QuestDB

The robomotion questdb CLI connects to QuestDB for time-series database operations. It executes SQL queries optimized for time-series data, inserts records with timestamps, and manages connections to QuestDB instances.

When to use

Execute time-series SQL queries with time-based aggregations
Insert time-series data points into QuestDB tables
Query sensor, metrics, or event data with time filters

Prerequisites

robomotion CLI installed
Package installed: robomotion install questdb
QuestDB connection credentials configured via Robomotion vault

IMPORTANT: Session Mode Required for Multi-Step Operations

Each CLI command runs as a separate process — connection IDs from connect do NOT persist across calls. You MUST use --session on connect and pass --session-id to all subsequent commands.

Workflow

Install (once): robomotion install questdb

Connect with session:

robomotion questdb questdb_connect --session --output json
# → {"outConnectionId":"<conn-id>","session_id":"<session-id>"}

Use the returned conn-id and session-id in all subsequent commands:

robomotion questdb questdb_execute_query --conn-id "<conn-id>" --session-id "<session-id>" --output json

Disconnect when done:

robomotion questdb questdb_disconnect --conn-id "<conn-id>" --session-id "<session-id>" --output json

Always append --output json to get structured JSON results.

Commands Reference

robomotion questdb questdb_connect --session --output json Connects to QuestDB database and returns a client ID for subsequent operations
robomotion questdb questdb_disconnect --client-id --session-id "<session-id>" --output json Closes the QuestDB connection and releases resources
robomotion questdb questdb_execute_query --client-id --query --parameters [--60] --session-id "<session-id>" --output json Executes a custom SQL query on QuestDB
robomotion questdb questdb_select --client-id --table --columns --where-clause --order-by --limit [--60] --session-id "<session-id>" --output json Selects rows from a QuestDB table with optional filtering
robomotion questdb questdb_insert --client-id --table --columns --values [--60] --session-id "<session-id>" --output json Inserts rows into a QuestDB table
