🧩 wbjdbc v2.0 — JDBC para Python (com suporte a Informix, Pooling, Async e Cache)

wbjdbc é uma biblioteca JDBC moderna e otimizada para Python, agora com recursos de pool de conexões, execução assíncrona, operações em lote, cache de metadados e mapeamento de tipos.
Totalmente compatível com versões anteriores (v1.x) e pronta para produção.


🚀 Principais Recursos

  • 🔄 Pool de Conexões — Gerencia múltiplas conexões com reaproveitamento automático.
  • Execução em Lote — Até 10x mais rápido em inserções/atualizações massivas.
  • 🧵 Execução Assíncrona — Suporte a dezenas de queries simultâneas.
  • 🧠 Cache de Metadados — Reduz 95–99% das consultas de schema repetidas.
  • 🧩 Mapeamento Automático de Tipos — Conversão bidirecional entre JDBC e Python.
  • 🧮 Métricas e Logging Estruturado — Estatísticas detalhadas de desempenho.
  • ⚙️ Configuração via .env ou Variáveis de Ambiente
  • Compatível 100% com versões anteriores

🧰 Instalação

pip install wbjdbc

💡 Uso Básico

from wbjdbc import connect_optimized

conn = connect_optimized(
    db_type="informix-sqli",
    host="server",
    database="db",
    user="user",
    password="pass",
    server="informix"
)

df = conn.query("SELECT * FROM clientes LIMIT 10")
print(df)

⚙️ Execução em Lote

data = [(1, "Alice"), (2, "Bob")]
conn.execute_batch("INSERT INTO clientes VALUES (?, ?)", data)

🧵 Execução Assíncrona

future = conn.execute_async("SELECT COUNT(*) FROM clientes")
print(future.result())

📈 Métricas e Logging

  • Tempo médio, p50, p95 e p99 de queries
  • Estatísticas de pool, cache e conexões
  • Exportação JSON para Prometheus ou Grafana

🔧 Configuração (.env)

DB_TYPE=informix-sqli
DB_HOST=server
DB_DATABASE=db
DB_USER=user
DB_PASSWORD=pass
POOL_MIN=10
POOL_MAX=20
CACHE_TTL=600

🧾 Changelog

v2.0.0

  • Novo pool de conexões (thread-safe)
  • Execução assíncrona e em lote
  • Cache de metadados com invalidação
  • Métricas detalhadas e logs estruturados
  • Total compatibilidade com v1.x

  • 100% Backward Compatible

🧰 Installation

pip install wbjdbc

💡 Basic Usage

from wbjdbc import connect_optimized

conn = connect_optimized(
    db_type="informix-sqli",
    host="server",
    database="db",
    user="user",
    password="pass",
    server="informix"
)

df = conn.query("SELECT * FROM customers LIMIT 10")
print(df)

⚙️ Batch Execution

data = [(1, "Alice"), (2, "Bob")]
conn.execute_batch("INSERT INTO customers VALUES (?, ?)", data)
