Yes, it is planned for early next year.
Thank you for your confirmation. Did you see any environment variables start with 'VBR'?$ env | sort | grep -e '^VBR'
vbr_worker.py file has to be located in /opt/vertica/bin directory. Does '/appdefender/vertica/bin/vbr_worker.py' file exist on all nodes? Do you know which tool has moved the files to /appdefender directory and when? Do you know how to move the files to the original directories?
$ env | sort | grep -e '^VBR'
This is the message that Vertica receives the 'clusterstatus' command from the client. As this is the product specification and is helpful to know Vertica receives this command from the unexcepted machines, we cannot make Vertica stop to generate this message. I think 192.168.183.61 machine is for MC. Please ignore this FATAL message on your monitoring tool.
@HyeontaeJu is probably refering to the MERGE SQL statement (i.e. MERGE INTO...)
Merge out and Merge into are totally different and has no relation at all.
Remember Vertica creates new container per table per load. Merge out is to consolidate multiple containers into a single container for better read performance of database.
Merge into is a SQL statement that performs update (if data exists on target table) and insert (if data not exists on target table) at the same time to consolidate data from SQL level. You can refer details for merge into statement from the URL Jim has posted earlier.
This works too...
dbadmin=> SELECT REGEXP_LIKE(c, '[0-9]+'), REGEXP_LIKE(c, '[0-9]+'), REGEXP_LIKE(c, '[0-9]+') FROM a;
REGEXP_LIKE | REGEXP_LIKE | REGEXP_LIKE
f | f | t
Try settings export addresses as in this doc: https://www.vertica.com/kb/Configuring-Network-to-Import-and-Export-Data/Content/BestPractices/Configuring-Network-to-Import-and-Export-Data.htm.
Or, if you want to use ipmap, try something like the following in Opts:
"ipmap" -> "192.168.61.77->172.16.61.77, 192.168.61.78->172.16.61.78, 192.168.61.79->172.16.61.79"
Where 192.168.61.77, 192.168.61.78, 192.168.61.79 are my private IPs and 172.16.61.77, 172.16.61.78, 172.16.61.79 are my public IPs.
192.168.61.77, 192.168.61.78, 192.168.61.79
172.16.61.77, 172.16.61.78, 172.16.61.79
You can only create projections on tables, but you can tune projections for joins!
Another option is a Vertica Flattened table where you eliminate the joins altogether at query time.
Please consider using Ctrl Char as a delimiter and as a record separator,
When a printable delimiter character or \n is part of the data itself.
For example, here we use \001 (CTRL-A) as field separator
and \002 (CTRL-B) as record separator
Export command example:
vsql -F $'\001' -R $'\002' -P null='REALNULL' -AXtnqc \
"select * from schema_name.table_name limit 100" > \
Import command example, for a COPY command one can use to load data exported as shown above:
record terminator E'\002'
abort on error;
Note that you also get this error when calling CURRVAL but not first calling NEXTVAL:
dbadmin=> CREATE SEQUENCE s;
dbadmin=> SELECT s.CURRVAL;
ERROR 4700: Sequence s has not been accessed in the session
