<span class="diff-added" style="background-color: #eaffea; color: #000000; display: block; white-space: pre">+ * インデックスの差分更新について</span>
<span class="diff-added" style="background-color: #eaffea; color: #000000; display: block; white-space: pre">+ * MariaDBの欠点について、他のデータベースとの比較を交えて伺いたいと思います。</span>
<span class="diff-added" style="background-color: #eaffea; color: #000000; display: block; white-space: pre">+ * 運用上考慮する必要がある点があれば。</span>
<span class="diff-added" style="background-color: #eaffea; color: #000000; display: block; white-space: pre">+ * 全文検索が得意なこと、苦手なこと。</span>
<span class="diff-added" style="background-color: #eaffea; color: #000000; display: block; white-space: pre">+ * MariaDB10系以降でMroonga storage modeの使い方を知りたいです</span>
<span class="diff-added" style="background-color: #eaffea; color: #000000; display: block; white-space: pre">+ * インデックス生成のコストについて</span>
<span class="diff-added" style="background-color: #eaffea; color: #000000; display: block; white-space: pre">+ * MySQLやPostgreSQLなどとLuceneなどを使った全文検索エンジンをどのように使い分けているか。どのようなことを考慮して使い分けているのか</span>
<span class="diff-added" style="background-color: #eaffea; color: #000000; display: block; white-space: pre">+ * SolrやElasticsearchのようなガチの環境ではなくRDBでカバーしているもので大規模なものだとどの程度のデータ規模まで実用に耐えるものなのでしょうか。チューニングやスキーマ、中に入っているデータのパターンにもよるかとは思いますが、どのくらいの目処で専用エンジンに載せ替えていくのがいいのかという判断材料があると助かります。</span>
<span class="diff-added" style="background-color: #eaffea; color: #000000; display: block; white-space: pre">+ * MySQL/PostgrerSQLとも、形態素解析エンジンとして、Mecabを使っているが、Mecabの開発が終わっていそうなのが気になる。他の日本語形態素解析エンジンに切り替える予定等あるのか。</span>
