Looked a bit at flux GitOps - this will be hard to deploy to existing cluster. Maybe not an I&P thing.

Got filter-engine working for dates with cast to VARCHAR then cast to TIMESTAMP. Raised issue about searching on keys where type is mixed (https://github.com/rucio/rucio/issues/3750)

08/12/2021

IRIS meeting. Notes on DIRAC/STFC cloud:

• https://github.com/DIRACGrid/VMDIRAC (allows dirac to spawn VMs to run jobs on cloud).
• Sirius ceph cluster (768Tb of NVMe - 220Tb usable), allocated to VMs depending on flavour.
• Arided (SSD ceph, 400Tb usable). High performance, users expected to move data off it when not using.
• Castor is tape service used by LHC (150Pb) -> replaced by ANtares Q1 2022, accessed through Xrootd though plans for more.

Continued Rucio development (requests history comments + metadata)

Useful commands for testing requests in local env:

curl -i https://rucio/auth/userpass -H "X-Rucio-Account: root" -H "X-Rucio-Username: ddmlab" -H "X-Rucio-Password: secret" --insecure
curl -i https://localhost/requests/history/list?request_states=S\&src_rse=MOCK\&dst_rse=MOCK3\&offset=2\&limit=1 -H "X-Rucio-Auth-Token: <token>" --insecure

Metadata status: mostly done for postgres, but:

• how to get it to work for dates?
• searching on keys where the type is mixed? casting will fail for string -> ints, raises DataError.
• guid, name indexes: https://github.com/rucio/rucio/blob/release-1.26-LTS/lib/rucio/core/did.py ?
• always cast ints to floats, otherwise with a key with value e.g. 1.1 and searching key>1, 1.1. would be cast to int.
