masking and row level filtering fine grained access

All view sql:
from_utf8(from_base64(substr(view_original_text,17,length(view_original_text) - 19))) view_sql

Very useful feature is joining between data from any of the connectors.
Disclaimer: while Hive sources are suitable for data of large size (ie Petabytes), JDBC sources are only performant on small tables. For example:
you have a 8 billion row txns table that is indexed/partitioned in Oracle.
Below query takes 38 seconds run in Oracle directly but 70 minutes when run in Presto -->

select custid, count(1) numtxns from oracle.txns
where txnmonth in (to_date('202002','YYYYMM'),to_date('201902','YYYYMM'))
group by custid
having count(1) > 4

DISTINCT pushdown #4324
