Overview

In this tracking issue, we will be following the progress of implementing a mutable ID tracker without relying on RocksDB. This is a crucial step in enhancing the performance and scalability of our system. A mutable ID tracker is a fundamental component that enables efficient and reliable management of unique identifiers. In this article, we will delve into the details of this implementation, highlighting the key tasks, backlog items, and the expected outcomes.

Background

A mutable ID tracker is a data structure that allows for the efficient generation, storage, and retrieval of unique identifiers. In the context of our system, this component plays a vital role in ensuring data consistency and integrity. However, the current implementation relies on RocksDB, which can be a bottleneck in high-performance applications. By implementing a mutable ID tracker without RocksDB, we aim to improve the overall system performance and scalability.

Tasks

The following tasks are currently being worked on to implement a mutable ID tracker without RocksDB:

PR #6150: This pull request is the primary focus of this tracking issue. It outlines the changes required to implement a mutable ID tracker without RocksDB. The PR is still in progress, and we will be monitoring its development closely.

Backlog

In addition to the tasks mentioned above, the following backlog items need to be addressed to ensure a robust and reliable implementation:

Tests: Comprehensive testing is essential to ensure that the new implementation meets the required standards. We will be writing and running tests to validate the correctness and performance of the mutable ID tracker.
Resilience against flush failures: The new implementation should be able to handle flush failures without crashing. This requires implementing mechanisms to recover from partial flushes and ensure data consistency.
Store internal point versions as map: Currently, internal point versions are stored as an appendable list. We will be modifying the data structure to store them as a map, which will improve performance and reduce memory usage.
Integrate and use as default: Once the new implementation is complete, we will integrate it into the system and make it the default mutable ID tracker.

Expected Outcomes

The expected outcomes of this implementation are:

Improved performance: By removing the dependency on RocksDB, we expect to see significant improvements in system performance and scalability.
Enhanced reliability: The new implementation should be more resilient against flush failures and data corruption.
Simplified maintenance: With a more efficient and reliable mutable ID tracker, maintenance and troubleshooting will become easier and more efficient.
