# sql-batcher
A Clojure library designed to run large sql updates/deletes in batches
[](https://circleci.com/gh/punit-naik/sql-batcher/tree/master)
[](https://clojars.org/org.clojars.punit-naik/sql-batcher)
## Rationale
If an update/delete query is doing a large table scan and spanning a large number of rows, that table could be blocked for a potentially very long time. To avoid this, we run our update/delete queries in batches of relatively small sizes, based on the primary key(s) of the table to on which the updates/deletes are supposed to run.
