| ClassSqliteSaverA checkpoint saver that stores checkpoints in a SQLite database. | https://reference.langchain.com/python/langgraph.checkpoint.sqlite/SqliteSaver |
| ClassAsyncSqliteSaverAn asynchronous checkpoint saver that stores checkpoints in a SQLite database.
This class provides an asynchronous interface for saving and retrieving checkpoints
using a SQLite database. It's design | https://reference.langchain.com/python/langgraph.checkpoint.sqlite/aio/AsyncSqliteSaver |
| Functionbuild_delta_stage2_sqlStage-2 per-channel UNION ALL fetching writes from writes.
One branch per channel with a non-empty chain. Each branch inlines its
own IN (?, ?, ...) placeholder list because sqlite has no array-b | https://reference.langchain.com/python/langgraph.checkpoint.sqlite/_delta/build_delta_stage2_sql |
| Functionstep_walk_with_rowProcess one streamed stage-1 row in the merged ancestor walk.
The cursor returns (cid, type, blob) rows in walk order starting at
target. The first row is target itself and is skipped (target's own

| Functionbuild_delta_channels_writes_historyDemux stage-2 rows per channel; produce per-channel histories.
Stage-2 rows are
(checkpoint_id, channel, task_id, idx, type, value, task_path).
Final write order is oldest→newest globally and `writ | https://reference.langchain.com/python/langgraph.checkpoint.sqlite/_delta/build_delta_channels_writes_history |
| Functionsearch_whereReturn WHERE clause predicates for (a)search() given metadata filter
