-- Primeiro criar o LOGFILE GROUP

-- 5. ALTERNATIVAS PARA InnoDB
-- ============================================================================

/*
Como InnoDB não suporta múltiplos datafiles por tablespace,
as alternativas são:

1. USAR AUTO-EXTEND (recomendado)
   - O arquivo cresce automaticamente conforme necessário
   - Mais simples de gerenciar

2. MÚLTIPLOS TABLESPACES
   - Criar vários tablespaces com 1 datafile cada
   - Distribuir tabelas entre eles

3. PARTICIONAMENTO
   - Particionar tabelas grandes
   - Cada partição pode estar em tablespace diferente
*/

-- Exemplo: Múltiplos tablespaces InnoDB
CREATE TABLESPACE ts_innodb_part1
ADD DATAFILE '/disk1/mysql/ts_part1.ibd'
AUTOEXTEND_SIZE = 64M
ENGINE = InnoDB;

CREATE TABLESPACE ts_innodb_part2
ADD DATAFILE '/disk2/mysql/ts_part2.ibd'
AUTOEXTEND_SIZE = 64M
ENGINE = InnoDB;

CREATE TABLESPACE ts_innodb_part3
ADD DATAFILE '/disk3/mysql/ts_part3.ibd'
AUTOEXTEND_SIZE = 64M
ENGINE = InnoDB;

-- Tabela particionada usando múltiplos tablespaces
CREATE TABLE vendas_particionada (
    id INT AUTO_INCREMENT,
    data_venda DATE,
    valor DECIMAL(10,2),
    PRIMARY KEY (id, data_venda)
)
PARTITION BY RANGE (YEAR(data_venda)) (
    PARTITION p2023 VALUES LESS THAN (2024) TABLESPACE ts_innodb_part1,
    PARTITION p2024 VALUES LESS THAN (2025) TABLESPACE ts_innodb_part2,
    PARTITION p2025 VALUES LESS THAN (2026) TABLESPACE ts_innodb_part3
);

-- RESUMO FINAL
-- ============================================================================

/*
CAPACIDADES POR ENGINE:

InnoDB:
✗ Não suporta múltiplos datafiles no CREATE TABLESPACE
✗ Não suporta ALTER TABLESPACE ADD DATAFILE
✓ Suporta auto-extend (recomendado)
✓ Alternativa: múltiplos tablespaces + particionamento

NDB:
✓ Suporta múltiplos datafiles via ALTER TABLESPACE
✓ Ideal para distribuição de carga em cluster
✓ Permite adicionar datafiles dinamicamente
✓ Melhor controle sobre localização dos arquivos

RECOMENDAÇÃO:
- InnoDB: Use auto-extend ou particionamento
- NDB: Use múltiplos datafiles conforme necessário

# Introducing InnoDB Cluster
#
# This Python script is designed to set up an InnoDB Cluster in a sandbox.
#
# Note: Change the sandbox directory to match your preferred directory setup.
#
# The steps include:
# 1) Create the sandbox directory
# 2) Deploy instances
# 3) Create the cluster
# 4) Add instances to the cluster
# 5) Show the cluster status
