Halaman ini menjelaskan cara mengelola file log biner sementara dan file log pengulangan InnoDB. Pemberi rekomendasi ini disebut
Mengonfigurasi ulang setelan log.
Setiap hari, sistem rekomendasi ini menganalisis hal berikut:
Penggunaan disk dalam cache pernyataan log biner dan log biner. Jika lebih dari
10% transaksi dan pernyataan non-transaksional Anda menulis ke file
sementara di disk, Mengonfigurasi ulang setelan log merekomendasikan agar Anda
meningkatkan nilai binlog_cache_size atau binlog_stmt_cache_size untuk
meningkatkan performa.
Untuk mengetahui informasi selengkapnya tentang cara meningkatkan nilai binlog_cache_size, lihat
Penggunaan memori cache. Untuk mengetahui informasi selengkapnya tentang cara meningkatkan nilai binlog_stmt_cache_size, lihat binlog_stmt_cache_size.
Rasio waktu tunggu versus waktu penulisan untuk log redo InnoDB. Pemberi rekomendasi ini menyarankan untuk menaikkan nilai innodb_log_buffer_size jika transaksi menunggu buffer log untuk dibersihkan.
Untuk mengetahui informasi selengkapnya tentang cara meningkatkan nilai innodb_log_buffer_size, lihat

Menerapkan rekomendasi
Untuk menerapkan rekomendasi ini, lakukan salah satu hal berikut:
Tingkatkan nilai binlog_stmt_cache_size atau binlog_cache_size.
Untuk mengetahui informasi selengkapnya tentang cara meningkatkan nilai binlog_stmt_cache_size, lihat
binlog_stmt_cache_size. Untuk mengetahui informasi selengkapnya tentang cara meningkatkan nilai binlog_cache_size, lihat Penggunaan memori cache.
Rancang transaksi Anda agar berukuran kecil dan menggunakan lebih sedikit cache pernyataan log biner dan log biner.
Tingkatkan nilai innodb_log_buffer_size. Untuk mengetahui informasi selengkapnya tentang
cara meningkatkan nilai innodb_log_buffer_size, lihat
Penggunaan memori buffer.
Tingkatkan ukuran persistent disk sehingga Anda memiliki permintaan I/O paralel yang cukup untuk meningkatkan rasio operasi baca terhadap operasi tulis untuk file log.
