We can disable saving of the history either via command-line parameter --disable-history, or by setting disabled = True in the history section of the cqlshrc. Both options will read existing history, and just won't save new commands.
Update help and docs for cqlsh history.
Add startup info logline whenr history logging is enabled.
Add a fix for cqlshrc file path not correctly expanding.
Includes the Backport of
Allows users to change cqlsh history location using env variable

Rewrites ANN search query execution logic to more efficiently merge graph search results using
similarity score-ordered (descending) iterators to merge segments efficiently. Allows for reduced memory
consumption during queries, reduced impact of overwrites and tombstones, selective re-querying of
minimally necessary graphs, and reduced shuffling of PrimaryKey objects.

This is a partial solution to IllegalStateException thrown by VectorPostings. It works by using a single shard at L0 when a vector index is present. As noted in the jira ticket, there are edge cases that may still produce errors, notably the case where there are multiple data directories.
The key trade offs here are related to the time complexity for search. Since graph search is log(n), and searching m graphs is m * log(n), we see better search performance by building bigger graphs which is essentially log(m * n). We could pre-shard, which comes at a cost of increased search time complexity.
