+**Status**
+APPROVED
+
+**Date**
+January 5, 2024
+
+**Problem**
+
+For some of Memgraph workloads, text search is a required feature. We don't
+want to build a new text search engine because that's not Memgraph's core
+value.
+
+**Criteria**
+
+- easy integration with our C++ codebase
+- ability to operate in-memory and on-disk
+- sufficient features (regex, full-text search, fuzzy search, aggregations over
+  text data)
+- production-ready
+
+**Decision**
+
+All known C++ libraries are not production-ready. Recent Rust libraries, in
+particular [Tantivy](https://github.com/quickwit-oss/tantivy), seem to provide
+much more features, it is production ready. The way how we'll integrate Tantivy
+into the current Memgraph codebase is via
+[cxx](https://github.com/dtolnay/cxx). **We select Tantivy.**

+**Status**
+PROPOSED
+
+**Date**
+January 10, 2024
+
+**Problem**
+
+In order to enhance Memgraph to have High Availability features as requested by
+customers, we want to have reliable coordinators backed by RAFT consensus algorithm. Implementing
+RAFT to be correct and performant is a very challenging task. Skillful Memgraph
+engineers already tried 3 times and failed to deliver in a reasonable timeframe
+all three times (approximately 4 person-weeks of engineering work each time).
+
+**Criteria**
+
+- easy integration with our C++ codebase
+- heavily tested in production environments
+- implementation of performance optimizations on top of the canonical Raft
+  implementation
+
+**Decision**
+
+There are a few, robust C++ implementations of Raft but as a part of other
+projects or bigger libraries. **We select
+[NuRaft](https://github.com/eBay/NuRaft)** because it focuses on delivering
+Raft without bloatware, and it's used by
+[Clickhouse](https://github.com/ClickHouse/ClickHouse) (an comparable peer to
+Memgraph, a very well-established product).

+
+**Author**
+Marko Budiselic (github.com/gitbuda)
+
+**Status**
+ACCEPTED
+
+**Date**
+January 23, 2024
+
+**Problem**
+
+Interacting with data (reads and writes) on disk in a concurrent, safe, and
+fast way is a challenging task. Implementing all low-level primitives to
+interact with various disk hardware efficiently consumes significant
+engineering people. Whenever Memgraph has to store data on disk (or any
+other colder than RAM storage system), the problem is how to do that in the
+least amount of development time while satisfying all functional requirements
+(often performance).
+
+**Criteria**
+
+- working efficiently in a highly concurrent environment
+- easy integration with Memgraph's C++ codebase
+- providing low-level key-value API
+- heavily tested in production environments
+- providing abstractions for the storage hardware (even for cloud-based
+  storages like S3)
+
+**Decision**
+
+There are a few robust key-value stores, but finding one that is
+production-ready and compatible with Memgraph's C++ codebase is challenging.
+**We select [RocksDB](https://github.com/facebook/rocksdb)** because it
+delivers robust API to manage data on disk; it's battle-tested in many
+production environments (many databases systems are embedding RocksDB), and
+it's the most compatible one.

+# Architecture Decision Records
+
+Also known as ADRs. This practice has become widespread in many
+high performing engineering teams. It is a technique for communicating
+between software engineers. ADRs provide a clear and documented
+history of architectural choices, ensuring that everyone on the
+team is on the same page. This improves communication and reduces
+misunderstandings. The act of recording decisions encourages
+thoughtful consideration before making choices. This can lead to
+more robust and better-informed architectural decisions.
+
+Links must be created, pointing both to and from the Github Issues
+and/or the Notion Program Management "Initiative" database.
+
+ADRs are complimentary to any tech specs that get written while
+designing a solution. ADRs are very short and to the point, while
+tech specs will include diagrams and can be quite verbose.
+
+## HOWTO
+
+Each ADR will be assigned a monotonically increasing unique numeric
+identifier, which will be zero-padded to 3 digits. Each ADR will
+be in a single markdown file containing no more than one page of
+text, and the filename will start with that unique identifier,
+followed by a camel case phrase summarizing the problem.  For
+example: `001_architecture_decision_records.md` or
+`002_big_integration_cap_theorem.md`.
+
+We want to use an ADR when:
+1. Significant Impact: This includes choices that affect scalability, performance, or fundamental design principles.
+1. Long-Term Ramifications: When a decision is expected to have long-term ramifications or is difficult to reverse.
+1. Architectural Principles: ADRs are suitable for documenting decisions related to architectural principles, frameworks, or patterns that shape the system's structure.
+1. Controversial Choices: When a decision is likely to be controversial or may require justification in the future.
+
+The most senior engineer on a project will evaluate and decide
+whether or not an ADR is needed.
+
+## Do
+
+1. Keep them brief and concise.
+1. Explain the trade-offs.
+1. Each ADR should be about one AD, not multiple ADs
+1. Don't alter existing information in an ADR. Instead, amend the ADR by adding new information, or supersede the ADR by creating a new ADR.
+1. Explain your organization's situation and business priorities.
+1. Include rationale and considerations based on social and skills makeups of your teams.
+1. Include pros and cons that are relevant, and describe them in terms that align with your needs and goals.
+1. Explain what follows from making the decision. This can include the effects, outcomes, outputs, follow ups, and more.
+
+## Don't
+
+1. Try to guess what the executive leader wants, and then attempt to please them. Be objective.
+1. Try to solve everything all at once. A pretty good solution now is MUCH BETTER than a perfect solution later. Carpe diem!
+1. Hide any doubts or unanswered questions.
+1. Make it a sales pitch. Everything has upsides and downsides - be authentic and honest about them.
+1. Perform merely a superficial investigation. If an ADR doesn't call for some deep thinking, then it probably shouldn't exist.
+1. Ignore the long-term costs such as performance, tech debt or hardware and maintenance.
+1. Get tunnel vision where creative or surprising approaches are not explored.
+
+# Template - use the format below for each new ADR
+
+1. **Author** - who has written the ADR
+1. **Status** - one of: PROPOSED, ACCEPTED, REJECTED, SUPERSEDED-BY or DEPRECATED
+1. **Date** - when the status was most recently updated
+1. **Problem** - a concise paragraph explaining the context
+1. **Criteria** - a list of the two or three metrics by which the solution was evaluated, and their relative weights (importance)
+1. **Decision** - what was chosen as the way forward, and what the consequences are of the decision
+
