Hi:
I think we can upgrade presto to 0.210 for CarbonData 1.5, 0.210 has fixed
an 'JDBC Driver' issue which is used frequently:
*Deallocate prepared statement when PreparedStatement is closed.
Previously, Connection became unusable after many prepared statements were
created.*

+1 for presto 0.207/0.208 upgradation.
As liang mentioned there are some memory issues related patches as well
there are some security fixes in 0.207 version
Hope the patches are present in presto 0.208 version also.
Thanks,
Sujith

Hi
Just i checked 0.207 and 0.208, there are fixed many memory issues, so
propose to upgrade to 0.208 for Apache CarbonData 1.5.0 integration.

Hi Dev,
Yes, we should definitely go for the 0.206 upgrade for Presto as we are now
using the dictionary_aggregation feature for optimization. The other bug
fixes are also important for carbondata integration.
However, they have changed the connector interface as well, so we might
need to change
Hi Dev
The presto community already released 0.206 last week (refer the detail at
https://prestodb.io/docs/current/release/release-0.206.html), this release
fixed many issues, so propose Apache CarbonData community to upgrade to the
latest presto version for carbondata integration.
please
