接口interface io.agentscope.extensions.jdbc.dialect.table 2.x

SnapshotDialect

public interface SnapshotDialect

源码Source io/agentscope/extensions/jdbc/dialect/table/SnapshotDialect.java:32–72

定义快照 Dialect契约的接口。位于 io.agentscope.extensions.jdbc.dialect.table 包。核心成员包括 snapshotTableName、snapshotCreateTableDdls、snapshotUpsert、snapshotSelect、snapshotExists。

Table-domain dialect interface for the snapshots table.

Stores binary workspace tar archives keyed by snapshot_id.

Method names are prefixed with snapshot to avoid collision when the aggregate class implements multiple table-domain interfaces.
