集約の状態を保存するためのテーブルであり、集約のリプレイを高速化するためのテーブルです。スナップショット保存後にもイベントは保存されるため、最新の集約状態を表さない場合あります。 26 | 27 | | キー名 | 説明 | 具体的な値 | 備考 | 28 | |:--------|:-----------------------------------------------------------------|:-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|:---|

スナップショット冗長化機能が無効な場合はskey=0にスナップショットが保存されるだけですが、有効にした場合はスナップショットはskey=0以外にskey=aggregate.seq_nr()の2件保存されます。スナップショットを保存するたびにskey=aggregate.seq_nr()のスナップショットが増えますが、あなたはスナップショットは上限を指定できます(デフォルトは1)。上限を超えた場合は古いスナップショットから削除されます。デフォルトでは、クライアント主導で削除されます。TTLを使ってDynamoDB自身に削除させることもできます。 38 | - aidとseq_nrはGSIが適用されており、リプレイ時はこのインデックスを利用されます。 39 | 40 | ### イベント及びスナップショットの書き込み 41 | 42 | 1. 集約にてコマンドが受理されると、最新のseq_nrが付与されたイベントが生成されます。 43 | 2. 生成されたイベントはjournalテーブルに書き込まれます。ただし、この書き込みは必ずsnapshotテーブルと同じトランザクションで行われ、versionが一致する条件下で実施されます。初回のイベント以外は、snapshotのpayloadを更新することはオプションです。 44 | 45 | ### イベント及びスナップショットを使って集約をリプレイする 46 | 47 | 1. 集約のIDを指定して、スナップショットを取得します。 48 | 2. 取得した集約のIDとスナップショットのシーケンス番号以降のイベントをjournalテーブルから読み込みます。 49 | 3. 読み込んだイベントをスナップショットに適用することで、最新の集約状態を取得します。 50 |

Some of those programs are provided under licenses deemed 10 | incompatible with the GPLv2 by the Free Software Foundation and others. 11 | For example, the package includes programs licensed under the Apache 12 | License, Version 2.0 and may include FreeType. Such programs are licensed 13 | to you under their original licenses. 14 | 15 | Oracle facilitates your further distribution of this package by adding the 16 | Classpath Exception to the necessary parts of its GPLv2 code, which permits 17 | you to use that code in combination with other independent modules not 18 | licensed under the GPLv2. However, note that this would not permit you to 19 | commingle code under an incompatible license with Oracle's GPLv2 licensed 20 | code by, for example, cutting and pasting such code into a file also 21 | containing Oracle's GPLv2 licensed code and then distributing the result. 22 | 23 | Additionally, if you were to remove the Classpath Exception from any of the 24 | files to which it applies and distribute the result, you would likely be 25 | required to license some or all of the other code in that distribution under 26 | the GPLv2 as well, and since the GPLv2 is incompatible with the license terms 27 | of some items included in the distribution by Oracle, removing the Classpath 28 | Exception could therefore effectively compromise your ability to further 29 | distribute the package. 30 | 31 | Failing to distribute notices associated with some files may also create 32 | unexpected legal consequences. 33 | 34 | Proceed with caution and we recommend that you obtain the advice of a lawyer 35 | skilled in open source matters before removing the Classpath Exception or 36 | making modifications to this package which may subsequently be redistributed 37 | and/or involve the use of third party software. 38 | -------------------------------------------------------------------------------- /docs/javadoc/legal/ASSEMBLY_EXCEPTION: -------------------------------------------------------------------------------- 1 | 2 | OPENJDK ASSEMBLY EXCEPTION 3 | 4 | The OpenJDK source code made available by Oracle America, Inc. (Oracle) at 5 | openjdk.org ("OpenJDK Code") is distributed under the terms of the GNU 6 | General Public License version 2 7 | only ("GPL2"), with the following clarification and special exception. 8 | 9 | Linking this OpenJDK Code statically or dynamically with other code 10 | is making a combined work based on this library. Thus, the terms 11 | and conditions of GPL2 cover the whole combination. 12 | 13 | As a special exception, Oracle gives you permission to link this 14 | OpenJDK Code with certain code licensed by Oracle as indicated at 15 | https://openjdk.org/legal/exception-modules-2007-05-08.html 16 | ("Designated Exception Modules") to produce an executable, 17 | regardless of the license terms of the Designated Exception Modules, 18 | and to copy and distribute the resulting executable under GPL2, 19 | provided that the Designated Exception Modules continue to be 20 | governed by the licenses under which they were offered by Oracle. 21 | 22 | As such, it allows licensees and sublicensees of Oracle's GPL2 OpenJDK Code 23 | to build an executable that includes those portions of necessary code that 24 | Oracle could not provide under GPL2 (or that Oracle has provided under GPL2 25 | with the Classpath exception). If you modify or add to the OpenJDK code, 26 | that new GPL2 code may still be combined with Designated Exception Modules 27 | if the new code is made subject to this exception by its copyright holder. 28 | -------------------------------------------------------------------------------- /docs/javadoc/legal/jquery.md: -------------------------------------------------------------------------------- 1 | ## jQuery v3.7.1 2 | 3 | ### jQuery License 4 | ``` 5 | jQuery v 3.7.1 6 | Copyright OpenJS Foundation and other contributors, https://openjsf.org/ 7 | 8 | Permission is hereby granted, free of charge, to any person obtaining 9 | a copy of this software and associated documentation files (the 10 | "Software"), to deal in the Software without restriction, including 11 | without limitation the rights to use, copy, modify, merge, publish, 12 | distribute, sublicense, and/or sell copies of the Software, and to 13 | permit persons to whom the Software is furnished to do so, subject to 14 | the following conditions: 15 | 16 | The above copyright notice and this permission notice shall be 17 | included in all copies or substantial portions of the Software. 18 | 19 | THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, 20 | EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF 21 | MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND 22 | NONINFRINGEMENT.
