gatewayd-plugin-cache

gatewayd-plugin-cache

GatewayD plugin for caching query results.

Features

• Basic caching of database responses to client queries
• Invalidate cached responses on upsert and delete (table-based)
• Periodic cache invalidation
• Support for setting expiry time on cached data
• Support for caching responses from multiple databases on multiple servers
• Support nested queries: joins, unions, multi-table selects, and the like
• Detect client's chosen database from the client's startup message
• Metrics for quantifying cache hits, misses, gets, sets and deletes
• Logging at various levels
• Configurable via environment variables

Build

To build the plugin, run the following command:

make && make checksum

Running the above command causes these command to run:

1. go mod tidy && go build -ldflags "-s -w" ⇒ compiles and generates gatewayd-plugin-cache.
2. sha256sum -b gatewayd-plugin-cache ⇒ generates SHA256 hash.

For now, the generated hash should be manually replaced with the old one in gatewayd_plugins.yaml.
