| <div class="block"><p>An implementation of an application timeline store backed by leveldb.</p> |
| |
| <p>There are three sections of the db, the start time section, |
| the entity section, and the indexed entity section.</p> |
| |
| <p>The start time section is used to retrieve the unique start time for |
| a given entity. Its values each contain a start time while its keys are of |
| the form:</p> |
| <pre> |
| START_TIME_LOOKUP_PREFIX + entity type + entity id</pre> |
| |
| <p>The entity section is ordered by entity type, then entity start time |
| descending, then entity ID. There are four sub-sections of the entity |
| section: events, primary filters, related entities, |
| and other info. The event entries have event info serialized into their |
| values. The other info entries have values corresponding to the values of |
| the other info name/value map for the entry (note the names are contained |
| in the key). All other entries have empty values. The key structure is as |
| follows:</p> |
| <pre> |
| ENTITY_ENTRY_PREFIX + entity type + revstarttime + entity id |
| |
| ENTITY_ENTRY_PREFIX + entity type + revstarttime + entity id + |
| EVENTS_COLUMN + reveventtimestamp + eventtype |
| |
| ENTITY_ENTRY_PREFIX + entity type + revstarttime + entity id + |
| PRIMARY_FILTERS_COLUMN + name + value |
| |
| ENTITY_ENTRY_PREFIX + entity type + revstarttime + entity id + |
| OTHER_INFO_COLUMN + name |
| |
| ENTITY_ENTRY_PREFIX + entity type + revstarttime + entity id + |
| RELATED_ENTITIES_COLUMN + relatedentity type + relatedentity id |
| |
| ENTITY_ENTRY_PREFIX + entity type + revstarttime + entity id + |
| DOMAIN_ID_COLUMN |
| |
| ENTITY_ENTRY_PREFIX + entity type + revstarttime + entity id + |
| INVISIBLE_REVERSE_RELATED_ENTITIES_COLUMN + relatedentity type + |
| relatedentity id</pre> |
| |
| <p>The indexed entity section contains a primary filter name and primary |
| filter value as the prefix. Within a given name/value, entire entity |
| entries are stored in the same format as described in the entity section |
| above (below, "key" represents any one of the possible entity entry keys |
| described above).</p> |
| <pre> |
| INDEXED_ENTRY_PREFIX + primaryfilter name + primaryfilter value + |
