Imeji Performance eSciDoc

This is a protected page.
This page contains information about different technology possibilities to implement Faces 4.0. To achieve the requirements the performance of the different technologies is of most interest.

Open Questions | Status |
|---|---|---|---|---|---|---|
| eSciDoc Item Retrieval (SOAP) | 0,6 sec | 2,65 sec | Fast development, as already implemented in other solutions All eSciDoc services can be used (versioning, statistics, aa etc.) |
Very slow Extra release, pid assignment etc. is necessary |
-- | Tested |
| eSciDoc Item Retrieval (REST) | 0,5 sec | 2,2 sec | All eSciDoc services can be used (versioning, statistics, aa etc.) retrieve Operation is faster (approx. half a second per item) |
Slow Extra release, pid assignment etc. is necessary |
-- | Tested |
| eSciDoc IngestHandler | -- | 0,4 sec | -- | No PID assigned User needs special role: ingester Items seems not to be indexed: blocker! |
-- | Tested |
| eSciDoc ContentRelation | -- | -- | -- | CR is not under version control | Cannot be updated any more when released once (The documentation says public-status of an CR must not be "released"). Thus, CRs are not feasible for this purpose | Tested |
| eSciDoc as archive, MD in Triple Store | -- | -- | Very fast | synchronization issues Evtl. redundant data aa has to be implemented |
How do we perform status updates? (escidoc has to know the status, not only the triple store) maybe this alternative can be acceptable in decoupled scenario e.g. ingest/updates are done directly on the triple store, they are stored with delay in eSciDoc core - in this case, AA must be taken seriously as well see also File:Batch metadata update.pptx |

| eSciDoc Core Performance Tuning | -- | -- | All solutions could profit from this | Development has to be together with FIZ, so that we do not develop our own eSciDoc which we have to adopt with every FW release Development process can be very long Code seems to be complex to understand |
Would FIZ be willing to provide development resources to perform this task? | |
| No eSciDoc | -- | -- | Can be much faster | Services can not be reused High development effort |
What to use as storage? Fedora, DB? |
(*) Only update operation
(**) Whole process form create to release, with eventually necessary retrieves, pid assignment, submit etc...
