Cloud Database Professional plugin for Data Loggers

Latest version: 5.0.1 build 1126. November 28, 2025.

The Cloud Database Professional export module sends parsed data from our data loggers (for example, Advanced Serial Data Logger) to SQL-compatible cloud databases: Microsoft Azure, MySQL, PostgreSQL, MariaDB, MongoDB, Amazon Aurora, and Amazon Redshift. It uses vendor drivers for direct access. That reduces system overhead and network chatter. It also lets you use database-specific features such as stored procedures.

The module writes data in real time over secure connections. If the remote database is unavailable, the plugin can keep a local backup until the connection is restored. You can queue one or more custom SQL statements. The queue can contain SELECT, INSERT, UPDATE, stored procedure calls, or database-specific commands. Returned rows can be used in subsequent statements.

Key capabilities and practical examples

• The module preserves transaction flow and offers flexible connection modes.
• Choose persistent connections for steady streams.
• Choose connect per transaction to save network resources when data is sporadic.
• Reconnection rules control how the module behaves on connection loss.
• Error handling modes let you stop on error, show a message, ignore errors but log them, or attempt reconnects.
• If desired, incoming data will be written to a temporary file when errors prevent immediate publishing. That prevents data loss.

Example: A factory sensor sends temperature readings every 10 seconds. The parser creates variables TEMP and TS. A two-statement SQL queue first runs a SELECT to compute next_id, then an INSERT uses next_id, TEMP, and TS. If the database is offline at 2025-11-28 08:00:00, the plugin writes the record to the temporary file. When the database returns, it restores and publishes queued records in order.

Integration examples with Advanced Serial Data Logger

This example shows a common workflow: the logger receives raw data, a parser extracts variables, and the Cloud Database Professional plugin publishes them.

1. Advanced Serial Data Logger - incoming serial data:

ID=17;TEMP=72.4;HUM=38;TS=2025-11-28 08:00:00

2. Parser output variables:

ID=17
TEMP=72.4
HUM=38
TS=DATE_TIME_STAMP

3. Export SQL queue (example):

SELECT (max(log_id)+1) AS next_id FROM readings

INSERT INTO readings (log_id, device_id, temp, hum, ts) VALUES (:next_id, :ID, :TEMP, :HUM, ':TS')

Brief summary

• The plugin can connect to remote databases by IP or a host name. For example: database-1.cluster-copvutiaj8an.us-east-1.rds.amazonaws.com:mydb.
• It supports several connection modes: stay connected, disconnect after each transaction, or disconnect when inactive.
• Reconnection rules: try immediately or after N seconds.
• Supports SSL-secured connections.
• It can create a temporary file backup if you need guaranteed delivery on intermittent networks.
