+# Introspection tables in the internal schema
+
+## Overview
+The internal schema contains the following introspection tables
+
+- `steampipe_connection`
+Lists all connections as defined in the connection config. 
+- ``
+Lists all plugin instances as defined in the connection config.
+- `steampipe_plugin_limiter`
+Lists all plugin Limiters as defined either in the plugin binary or the plugin conneciton block
+
+
+## Lifecycle
+
+### Startup
+#### steampipe_connection
+- Every time the server is started, the connections are loaded from the table into ConnectionState structs. 
+- The table is then deleted and recreated - this is to handle any updates to the table structure
+- The connection states are set to either `pending` (if currently `ready`) or `incomplete` (if not).
+  (These states will be updated by RefreshConnections.)
+- The connections are written back to the table
+- RefreshConnections is triggered - this will apply any necessary conneciton updates and set the states of the connections 
+to either `ready` or `error`
+
+#### steampipe_plugin
+- Every time the server is started, table is then deleted and recreated - this is to handle any updates to the table structure
+- The configured plugin instances are written back to the table
+
+
+(See `postServiceStart` in pkg/db/db_local/internal.go)
+
+### Connection config file changed
+
+The when a connection file is changed the ConnectionWatcher calls `pluginManager.OnConnectionConfigChanged`, and then calls 
+`RefreshConnections` asyncronously
+
+`OnConnectionConfigChanged`calls:
+- `handleConnectionConfigChanges`
+- `handlePluginInstanceChanges`
+- `handleUserLimiterChanges`
+
+
+`handleConnectionConfigChanges` determines which connections have been added, removed and deleted. It then builds a set of SetConnectionConfigRequest, one for each plugin instance with changed connections
+
+`handlePluginInstanceChanges` determines which plugins have been added, removed and deleted. 
+It updates the `steampipe_plugin` table.
+###TODO if the plugin for an instance changes, all connections must be dropped and re-added  
+
+
+
+`handleUserLimiterChanges` determines which plugin instances have changed limiter definitions. 
+It updates the `steampipe_rate_limiter` table and makes a `SetRateLimiters` call to all plugin instances 
+with updated rate limiters.  
+
+
+### TODO: if a plugin instance has no more connections, we should stop it
+
+`RefreshConnections` updates the plugin schemas to correspond with the updated connection config
+

+## steampipe_connection
+
+### Usage
+
+`steampipe_connection` table is used to determine whether a connection has been loaded yet.
+This is used to allow us to execute queries without wasiting for all connecitons to load. Instead, we execute the query,
+and if it fails with a relation not found error, we poll the coneciton state table until the conneciton is ready.
+Then we retry the query.
