NAME ^

OpenResty::Limits - Various contraints used in the OpenResty server

SYNOPSIS ^

    use OpenResty::Limits;

    print join("\n",
        $MODEL_LIMIT,
        $VIEW_LIMIT,
        $FEED_LIMIT,
        $ROLE_LIMIT,
        $COLUMN_LIMIT,
        $RECORD_LIMIT,
        $INSERT_LIMIT,
        $POST_LEN_LIMIT,
        $MAX_SELECT_LIMIT,
        $PASSWORD_MIN_LEN,
        $VIEW_MAX_LEN,
        $ACTION_MAX_LEN,
        $ACTION_CMD_COUNT_LIMIT,
        $ACTION_REC_DEPTH_LIMIT,
    );

DESCRIPTION ^

This module defines various constants which limits the resources each OpenResty account could use, like the number of different objects (models, rows, views, and etc.).

These constants are not truly constants. Some of them could be overridden by some config options specified in etc/site_openresty.conf. So different servers may have (very) different limitations.
