CrateDB PDO Driver
Frequently asked questions about Crate Pdo
- What is crate/crate-pdo?
- crate/crate-pdo is the CrateDB PDO driver for PHP and provides a PDO transport to CrateDB. It lets PHP applications issue SQL against CrateDB through PDO. It is not a Laravel-specific database driver and does not by itself add Laravel query builder or Eloquent support.
- Is crate/crate-pdo a Laravel database driver?
- No. PDO is Laravel's database foundation, but Laravel also needs a connector, query grammar, schema grammar, and post-processor. crate-pdo supplies only the PDO transport, so it is not a drop-in Laravel database integration. Treat it as a low-level transport and build or document any Laravel layer yourself.
- Can I use CrateDB as my Laravel application's primary database with crate-pdo?
- That is not recommended. CrateDB lacks the transactional, constraint, and relational semantics Laravel assumes for primary OLTP workloads. Use it as a secondary store for analytics, reporting, metrics, logs, or append-heavy data while keeping core business logic in MySQL or PostgreSQL.
- How do I install crate/crate-pdo?
- Add the package through Composer using its crate/crate-pdo name. Before adopting it, confirm the required PHP extensions, PDO configuration, and supported CrateDB versions in the package documentation. Run a small connection test against a real CrateDB instance rather than assuming it works with your stack.
- Does crate/crate-pdo support Laravel 10, Laravel 11, PHP 8.2, and PHP 8.3?
- The assessment does not confirm specific version support, and the package has low visible adoption. Run a technical spike against your exact Laravel and PHP versions, including Laravel 10/11 and PHP 8.2/8.3 if those are your targets. Verify connectivity, prepared statements, parameter binding, error codes, and schema operations before committing.
- Can I use Laravel's pgsql connector with CrateDB instead of crate-pdo?
- CrateDB offers PostgreSQL wire-protocol compatibility, so Laravel's existing pgsql PDO path may work for some queries. Evaluate crate-pdo against that baseline instead of assuming it is the default choice. Test the specific SQL, parameter binding, error handling, and schema operations your application needs.
- Does crate-pdo support prepared statements, bound parameters, and transactions?
- Test prepared statements and bound parameters as part of any proof of concept because full PDO behavior is a key risk. Do not assume transaction support matches PostgreSQL or MySQL semantics. CrateDB's transaction, consistency, and failure behavior differs, so validate writes, idempotency, and retries explicitly.
- What Laravel features break when using CrateDB?
- Expect friction with migrations, schema builder, auto-increment assumptions, foreign keys, transactions, upserts, and Eloquent's timestamp and primary-key conventions. Prefer raw SQL or a dedicated query service for CrateDB. Validate every query-builder method used in production and keep CrateDB access behind repository interfaces.
- Is crate/crate-pdo production-ready and actively maintained?
- The package shows low visible adoption at around 35 GitHub stars and an unknown maintenance posture. The main risks are driver abandonment, incomplete PDO behavior, weak version compatibility, and missing test coverage. Apache-2.0 licensing reduces fork risk but does not guarantee ongoing support or security updates, so assign ownership internally.
- What are good use cases for CrateDB in a Laravel application?
- Best-fit workloads are analytics dashboards, time-series and event data, audit or search views, and read-heavy reporting. Use CrateDB as a secondary connection behind repository interfaces or dedicated query services. Keep transactional business logic in your primary OLTP database and roll out CrateDB behind feature flags with fallback.
