| 7 Common - Database index | |
| 8 ----------------------- | |
| 9 | |
| 258 | 10 * Performance of joins in LookupResources: Create cached statement for |
| 11 LookupResources, that are grouped to search up to, say, 10 tags, | |
| 12 instead of recompiling for each request | |
| 371 | 13 * Do not log "DatabaseCannotSerialize" errors in the plugin but only |
| 14 in Orthanc after all retries have been made. | |

| 502 | 19 * Implement "large queries" for: |
| 20 - updating all metadata of a resource at once | |
| 21 - update all maindicomtags of 4 resource levels at once | |
| 22 | |
| 23 | |

| 25 Common - Storage area | |
| 26 --------------------- | |
| 27 | |
| 28 * Implement the "StoreDicom" option from the default filesystem | |

| 196 | 31 |
| 259 | 32 * Performance: Add a pool of connections to PostgreSQL/MySQL, as |
| 33 already done in the database index plugins | |
| 34 | |
| 360 | 35 ---------- |
| 36 PostgreSQL | |
| 37 ---------- | |
| 38 | |
| 477 | 39 * Check if we can force the schema that is used. By default, Orthanc |
| 40 is using the 'public' schema but, after a wrong command, we have seen | |
| 41 a DB where there was a 'AttachedFiles' table in the public schema and another one in a | |
| 42 'MyPacs' schema and Orthanc was actually using the 'MyPacs.AttachedFiles' table !!! | |
| 43 Orthanc was then seeing only the most recent attached files !!! | |
