C_TRANGER¶

Time-range database manager — wraps timeranger2 for CRUD operations on time-series topics.

Property	Value
States	`ST_STOPPED`, `ST_IDLE`

Command	Description
`topics`	List all topics.
`create-topic`	Create a new topic.
`open-topic`	Open an existing topic.
`delete-topic`	Delete a topic.
`open-list` / `close-list`	Open or close a record list (one-shot snapshot with `return_data=1`, else a live list collecting realtime appends).
`get-list-data`	Retrieve an open list’s data.
`list-keys`	List a topic’s keys with their record counts (`[{key, records}]`).
`open-iterator` / `close-iterator`	Open/close a stateful per-key iterator (row index only, no upfront load) for cursor pagination.
`get-page`	Get a page `{total_rows, pages, data}` from an open iterator (`from_rowid` 1-based, `limit`, optional `backward`).
`open-rt` / `close-rt`	Open/close a realtime feed on a topic key (no history load); new appends are published as `EV_TRANGER_RECORD_ADDED` to subscribers.
`add-record`	Append a record.
`print-tranger`	Dump tranger state.
`desc`	Describe topic schema.

Hierarchical tree database manager — manages TreeDB instances on top of timeranger with JSON schema support.

Property	Value
States	`ST_STOPPED`, `ST_IDLE`

Attribute	Type	Description
`path`	`string`	Storage path.
`filename_mask`	`string`	Filename pattern.
`master`	`bool`	`TRUE` for master, `FALSE` for read-only replica.
`exit_on_error`	`bool`	Exit on schema errors.

Command	Description
`open-treedb` / `close-treedb`	Open or close a treedb instance.
`delete-treedb`	Delete a treedb and its data.
`create-topic` / `delete-topic`	Manage topics within a treedb.

Node resource interface for TreeDB — full CRUD and graph operations on tree nodes with linking, snapshots, and import/export.

Property	Value
States	`ST_STOPPED`, `ST_IDLE`

Command	Description
`create-node` / `update-node` / `delete-node`	CRUD operations on nodes.
`get-node` / `list-nodes`	Retrieve nodes.
`link-nodes` / `unlink-nodes`	Manage parent-child relationships.
`parents` / `children`	Navigate the graph.
`hooks` / `links`	Inspect hook and fkey relationships.
`jtree`	Get a node’s full subtree as JSON.
`shoot-snap` / `activate-snap` / `deactivate-snap`	Snapshot management.
`list-snaps` / `snap-content`	Inspect snapshots.
`import-db` / `export-db`	Bulk import/export.
`desc`	Describe topic schema.

Simple resource persistence — stores each resource as a flat JSON file.

Property	Value
States	`ST_STOPPED`, `ST_IDLE`
