Clone API snoop database

• Create local postgres database: sudo -u postgres psql: create database hh;.
• Initialize database structure: sudo -u postgres psql hh < structure.sql.
• Dump api_operations table data into a local TSV file: psql -h apisnoop-db-host -U apisnoop-db-user hh -tAc "\copy (select * from api_operations) to '/tmp/api_operations.tsv'".
• Dump audit_events table data into a local TSV file: psql -h apisnoop-db-host -U apisnoop-db-user hh -tAc "\copy (select * from audit_events) to '/tmp/audit_events.tsv'".
• Restore api_operations table data locally: sudo -u postgres psql hh -tAc "\copy api_operations from '/tmp/api_operations.tsv'".
• Restore audit_events table data locally: sudo -u postgres psql hh -tAc "\copy audit_events from '/tmp/audit_events.tsv'".

Update OpID via Regexp

Note that all mass update script only update records with null on opid, so they can be called iteratively.

• Run: make, time sudo -u postgres ./rmatch. That will update op_id column on audit_events table.
• You can use CONN='....' to specify your own custom connect string, see example connect strings in lib.go.
• You can use ANALYSIS=1 to get information about how many records had 0, 1, 2, ... matches.
• You can use DBG=1 to get a lot more verbose output.

Restore into the original database

• Generate SQL file to be run on the original database: make, time sudo -u postgres ./gensql > update.sql.
• Run script on the original database: psql -h apisnoop-db-host -U apisnoop-db-user hh < update.sql.

You can also generate TSV dumps from your local databae and restore them on the remote, but the above solution is faster and better

• Dump api_operations table data into a local TSV file: sudo -u postgres psql hh -tAc "\copy (select * from api_operations) to '/tmp/new_api_operations.tsv'".
• Dump audit_events table data into a local TSV file: sudo -u postgres psql hh -tAc "\copy (select * from audit_events) to '/tmp/new_audit_events.tsv'".
