As discussed in RFC-14, this change implements the first phase of JDBC incremental puller.
It consists following changes:
- JdbcSource: This class extends RowSource and implements
fetchNextBatch(Option<String> lastCkptStr, long sourceLimit)
- SqlQueryBuilder: A simple utility class to build sql queries fluently.
- Implements two modes of fetching: full and incremental.
Full is a complete scan of RDBMS table.
Incremental is delta since last checkpoint.
Incremental mode falls back to full fetch in case of any exception.
Main functions:
Support create table for hoodie.
Support CTAS.
Support Insert for hoodie. Including dynamic partition and static partition insert.
Support MergeInto for hoodie.
Support DELETE
Support UPDATE
Both support spark2 & spark3 based on DataSourceV1.
Main changes:
Add sql parser for spark2.
Add HoodieAnalysis for sql resolve and logical plan rewrite.
Add commands implementation for CREATE TABLE、INSERT、MERGE INTO & CTAS.
In order to push down the update&insert logical to the HoodieRecordPayload for MergeInto, I make same change to the
HoodieWriteHandler and other related classes.
1、Add the inputSchema for parser the incoming record. This is because the inputSchema for MergeInto is different from writeSchema as there are some transforms in the update& insert expression.
2、Add WRITE_SCHEMA to HoodieWriteConfig to pass the write schema for merge into.
3、Pass properties to HoodieRecordPayload#getInsertValue to pass the insert expression and table schema.
Verify this pull request
Add TestCreateTable for test create hoodie tables and CTAS.
Add TestInsertTable for test insert hoodie tables.
Add TestMergeIntoTable for test merge hoodie tables.
Add TestUpdateTable for test update hoodie tables.
Add TestDeleteTable for test delete hoodie tables.
Add TestSqlStatement for test supported ddl/dml currently.
* Reduces log level for too verbose messages from info to debug level.
* Sort config output.
* Code Review : Small restructuring + rebasing to master
- Fixing flaky multi delta streamer test
- Using isDebugEnabled() checks
- Some changes to shorten log message without moving to DEBUG

* [HUDI-845] Added locking capability to allow multiple writers
1. Added LockProvider API for pluggable lock methodologies
2. Added Resolution Strategy API to allow for pluggable conflict resolution
3. Added TableService client API to schedule table services
4. Added Transaction Manager for wrapping actions within transactions
- Add a config to allow parsing custom date format in `DatePartitionPathSelector`. Currently it assumes date partition string in the format of `yyyy-MM-dd`.
- Fix a bug where `UnsupportedOperationException` was thrown when sort `eligibleFiles` in-place. Changed to sort it and store in a new list.
* [HUDI-1538] Try to init class trying different signatures instead of checking its name.
* Removed unused imports

Addresses leaks, perf degradation observed during testing. These were regressions from the original rfc-15 PoC implementation.
* Pass a single instance of HoodieTableMetadata everywhere
* Fix tests and add config for enabling metrics
- Removed special casing of assumeDatePartitioning inside FSUtils#getAllPartitionPaths()
- Consequently, IOException is never thrown and many files had to be adjusted
- More diligent handling of open file handles in metadata table
- Added config for controlling reuse of connections
- Added config for turning off fallback to listing, so we can see tests fail
- Changed all ipf listing code to cache/amortize the open/close for better performance
- Timelineserver also reuses connections, for better performance
- Without timelineserver, when metadata table is opened from executors, reuse is not allowed
- HoodieMetadataConfig passed into HoodieTableMetadata#create as argument.
- Fix TestHoodieBackedTableMetadata#testSync
* [HUDI-1479] Use HoodieEngineContext to parallelize fetching of partition paths
* Adding testClass for FileSystemBackedTableMetadata
