Phase 1 - Transaction Rewrite Support: - Extended TransactionOperation enum with Rewrite variant for atomic delete + add operations - Added ManifestEntryStatus enum (Existing, Added, Deleted) - Created write_manifest_with_entries() for writing manifests with explicit status per entry - Updated commit orchestrator to handle both Append and Rewrite operations with proper summary generation Phase 2 - Compaction Module: - Created src/compact/ module with options, plan, and execute submodules - Implemented bin-pack compaction algorithm with partition scoping - Added CompactOptions for configuring target file size, max input size, min files per group - CompactionPlan creates groups using first-fit decreasing algorithm - execute_compaction reads files, concatenates batches, writes compacted files, and commits transactions per partition Phase 3 - CLI Infrastructure: - Added clap, comfy-table, bytesize, humantime dependencies - Created src/cli/ module with output formatting, catalog connection - Supports S3 Tables (--arn) and Cloudflare R2 (--r2-account/--r2-bucket) - AWS CLI style output with --output json option for scripting Phase 4 - CLI Commands: - catalog info: Show catalog connection details - namespace list/create: Manage namespaces - table list/info/files: List tables, show metadata, list data files - compact: Run bin-pack compaction with --dry-run support All tests pass and clippy is clean. --- Cargo.lock | 216 +++++++++++++++++++++++ Cargo.toml | 12 +- src/bin/icepick.rs | 92 ++++++++++ src/cli/catalog.rs | 68 +++++++ src/cli/commands/catalog.rs | 95

Expression API: Predicate types with comparison operators, AND/OR/NOT, IS NULL, IN expressions, and Datum values for all Iceberg types - ManifestReader enhancement: read_with_stats() extracts partition values, lower/upper bounds, and null counts from manifest entries - Partition evaluator: Projects predicates to partition columns with transform support (identity, year, month, day, hour, truncate) - Bounds evaluator: Evaluates predicates against column min/max stats to skip files that cannot contain matching rows -

Everything else is derived from the Iceberg REST API /v1/config endpoint. Key changes: - Add IcebergRestCatalog::from_url() constructor that fetches config and sets up vended credentials automatically - Add VendedCredentialProvider trait and support in FileIO for credential-based file access - Simplify CLI to use --catalog-url + --token (remove --arn, --r2-account, --r2-bucket options) - Add LoadTableCredentialsResponse types for /credentials endpoint - Enable reqwest default features for proper proxy support The implementation follows Iceberg REST spec: 1. Call /v1/config to get prefix and storage config 2. Use prefix for all catalog operations 3. Use /credentials endpoint for vended S3 credentials Tested against Cloudflare R2 Data Catalog successfully.

Split manifest.rs into modules (mod, extract, parse, list, file) to keep complexity under 60 per file while maintaining error handling improvements. All 85 tests pass. No breaking changes.

Field IDs must be positive per Iceberg spec, and column names must be non-empty. Note: File LOC exceeds quality threshold (501 vs 450 limit) due to added tests and documentation. The file was already at 525 lines before this PR. This is acceptable for a critical safety fix with comprehensive testing.
