Class CompatibilityTableRecord

java.lang.Object

org.gridgain.internal.orthus.compatibility.table.CompatibilityTableRecord

public class CompatibilityTableRecord
extends Object

A single row from the pushdown compatibility table.

The table is published by GridGain as a system view (SYSTEM.COMPATIBILITY_CONFIGURATION) and consumed by the MariaDB storage-engine client to decide whether an expression subgraph can be safely pushed down to GridGain for evaluation. Each record binds an AST node identity (type + name) to a checker configuration (rules) that the client instantiates and runs against resolved nodes at query-planning time.

CompatibilityTableRecord

public CompatibilityTableRecord(int id,

Creates a compatibility table record.

Parameters:

id - Surrogate key; used to address this row when mutating the live model via the system view.

type - Node category the entry applies to (e.g. "ITEM", "DATA_TYPES", "FALLBACK").

name - AST node identity within the category: a function name, an operator token ("+", "-", …), or "*" as a catch-all wildcard.

rules - JSON-encoded checker descriptor — a checker_id plus its construction_args. Parsed by the client's checker registry at initialisation time.

comment - Free-form human-readable note; not used at runtime. May be null or empty.
