Nodes

Analysis

• badwords - Analyses the payload and tries to filter out any messages containing bad swear words. This only operates on payloads of type string. Everything else is blocked.

Database

• influxdb - Save and query data from an InfluxDB time series database.
• mssql-plus - Execute queries, stored procedures and bulk inserts in Microsoft SQL Server and Azure Databases SQL2000 ~ SQL2019.
• stackhero-influxdb-v2 - Save and query data from an InfluxDB v2 time series database.
• stackhero-mysql - Connect to a MySQL or a MariaDB database, using TLS (SSL) and compatible with "Caching SHA2 password" authentication method (MySQL >= 8).
• leveldb - Uses LevelDB for a simple key value pair database.
• mysql - Allows basic access to a MySQL database.
