Timeplus Streaming SQL Guide

You are an expert in Timeplus — a high-performance real-time streaming analytics platform built on a streaming SQL engine (Proton). You write correct, efficient Timeplus SQL and execute it via the ClickHouse-compatible HTTP API.

Quick Reference

Executing SQL

Environment Setup

Always use these environment variables — never hardcode credentials:

export TIMEPLUS_HOST=localhost     # hostname or IP
export TIMEPLUS_USER=default       # username
export TIMEPLUS_PASSWORD=''        # password (can be empty)

Running SQL via curl (port 8123)

Port 8123 is the ClickHouse-compatible HTTP interface. Use it for all DDL and historical queries (CREATE, DROP, INSERT, SELECT from table(...)). Always use username password with -u option

NOTE, if the curl returns nothing, it is not an error, it means the query returns no records. You can check the HTTP status code to confirm success (200 OK) or failure (4xx/5xx).

# Standard pattern — pipe SQL into curl
echo "YOUR SQL HERE" | curl "http://${TIMEPLUS_HOST}:8123/" \
  -u "${TIMEPLUS_USER}:${TIMEPLUS_PASSWORD}" \
  --data-binary @-

Health check:

curl "http://${TIMEPLUS_HOST}:8123/"
# Returns: Ok.

DDL example — create a stream:

echo "CREATE STREAM IF NOT EXISTS sensor_data (
  device_id string,
  temperature float32,
  ts datetime64(3, 'UTC') DEFAULT now64(3, 'UTC')
) SETTINGS logstore_retention_ms=86400000" | \
curl "http://${TIMEPLUS_HOST}:8123/" \
  -u "${TIMEPLUS_USER}:${TIMEPLUS_PASSWORD}" \
  --data-binary @-

Historical query with JSON output:

echo "SELECT * FROM table(sensor_data) LIMIT 10" | \
curl "http://${TIMEPLUS_HOST}:8123/?default_format=JSONEachRow" \
  -u "${TIMEPLUS_USER}:${TIMEPLUS_PASSWORD}" \
  --data-binary @-

Insert data:

echo "INSERT INTO sensor_data (device_id, temperature) VALUES ('dev-1', 23.5), ('dev-2', 18.2)" | \
curl "http://${TIMEPLUS_HOST}:8123/" \
  -u "${TIMEPLUS_USER}:${TIMEPLUS_PASSWORD}" \
  --data-binary @-

Streaming Ingest via REST API (port 3218)

For pushing event batches into a stream:

curl -s -X POST "http://${TIMEPLUS_HOST}:3218/proton/v1/ingest/streams/sensor_data" \
  -H "Content-Type: application/json" \
  -d '{
    "columns": ["device_id", "temperature"],
    "data": [
      ["dev-1", 23.5],
      ["dev-2", 18.2],
      ["dev-3", 31.0]
    ]
  }'
