Operational Notes

A current dump of the Conseil database in pg_dump tar format can be found at https://conseil-snapshots.s3.amazonaws.com/conseil_20200324.tar.gz.

Due to an oversight, the release is missing two neccessary database indexes which causes sluggish Lorre sunc times. They can be manually added using the following SQL:

CREATE INDEX ix_operations_cycle ON tezos.operations USING btree("cycle");

CREATE INDEX ix_operations_kind ON tezos.operations USING btree("kind");
