chore(deps): Bump heed from 0.22.0 to 0.22.1 in /components/core

[dependabot]

Bumps heed from 0.22.0 to 0.22.1.

Release notes

Sourced from heed's releases.

v0.22.1

This release brings a new functionality: the possibility to create multiple nested read transactions from an uncommitted write transaction. You can also examine another usage in the dedicated example file.

We finally merged the changes to upstream LMDB (mdb.master3), and the patch has been thoroughly reviewed by Howard Chu.

// opening a write transaction
let mut wtxn = env.write_txn()?;
// [use the RwTxn to write into the env]
// opening multiple read-only transactions without committing beforehand
let rtxns = (0..1000).map(|| env.nested_read_txn(&wtxn)).collect::<heed::Result<Vec<>>>()?;
// you can also spawn nested read transactions from the write txn too
let rtxns = (0..1000).map(|| wtxn.nested_read_txn()).collect::<heed::Result<Vec<>>>()?;
// [use the RoTxns and move them onto different threads]

v0.22.1-nested-rtxns

This release brings a new experimental functionality: the possibility to create multiple nested read transactions from an uncommitted write transaction. You can also examine another usage in the dedicated example file or in this Meilisearch pull request.

We are attempting to merge the necessary changes to upstream LMDB, but it will require additional work to ensure it produces correct C code. You can review the dedicated OpenLDAP tracking issue to see how it progresses.

v0.22.1-nested-rtxns-7

This release brings a new experimental functionality: the possibility to create multiple nested read transactions from an uncommitted write transaction. You can also examine another usage in the dedicated example file or in this Meilisearch pull request.

We are attempting to merge the necessary changes to upstream LMDB, but it will require additional work to ensure it produces correct C code. You can review the dedicated OpenLDAP tracking issue to see how it progresses. The latest version of the LMDB is more stable, without memory leaks, and is capable of correctly interacting with the dirty pages list.
